“side” of which you upgrade while the other side continues to run your applications without interruption. See the Stratus ftServer: Active Upgrade User’s Guide (R017W) or the Active Upgrade online help for more information.
ftSys Management Console
The ftSys Management Console (ftSMC) is a graphical user interface that enables you to monitor and manage your system’s fault-tolerant software and hardware. See
ActiveService Network
Your ftServer system offers an optional, secure network, the ActiveService Network
(ASN). ASN enables the CAC or your authorized Stratus service representative to provide remote monitoring, diagnosis, troubleshooting, and problem-resolution services to your systems 24 hours a day, 7 days a week. Access to the ASN requires a service contract with Stratus or an authorized Stratus service representative and is implemented across a modem or over the Internet.
Having ASN connectivity enables:
Your system to send alerts (call-home alarm messages) to the CAC or your authorized Stratus service representative when unusual events occur on the system
The CAC or your authorized Stratus service representative to access the system through a connection to the ASN
Your system can connect to the ASN through:
A modem connected to the system
The Internet
The VTM console or an ftGateway system
N O T E
An ftServer 2600, 4500, or 6300 system running ftSSS for the Windows Operating System, Release 6.0.0, provides only ftGateway slave support and cannot serve as an ftGateway master. For ftGateway master support, use an ftServer system that runs a version of ftSSS for the
Windows Operating System, Release 5.3.
Internet-based ASN connects over a secure path to your authorized Stratus service representative.

After verifying a hardware problem, your authorized Stratus service representative can send out a replacement CRU.
See the Stratus ActiveService Network Configuration Guide (R072) for more information, and online help for ftSys Management Console (ftSMC) for instructions in how to configure ASN alarm notification by email.
Virtual Technician Module Console
The Virtual Technician Module (VTM) console is a Web-based console that enables you, the CAC, or your authorized Stratus service representative to control, monitor, and diagnose the system. You can access the VTM console over a LAN, or the Internet, if
Internet connectivity is available. You can use the VTM console even if the host system’s operating system is unresponsive and its network connections are lost. VTM console functionality also includes:
Remote Keyboard, Video, Mouse (KVM) support
Access to attached storage
Diagnosis of a system that is powered off (however, standby power must be available)
Power-cycling of a system
Remote KVM Console enables you to manage the host computer remotely over the
Web-based console. Using Remote KVM Console, you can view the remote system desktop and redirect its local keyboard and mouse.
A VTM requires assignment of two IP addresses, either static or from a Dynamic Host
Configuration Protocol (DHCP) server. See
“Configuring Static IP Addresses for the
VTM Network Ports” on page 2-7
.
Disk-Management Tools
Disk-management tools enable you to monitor disk status, mirror entire physical disks, create logical volumes, mirror volumes across multiple disks, and perform other data-storage operations.

System Software Features
System Software Features
ftServer System Software has features designed to support fault-tolerant operation and
high availability. These features include fault-tolerant, fail-safe software , Stratus services
,
open architecture drivers , and
Rapid Disk Resync disk mirroring
.
N O T E ftServer 2600, 4500, and 6300 systems do not support the
Windows Server 2008 BitLocker Drive Encryption feature.
Fail-Safe Software
ftServer System Software works in conjunction with lockstep technology to increase system reliability. Fail-safe software features capture issues and report them to the
CAC or your authorized Stratus service representative. Even data in memory can be constantly protected and maintained.
Stratus's hardened device drivers prevent software failures, and Stratus provides an embedded open-driver technology that enables third-party device drivers to access hardening capabilities.
Stratus Services
Stratus provides software fault-tolerant services that run on your system as
Windows-based services. These services constantly monitor for, and respond to, hardware problems. Applications do not need customization to support the services.
These services start automatically when the system boots and remain running during normal operation. If a situation requires system administrator intervention, you can use
for details.
See the Stratus ftServer Systems: Technical Reference Guide (R550) for descriptions of the Stratus services.
Open Driver Architecture
Your ftServer system supports both vendor-supplied drivers and Stratus-supplied drivers for PCI adapters. ftServer systems support vendor-supplied drivers for the PCI adapters that you supply. For PCI adapters that Stratus provides, Stratus supplies drivers that it has enhanced with support for surprise removal.
In addition, your ftServer system uses other drivers developed by Stratus. These drivers allow the system and all PCI devices to integrate with the ASN, and provide management of all system devices and device fault-tolerance.
1-4 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
System Software Features
ASN integration provides:
Automatic reporting of device failures to the CAC or your authorized Stratus service representative
Notification to you by the CAC or your authorized Stratus service representative when a device fails
Inventory reporting to the CAC or your authorized Stratus service representative that lists all PCI devices in the system
Comprehensive debug information about all devices in the system for use by the
CAC or your authorized Stratus service representative in troubleshooting your system
Management of PCI devices includes:
On your ftServer system, hot-plug support alerts the plug-and-play manager to bring a device into service or take it out of service. You can initiate bring-up or bring-down from ftSMC. Hot-plug support also initiates discovery of newly attached or removed devices.
N O T E
You must remove the CPU- I
O enclosure from the system in order to remove a PCI adapter.
Display of information so that you know whether removing a device will compromise the system. The drivers can set LEDs and values in ftSMC that let you know whether you can safely remove a component.
Display of information in ftSMC about a device’s fault-tolerance, including:
Automatic restart of failed devices. The device will be restarted after transient faults, until it falls below its mean-time-between faults (MTBF) threshold.
Tracking the MTBF of a device and management of the device when it experiences faults. You can set parameters to take the device out of service when the device experiences an unacceptable MTBF. You can configure the rules for MTBF management.
Rapid Disk Resync Disk Mirroring
Rapid Disk Resync (RDR) disk-mirroring technology provides faster resynchronization of mirrored disks than other mirroring methods after transient failures or when a single disk is briefly removed from service. For optimal performance, use RDR to mirror disks in internal storage.

Starting Up and Shutting Down A System
Starting Up and Shutting Down A System
For normal system startup and shutdown, and to completely remove power from the system, see the operation and maintenance guide for your system.
!
C A U T I O N
Always shut down the operating system before turning the system power off.
N O T E S
1. Give the system time to recover automatically
from problems. If the system hangs for any reason
while it is booting, wait at least ten minutes before intervening manually.
2. If a system contains failed components, it may attempt to boot for an extended period of time. This is because the system makes up to six attempts to boot, each time trying with a different combination of components. You can monitor the boot process on the screen or in a VTM console session.
You can accomplish an orderly shutdown of the system from a remote computer by accessing the Windows desktop and executing a Shut Down command.
You must physically be at the system to see the message indicating that it is safe to power off the system. To turn off power, use the power button on the machine, the standby circuit-breaker switches, or the VTM console. Note, however, that the
Windows Shut Down command automatically powers down the system.
Enabling the Power Button on the Machine
The power button on the machine performs an orderly shutdown when pressed once.
However, if no one is currently logged on to the system, the power button may not work properly on all versions of the Windows operating system. You may have to enable the power button on the machine to operate correctly in the event that no one is logged onto a system.
To enable the power button on the machine to shut down a system onto which no one has yet logged, enable the following Windows Security option:
Shutdown: Allow system to be shutdown without having to log on
2-2 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Starting Up and Shutting Down A System
To set the shutdown option on a Windows Server 2003 system
1. Refer to the Windows Help topic Opening the Local Group Policy Editor
2. Follow the instructions for a Local Computer or a Group Policy object.
To set the shutdown option on a Windows Server 2008 system
1. Click Start, Administrative Tools, and Local Security Policies.
2. Under Security Settings, expand Local Policies, and double-click Security
Options.
3. In the Policy pane on the right-hand side, scroll down to and right-click Shutdown:
Allow system to be shutdown without having to log on.
4. Select Properties.
5. Click Enabled on the Local Security Setting tab, and then click OK.
CPU Element Resynchronization
Each system houses two CPU-I/O enclosures. Each CPU-I/O enclosure includes a
CPU element and an I/O element. ftSMC represents these elements in the following
nodes:
CPU Enclosure - 0 and CPU Enclosure - 1
I/O Enclosure - 10 and I/O Enclosure - 11
Discussions of CPU enclosures and I/O enclosures apply equally to the corresponding elements of CPU-I/O enclosures, unless otherwise specified.
A CPU element returning to service must resynchronize with the functioning CPU element. A CPU element requires resynchronization:
After you bring down and then bring up a CPU element
After a transient CPU element error
After you power down a system and then power it up
During online BIOS upgrade
During part of the resynchronization period, the system does not respond to network connections. Therefore, it is important to set the timeout period and/or number of retries for network applications to be large enough to prevent timeouts during resynchronization. The length of the resynchronization period is proportional to the amount of system memory configured.
By default, resynchronization occurs as soon as the CPU element that was taken out of service is determined to be operational or the failed enclosure is replaced. However, you can defer resynchronization to a more convenient time, such as an off-peak period.

See
“Managing CPU Element Bringup” on page 2-4 for information about scheduling
CPU bringup.
Managing CPU Element Bringup
You can specify two times of day at which to enable, or to which to defer, the return to service of CPU elements that have been removed from service (shot). You use two commands—Enable CpuBoard Bringup and Defer CpuBoard Bringup—which the
Windows Scheduler executes. You also specify two times of day: one time when an offline CPU element can be brought up, and another time to which CPU Bringup is deferred. See ftSMC Help for instructions in setting these commands.
When Scheduler executes the commands, Enable CpuBoard Bringup changes the
CpuBringUpPolicy property under the Srabid driver to Enable Bringup. This setting enables CPU elements that were removed from service to come back into service. It also brings up any CPUs that are in the Removed from Service state for a reason of
Deferred BringUp, as long as they don't exceed the MTBF threshold.
When Scheduler executes the Defer CpuBoard Bringup command, it changes the
CpuBringUpPolicy property under the Srabid driver to Defer Bringup. With this setting, if a CPU element is removed from service, the CPU elements come back into service at different times.
For example, consider the situation in which Defer CpuBoard Bringup is scheduled for every day at 8:00 a.m., and Enable CpuBoard Bringup is scheduled for every day at
9:00 p.m. In this case, if any CPU element gets removed from service after 8:00 a.m., it will not be allowed to come back into service until after 9:00 p.m., when Scheduler executes Enable CpuBoard Bringup. At that time, Enable CpuBoard Bringup will automatically bring up any CPU element that has been deferred between 8:00 a.m. and
9:00 p.m.

Understanding Floppy Disk Drive Volume Letters
The operating system generally assigns the drive letter A to the optional floppy disk drive when the drive is first connected to a USB port. If you subsequently connect the drive to a different USB port or if the I/O element or element fails over, the operating system may assign the drive letter B to the floppy disk drive.
2-12 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Using Serial Ports
Using Serial Ports
Your system has two serial ports. Serial port 2 (Windows COM2) is always available for use by the operating system and is accessible to devices connected to its serial connector at the rear of the ftServer system. However, the availability of Serial port 1
(Windows COM1) is dependent on the presence or absence of an ASN modem in the ftServer system:
If no ASN modem is installed in the ftServer system, Serial port 1 is also always available for use by the operating system and accessible to devices connected to
its serial connector at the rear of the ftServer system.
If the ASN modem is installed, Serial port 1 is normally dedicated to the ASN modem, is not available for general use by the operating system, and is not accessible to devices connected to its serial connector at the rear of the ftServer system.
You can determine the presence or absence of the ASN modem by examining the
ftServer Call Home Modem - 0 node in ftSMC, which will be shown as offline if no
modem is present.
!
C A U T I O N
Although the serial ports have a nominal maximum speed of 115,200 bps, they do not operate reliably at speeds higher than 57,600 bps; so you should not attempt to run them at higher speeds.
Understanding Uninterruptible Power Supplies
Your ftServer system supports the use of an uninterruptible power supply (UPS) to power the system without interruption during short outages, and to gracefully shut the system down during longer power outages. As part of your fault-tolerant strategy, use a UPS qualified by Stratus.
For information about qualified UPS models, see the site planning guide for your system.
For UPS installation details, see the Stratus ftServer System Software: Installation
and Configuration for Windows Systems (R002W).
If your ftServer system is not connected to a qualified UPS, the system may not have time to shut down gracefully in the event of a power failure, thus limiting your recovery procedure options. In that case, you have to reboot the system and verify that your file systems were not corrupted. Contact the Stratus CAC or your authorized Stratus service representative for further assistance.
Operating and Monitoring Your System
2-13
Understanding SNMP Traps
Maintaining System Power During a UPS Failure
When you use a UPS qualified by Stratus, you connect that UPS to one half of the system. If a failure occurs in the UPS or in the UPS power source (for example, if the
UPS is unplugged) and the backup battery runs low, the system continues to operate if the power to the non-UPS half of the system is unaffected by the failure.
Changing the IP Address of Systems with a UPS
If you change the IP address on the system, update the configuration on the UPS with the new IP address. If you do not update the UPS, and power to the system is automatically removed after a power failure, the system does not restart when power is restored.
N O T E
Assign a static IP address to the network interface that provides the connection to the UPS.
To change the IP address of systems with a UPS
1. In a Web browser, enter http:// and the IP address of the UPS; for example,
http://
xxx.xxx.xxx
.
2. Log into the APC Web site using the user name and password.
The IP address home page appears.
3. Click the UPS tab on the home page.
4. Click clients in the left-hand column beneath Power Chute®.
5. Click the IP address that you want to change.
6. In the Client IP address box, overwrite the existing IP address with the new IP address.
7. Click Apply.
Understanding SNMP Traps
Your ftServer system supports the Microsoft SNMP Agent, which enables third-party
Enterprise Management consoles to remotely monitor the systems. The ftServer
SNMP Agent provides a standard mechanism for monitoring the status of systems and for receiving alarms from the systems.
During instances of system malfunction or in response to a system event, such as a firmware update, you may see multiple traps in third-party management consoles for various devices. For instance, if a PCI adapter fails, the SNMP agent may send traps not only for the adapter but also for its slot. You may safely disregard these traps.
2-14 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Understanding Updates and Hotfixes
See the Stratus ftServer System Software: Installation and Configuration for Windows
Systems (R002W) for SNMP configuration information.
Understanding Updates and Hotfixes
See the following Web page for an up-to-date statement of Stratus’ policy on installing upgrades and hotfixes to the operating system: http://www.stratus.com/support/releasepolicy
You can greatly reduce application downtime when you upgrade software by installing and using the optional Stratus ftServer Active Upgrade software. If you do plan to install and use Active Upgrade software, be sure to keep system files on a separate disk from data files. See the Stratus ftServer: Active Upgrade User’s Guide (R017W) for more information.
Avoiding Problems
To take full advantage of your system’s fault-tolerant features and to avoid problems, observe the following when setting up and operating your system:
Do not attempt to boot the system from a network drive. Booting the system
from a network drive is not supported.
Do not use Windows Device Manager to disable devices except in
documented special situations. Using Windows Device Manager to disable
devices can interfere with the proper operation of your system. The correct way to take devices out of service and return them to service is through the ftSMC snap-in.
However, to handle special situations, the system documentation may instruct you to use Windows Device Manager.
Do not turn on the Emulex elxstor.sys LightPulse Storport Miniport driver
services; they will interfere with the fault-tolerant operation of your system.
Upon installation, these services are set to manual.
Do not install devices unless they have been tested and certified as
compatible with ftServer systems. Installing devices that have not been tested
and certified to be compatible with your ftServer system can reduce the fault tolerance of your system. If you want to install a device that has not been certified, contact your account team.

CPU and I/O Enclosures and Elements
Each system houses two CPU- I
O enclosures. Each CPU- I O enclosure contains a
CPU element and an I/O element joined to the same board. You can monitor each CPU element and I/O element separately. ftSMC represents these elements in the following nodes:
CPU Enclosure - 0 and CPU Enclosure - 1
I/O Enclosure - 10 and I/O Enclosure - 11
Descriptions of CPU elements and I/O elements apply to the elements of both
CPU- I
O enclosures, unless otherwise specified.
Primary and Secondary CPU-I/O Enclosures
Both CPU-I/O enclosures in an ftServer system process every instruction in lockstep, but only one CPU-I/O enclosure is the primary, or active, enclosure at a time. The other
CPU-I/O enclosure is the secondary enclosure; it assumes the role of primary enclosure only if the previously primary enclosure fails or is taken out of service. But,
3-12 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
CPU and I/O Enclosures and Elements
under certain circumstances, you can force the secondary enclosure to become the primary enclosure.
For example, your authorized Stratus service provider might ask you to switch the primary enclosure for troubleshooting purposes. Or, if you are about to run the Active
Upgrade process, you might want the enclosure that is connected to UPS-protected power (CPU enclosure 0, I/O enclosure 10) to be the primary enclosure, because this provides better protection for your system if power fails during the upgrade (especially while your system is in split mode).
Switching the Primary CPU-I/O Enclosure
If you need a particular CPU-I/O enclosure to be primary, first check the operational state of that enclosure. If it is currently the secondary enclosure, you can manually set that enclosure to become the primary enclosure.
To check the operational state of an I/O enclosure
1. Open ftSMC.
2. Expand ftServer (Local).
3. Expand ftServer I/O Enclosures.
4. Click I/O Enclosure - n. (To prepare for the Active Upgrade process, check the state of I/O Enclosure - 10.)
5. Verify that the value for Op State: Reason is Primary and the value for
ActiveCompatibilityFlag is True.
If the value for Op State: Reason is Secondary and the value for
ActiveCompatibilityFlag is False, you can manually set the enclosure to be the
primary enclosure.
To make an I/O enclosure the primary I/O enclosure
1. Open ftSMC.
2. Expand ftServer (Local).
3. Expand ftServer I/O Enclosures.
4. Expand I/O Enclosure - n. (To prepare for the Active Upgrade process, expand I/O
Enclosure - 10)
5. Right-click on the I/O enclosure.
6. Click Make Active Compatible.
If you are preparing for the Active Upgrade process, you might need to wait 5-10 minutes for the system components to stabilize and return to full duplex mode before running a readiness check.

Data Fault Tolerance
Your ftServer system offers these methods of ensuring data fault tolerance and continuous availability of its disk media:
Rapid Disk Resync (RDR), a disk-replicating technology, is supported on the internal disk drives.
On optional ftScalable Storage systems, you use the RAIDar graphical user interface to create virtual disks in the external storage. See the ftScalable Storage:
Getting Started Guide (R601) for details.
After creating the virtual disks using RAIDar, you must use Windows Disk
Management or another disk-management tool to initialize the virtual disks and format the volumes on them.
If you are not using RDR or RAIDar, see your disk-management tool documentation for information on how to create striped volumes across the mirrored internal disks.

Guidelines for System Disks
N O T E
Create a backup of the system disk with which to restart the system in the unlikely event of a system failure. See the Stratus ftServer System Software: Installation and
Configuration for Windows Systems (R002W).
Guidelines for System Disks
On the system disk, the IPL procedure creates a boot partition, which contains the operating system and all of its components.
Because the system disk and boot partition hold system-critical files, such as the paging file and system event files, limit the traffic to this disk to system traffic only.
The internal storage of your ftServer system supports Serial Attached SCSI (SAS). The system’s disks are located in a disk tray that connects to the system backplane.
N O T E
You may use any slots for any disks, with the following two exceptions. First, pair disks in partner I/O elements, not within the same element, to promote fault-tolerance.
Second, use a SAS disk for the system boot disk and locate it in the bottom-most slot (Slot-1).
You can greatly reduce application downtime when you upgrade software by installing and using the optional Stratus ftServer Active Upgrade software. If you plan to install and use Active Upgrade software, be sure to keep system files on a separate disk from data files. See the Stratus ftServer: Active Upgrade User’s Guide (R017W) for more information.
Using RDR for Mirroring and Fault Tolerance
Use RDR disk mirroring to configure and create managed disks in internal storage.
With RDR disk mirroring, you mirror pairs of physical disks to create RDR virtual disks.
Each pair of mirrored disks constitutes one RDR virtual disk. RDR offers faster resynchronization of mirrored disks than other mirroring methods after transient failures or when a single disk is briefly removed from service.
4-2 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Using RDR for Mirroring and Fault Tolerance
N O T E
In RDR terminology, an individual physical disk is also called a plex, and an RDR virtual disk is also called a
LUN, for logical unit.
The data on one disk of the RDR virtual disk pair is replicated in full—that is, mirrored or duplex—on its corresponding partner disk, irrespective of volume or partition layout.
However, an RDR virtual disk may also be simplex (consisting of only one physical disk). A simplex RDR virtual disk may contain mirrored volumes created using third-party disk management facilities. If all volumes on a simplex RDR disk are mirrored with other disks in the system, then the simplex RDR disk is effectively duplex
(mirrored).
If you are upgrading a system’s disks from a non-RDR to an RDR configuration, the existing disks must provide adequate space for metadata. Metadata is “data about data” that the RDR software stores on disks to implement disk management. When you configure a disk for RDR, the system displays an error message if the disk does not have adequate space. The disk being upgraded should be a basic disk. A basic disk is one that is divided into partitions.
RDR virtual disks appear in ftSMC under the Logical Disk Information node. In this location, the details pane presents the location of the physical disks in the RDR virtual disk in these properties:
Disk Enclosure Slot: DevicePath[2]
Disk Enclosure Slot: DevicePath[1]
However, the DevicePathID property that appears at the top of the details pane, and which has a number like 39/7, does not indicate a hardware component and does not signify the physical disks’s location in the system; it merely identifies the virtual disk to system-management software.
See
for the RDR disk numbering scheme.
Automatic Virtual Disk Expansion
An RDR virtual disk includes an automatic disk-capacity expansion feature. If you replace the physical disks (plexes) of an RDR virtual disk with larger physical disks,
RDR automatically recognizes the resulting larger virtual disk, which enables the system to use the added disk capacity.
Note, however, that a virtual disk cannot be larger than the smaller of its two physical disks. For example, if each physical disk of an RDR virtual disk is 80 gigabytes (GB), the virtual disk is an 80-GB virtual disk. If you replace one 80-GB physical disk with a
Disk Storage Management
4-3
Managing RDR Disks
160-GB physical disk, the virtual disk remains an 80-GB disk, the smaller of the two physical disks. But if you replace the other 80-GB physical disk with another 160-GB physical disk, the RDR virtual disk automatically updates to 160 GB. ftSMC reports the capacity of physical disks and virtual disks in the Capacity property in two different locations:
The physical disk Capacity property appears in the ftSMC details pane under
ftServer I/O Enclosure - 10, Storage Enclosure - 40, Slot - n, Disk - n.
The virtual disk Capacity property appears in the ftSMC details pane under
Logical Disk Information, RDR Virtual Disk - n.
Automatic virtual disk expansion does not work on dynamic virtual disks—that is, RDR virtual disks that have been converted to dynamic disks by Windows Disk
Management. (A dynamic disk consists of a single partition that is divided into volumes.
Dynamic disks can be combined with other disks to form volumes that expand beyond a single disk.)

Prioritizing resynchronization
To use RDR to mirror dynamic disks, see the Stratus ftServer System Software:
Installation and Configuration for Windows Systems (R002W).
You can also set disk parameters from the SCSI Port Duplex Driver - Sradisk_Driver node shortcut menu in the ftSMC.
Creating a First RDR Virtual Disk
To create an RDR virtual disk, you use the Create RDR Virtual Disk action from the context menu of a disk. Then you add a physical disk to the RDR virtual disk on another physical disk to make the two physical disks into a single RDR virtual disk.
If you create the first RDR disk (plex) on a disk that already has data on it (for instance, a system disk), make sure that both disks have
the same capacity , that the disks are
basic disks (not dynamic), and that the second disk (the one to be the mirror) has no partitions.
To configure the first plex of an RDR virtual disk
1. In ftSMC, expand ftServer (Local), ftServer I/O Enclosures, I/O Enclosure - 10
(or 11), Storage Enclosure - 40, Slot - n, and then right-click Disk - n.

If necessary, follow the prompts to reboot the system.
Mirroring Disks Using RDR
The procedure used to mirror disks with RDR is the same used to upgrade a disk to
RDR. To mirror an RDR disk, you give the Add Physical Disk To RDR Virtual Disk command on an unconfigured disk (the target) and overwrite it with an existing
RDR-configured disk (the source).
If you are upgrading disks to use RDR, be sure that the disks are basic disks. (Basic
disks are divided into partitions. Dynamic disks consist of a single partition that is divided into volumes. Dynamic disks can be combined with other disks to form volumes that expand beyond a single disk.) If the disks have been configured as dynamic disks,
convert the disks to basic disks before upgrading them to RDR (refer to Windows online
help).
Although you can only create RDR disks from basic disks, you can make RDR disks dynamic if your policies require it.
If you insert a blank (having no disk signature or volume ID), non-RDR-configured disk into a slot previously occupied by an RDR disk whose partner slot is currently occupied by an RDR disk, the system automatically adds the inserted disk to the RDR virtual disk.
Not all RDR commands and procedures are valid on all physical disks. Error messages appear if you attempt an invalid RDR command. Error messages also suggest possible corrective actions, where applicable.
Some RDR configuration changes, especially those made on simplex RDR virtual disks, may require the operating system to restart in order to complete. When the
Windows restart warning appears, you can restart the system immediately or defer restarting until a more convenient time.
RDR Disk Numbering
Internal storage disks and RDR virtual disks are labeled with numerical IDs that
appear in ftSMC. See Table 4-1
for the locations of the Disk and RDR Virtual Disk nodes.

Adding a Physical Disk to an RDR Virtual Disk
To add a physical disk to an RDR virtual disk, perform these steps.
1. In ftSMC, expand I/O Enclosure, Storage Enclosure - 40 and Slot - n, and then select the disk (the target disk) that you want to add to the RDR virtual disk.
The target disk must be an unconfigured (nonRDR-configured) disk.
2. Right-click the target disk and select Add Physical Disk to RDR Virtual Disk.
The following disk wizard appears.
Disk Storage Management

Managing RDR Disks
3. Click Next.
The Select a source disk dialog box appears, identifying the target disk and the disk or disks available for being chosen as sources.
A source disk will already be selected by default in the Select a source disk dialog box, if storage-enclosure rules allow.
4. If a source disk is not already selected in the dialog box, choose a source from the available disks listed in the right-hand box within the dialog box, and c lick
Next.
The RDR virtual source disk will overwrite the unconfigured target disk, making it a mirror of the RDR virtual source disk.
In this example, only one source disk, the disk in 10/40/2/2, is available.
The following screen appears, identifying the source and target disks.
4-8 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Managing RDR Disks
5. Click Finish.
The system mirrors the source disk to the target disk. The mirroring process may take a half-hour or more, depending on the size of the disks.
While the disks are resynchronizing, LEDs blink to indicate read and write operations, and ftSMC displays a value of OpState: State Syncing in the details pane for the disk.
To view the progress of the synchronization in ftSMC, expand Logical Disk
Information under ftServer, and select the virtual disk. In the details pane, the
progress is noted as a percentage, as follows:
Status: Resync: 20 percent
When the disks are synchronized, the LEDs on both disks are lit steady green and ftSMC displays a value of OpState: State: Duplex in the details pane for the disk and for the virtual disk. The value next to Status for the virtual disk is None.

the metadata. Be sure the disk has a minimum of 10MB free space.
A System Shutdown message may appear, stating that the system will reboot in two minutes. If the message appears, let the system restart.
N O T E S
1. If you added a system disk to an RDR virtual disk, a message notifies you that the system will reboot. The message gives you the option of confirming or cancelling the request.
2. The system restarts if you add a data disk to an RDR virtual disk and the software cannot unmount all data volumes on the disk.
3. You cannot add a physical disk to RDR if the disk is dynamic or a nonblank data disk.
Disk Failures During Resynchronization
In RDR resynchronization, partnered RDR virtual disks relate as source and target disks. The source is the disk from which the target disk is being resynchronized.
If a source disk fails or is removed from service during resynchronization, the target disk is removed from the system and treated as a deported disk. If the target disk fails or is removed from service during resynchronization, the source disk continues operating in simplex mode.
If the system starts to shut down while an RDR virtual disk is resynchronizing, RDR records the state of the resynchronization and, upon system reboot, resumes resynchronization from that point.
Write Caching
To optimize system performance, you can enable write caching on RDR virtual disks.
By default, write caching is disabled, except during disk resynchronization, when it is automatically enabled.
Write caching does not work on a simplex RDR virtual disk (except when it is resynchronizing), even if it is enabled. However, if you enable write caching on a simplex disk that is later duplexed, write caching will work.
To enable write caching

4. Check Enable write caching on the disk, and click OK.
Setting the Cache Flush Interval
The Set Cache Flush Interval command determines the interval at which the system deletes the unaccessed contents of the cache buffer on an RDR virtual disk.
To set the cache flush interval
1. In ftSMC, expand ftServer (Local) and click Logical Disk Information.
2. Right-click the desired RDR Virtual Disk and select Set Cache Flush Interval.
3. In the Cache Flush Interval field on the dialog box, enter the value (in minutes) of the interval and press Finish.
4. Click OK on the dialog box that indicates that the command was successfully

Read-load (LUN Load) Balancing
When you enable read-load (LUN load) balancing, read operations on duplex RDR virtual disks alternate between the two physical disks, which improves performance. By default, read-load balancing is enabled on all RDR physical disks.
You can enable or disable read-load balancing either
for each physical disk or globally
, for all RDR physical disks across the system.
To enable or disable read-load balancing for a single physical disk
1. In ftSMC, expand ftServer (Local) and Logical Disk Information.
2. Right-click the target RDR Virtual Disk.
3. Select Set Rdr Lun Load Balancing.
4. In the dialog box, set the Rdr Lun Load Balancing field to On or Off, and click

a particular RDR physical disk is set to Off, you must set it to On before a global load-balancing command can take effect on that disk.
Mirroring Dynamic Disks with RDR
This procedure explains how to turn dynamic disks into basic disks before mirroring them with RDR. To use RDR to mirror dynamic disks themselves, see Chapter 3 in the
Stratus ftServer System Software: Installation and Configuration for Windows
Systems (R002W).
Mirroring a dynamic disk with RDR involves two steps:
Converting a Dynamic Disk to a Basic Disk
!
C A U T I O N
Converting a dynamic disk to a basic disk removes all data from the disk. Before you convert the disk to a basic disk back it up so that you can recover the data.
1.
.
2. Expand Storage and click Disk Management.
3. Right-click the icon of the target disk in the lower portion of the Disk Management details pane.
4. Select Convert to Basic Disk.
5. If necessary, recover the information from backup media.
To upgrade the basic disks to RDR, see “Mirroring Disks Using RDR” on page 4-6 .
Setting the Active RDR Disk (Plex)
The Set As Active RDR Plex command makes the physical disk on which this command is issued the "active" disk. The active disk is the disk:
From which data is read
From which a partner disk is resynchronized
That survives a failover (the failure of one of two, duplex components)
To which the data traffic goes when disk utilities, like chkdsk, are run
4-12 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Managing RDR Disks
You might use Set As Active RDR Plex, for example, when using the chkdsk command to check the performance of a particular physical disk in an RDR virtual disk.
To do this, issue the Set As Active RDR Plex command for the physical disk you want to check; this makes it the active disk. Then disable read-load balancing on the RDR virtual disk, and run chkdsk on the active disk.
In the following procedure, n indicates a component number that appears in ftSMC.
1. In ftSMC, expand I/O Enclosure - 10 (or 11), Storage Enclosure - 40, Slot - n, and then right-click on Disk - n.
2. Select Set As Active RDR Plex.
A message reports that the operation was successful.
Deleting the RDR Configuration on a Physical Disk
Deleting the RDR configuration removes a physical disk from the RDR virtual disk. You delete one physical disk at a time.
After you delete the RDR configuration on a physical disk:
The RDR metadata is deleted, but other data remains on the disk.
The disk is no longer an RDR disk and is not part of an RDR virtual disk.
You can reconfigure the disk as an RDR disk again, using the Add Physical Disk
To RDR Virtual Disk command.
N O T E
If you delete the RDR configuration from a simplex data disk, then all the New Technology File System (NTFS) partitions on that data disk lose their drive letters.
You can delete the RDR configuration only from basic data disks, but not from simplexed or duplexed boot disks, dynamic disks, or data disks with one or more paging files.
To delete the RDR configuration on a physical disk
1. In ftSMC, expand I/O Enclosure - 10 (or 11), Storage Enclosure, Slot - n, and then right-click on Disk - n.
2. Select Delete RDR Configuration on Physical Disk for disk 0 (or 1 or 2).
3. Optionally, repeat steps 1 and 2 on the disk with which the deleted disk was mirrored.
When the second of the mirrored disks is removed from the RDR virtual disk, the
RDR virtual disk is removed.
Disk Storage Management
4-13
Managing RDR Disks
4. Repeat steps 1–3 for each physical disk to be removed.
N O T E
Disregard any “Unsafe Removal of Device” messages that appear when you remove an internal physical disk from the enclosure.
Changing Automount Behavior
After you use Delete RDR Configuration on Physical Disk on a Windows Server
2008 system, the target disk will appear with a new drive letter in the Windows Disk
Manager in Computer Management. This is because Windows Server 2008 uses automounting by default. (On a Windows Server 2003 system, the drive letter is simply deleted.)
To disable automounting in Windows Server 2008, so that it matches the behavior of
Windows Server 2003, open a command prompt and issue the following command:
mountvol /n
The change takes effect immediately.
To return the system to automounting, issue the following command:

The system does not warn you when you issue this command because the target disk has a surviving partner physical disk that still contains all of the data. For that reason, the system does not need to restart.
If you execute the Remove a Physical Disk from RDR Virtual Disk command on an unpartnered (simplex) RDR virtual disk (comprising one physical disk), the system

Managing RDR Disks
prompts you to remove all partition and volume data on the disk before the command can continue. The prompt alerts you that this operation may result in the loss of all data on this virtual disk since there is only one physical disk.
You cannot remove:
The only unmirrored boot disk
The only unmirrored disk containing a paging file
An unmirrored disk containing data
A resynchronizing disk
To remove a physical disk from an RDR virtual disk
1. In ftSMC, expand I/O Enclosure - 10 (or 11), Storage Enclosure, Slot - n, and then right-click on Disk - n.
2. Select Remove Physical Disk from RDR Virtual Disk.
Deporting a Physical Disk from an RDR Virtual Disk
Deporting a physical disk from an RDR virtual disk makes the deported disk a clone of its RDR virtual disk partner. You use the Deport Physical Disk from RDR Virtual Disk command to create backup disks and spare, bootable, RDR virtual disks.
Once a disk is deported, it is hidden from the system and is inaccessible from ftSMC.
It does not become accessible again until you remove it from and reinsert it into the system. You can physically remove and then reinsert the disk, or you can issue the
InitiateBringdown and InitiateBringup commands for the disk slot.
If you insert a disk deported from one system into another system, the disk appears in ftSMC as Active, Configured, Deported.
A deported disk inadvertently left in the system or reinserted into its original slot remains an intact backup. It is not automatically resynchronized or overwritten by the primary RDR virtual disk.
You cannot deport:
The last physical disk of an RDR virtual disk if it is bootable or contains a paging file
An unmirrored boot disk
A dynamic disk
A resynchronizing disk
The Deport a Physical Disk from an RDR Virtual Disk command should be grayed out if the physical disk is not in the valid state (for example, if it is a dynamic disk or a

simplex boot disk) for this command to work properly. A valid deport operation should rarely fail.
If the Deport a Physical Disk from an RDR Virtual Disk operation requires that the system reboot, a system-restart dialog box appears, giving you the option to restart the system immediately or later. If the operation succeeds without requiring a reboot, a message box indicating success appears.
If Deport a Physical Disk from an RDR Virtual Disk fails, a dialog box indicating the reason for the failure appears. In this case, the RDR virtual disk is not deported and the system does not reboot.
After a successful Deport a Physical Disk from an RDR Virtual Disk command, no drive letters or mount points associated with volumes on the deported disk are preserved.
To deport a physical disk from an RDR virtual disk
1. In ftSMC, expand I/O Enclosure - 10 (or 11), Storage Enclosure- 40, Slot - n, and then right-click on Disk - n.
2. Select Deport Physical Disk from RDR Virtual Disk.
A message reports that you may have to reboot the system if you continue with this command. You must restart only if the deport command fails. If it succeeds, a message reports the successful operation.
3. Click OK.
A message appears, telling you to remove the deported disk.
4. Remove the deported disk.
The deported disk disappears from ftSMC.
Creating a Spare Bootable RDR Disk
1. Be sure that the system (boot) disk is mirrored.
2.
that is the mirror of the system disk, as described in

Breaking a Physical Disk from an RDR Virtual Disk
The following procedure isolates an RDR virtual disk plex for backup, backs up the volumes, and then resynchronizes the broken plex with its original partner, adding it back to the RDR virtual disk.
You cannot perform this procedure on:
Dynamic disks
Simplex RDR virtual disks
RDR virtual disks while they are resynchronizing
RDR virtual disks if their verify interval is set to 0; that is, if RDR verify is disabled.
1.
Verify the RDR virtual disk that you are going to backup to ensure that both plexes
of the RDR virtual disk are healthy.
2. In ftSMC, expand I/O Enclosure, Storage Enclosure - 40, and then select Slot 1,
2, or 3 to access Disk 0, 1, or 2.
3. Right click on the target disk and select Break Physical Disk from RDR Virtual
Disk.
This command splits the plex from the RDR virtual disk, creates an exact copy of its volumes, and adds them to Disk Management.
4. Use backup software to make a copy of these volumes created in Disk
Management; then remove the volumes from Disk Management.
5. To add the removed plex back to the RDR virtual disk, in ftSMC, right-click the disk you broke in step 2, and select Add Physical Disk to RDR Virtual Disk. See
“Adding a Physical Disk to an RDR Virtual Disk” on page 4-7 for the procedure to
add a disk.
The plex is now synchronized with its active partner and is again a partner in an
RDR virtual disk.

Managing RDR Disks
Booting a System with a Backup RDR Boot Disk
1. Remove power from the system.
2. Remove all boot disks from the internal storage enclosure, if any are installed.
3. Insert the backup boot disk.
4. Press the system power button.
Reusing Data Disks
If you have stored a copy of a data disk that was created with RDR disk mirroring, use the following procedures to reuse the disk in the system.
Reusing a Stored-Data Disk
After you perform this procedure:
The data on the stored-data disk is overwritten with the data on the disk in its companion slot.
The stored-data disk remains an RDR disk.
To reuse a stored-data disk
1. Make sure the original partner of the stored disk is in the companion slot.
2. Insert the stored disk into its original slot. The system automatically resynchronizes the stored disk with the partner disk.
Wait for the disk to be fully resynchronized before removing the stored disk or before removing power from the system.
Removing the RDR Configuration from a Stored-Data Disk
This procedure removes the RDR configuration from a stored-data disk and deletes all of its data.
N O T E
To delete the RDR configuration from a stored-data disk
but retains its data, see “Deleting the RDR Configuration on a Physical Disk” on page 4-13 .
1. Make sure no disk occupies the slot that is the partner slot to the disk whose RDR configuration you are removing.
2. If your disk was a dynamic disk, use your disk-management tool to convert the disk to basic, deleting all data on the disk.
If your disk was a basic disk, use your disk-management tool to delete all volumes and partitions.
4-20 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Managing RDR Disks
3. In ftSMC, select and right-click the disk, and click Remove Physical Disk From
RDR Virtual Disk.
!
C A U T I O N
You must complete the final step. Otherwise, if the former
RDR virtual disk partner of the newly erased disk is inserted into the partner slot of the erased (but not deleted) disk, the newly inserted disk is mirrored to the empty disk, deleting the data on the newly inserted disk.
Resynchronizing RDR Disks
The system automatically resynchronizes disks that are reinserted into the system and
when I/O elements are returned to service. In addition, two explicit methods in ftSMC can initiate resynchronization of the physical disks of an RDR virtual disk:
Resynchronize This Physical Disk From RDR Virtual Disk . This command
resynchronizes the chosen physical disk with its with partner.
Resynchronize Physical Disks Of This RDR Virtual Disk . This command simply
makes the two physical disks of an RDR virtual disk identical. The software arbitrarily chooses which disk to make the master and which the copy, irrespective of which disk was last written to.
While the disks are resynchronizing, the disk LEDs blink to indicate read and write operations. You can also use ftSMC to monitor the status of the resynchronization process.
To monitor the status of the resynchronization process
1. In ftSMC, expand ftServer (Local), ftServer I/O Enclosures, and Logical Disk
Information.
2. Click one of the RDR Virtual Disk nodes.
3. Check the value of the Status property, which displays Resync nn% (where nn is the percentage completed) while the disk is resynchronizing.
When the resync process is finished, the Status value for the RDR virtual disk is None, and the LED on each physical disk in the RDR pair is lit steady green
When RDR disks are resynchronizing, the Logical to Physical Mapping details pane shows the disk that is resynchronizing as SYNCING, and shows the partner disk as
SIMPLEX

Resynchronizing a Backup Boot RDR Disk
To automatically resynchronize a partner RDR physical disk by insertion
1. Verify that the original partner disk of the backup boot disk is inserted into its original slot in the storage enclosure.
2. Reinsert the backup boot disk into its original slot in the storage enclosure.
The backup boot disk automatically resynchronizes with the original partner. The command takes some time to run.

Managing RDR Disks
Recovering and Replacing RDR Disks
In your disk-management tool, if the status of an RDR disk appears as Offline,
Missing, or Online (Errors), you can try to recover the disk manually. Verify that the
disk is securely seated in the enclosure and that it has power. Perform the following procedures to recover the disk.
To recover an RDR disk
1.
Delete the RDR configuration on the disk and then physically remove it from the
enclosure.
N O T E
Disregard any “Unsafe Removal of Device” messages that appear when you remove an internal physical disk from the enclosure.
2. Replace the defective disk and add the disk to an RDR virtual disk
.
In the unlikely event of a system failure resulting from disk failures, restore the system by performing one of the following procedures, as appropriate:
Restore the system by using a backup system disk. See the discussion of creating spare bootable hard disks in the Stratus ftServer System Software: Installation and
Configuration for Windows Systems (R002W) for information.
Reload the ftServer System Software, as described in the Stratus ftServer System
Software: Installation and Configuration for Windows Systems (R002W).
To replace a failed physical RDR disk
1. Remove the failed disk.
2. Insert a blank replacement disk.
Verifying RDR Disks
RDR disk verification verifies the integrity of RDR disk mirrors. Specifically, it:
1. Reads all sectors on both disks. If it detects a read error, it recovers the degraded sector from the good partner disk. This safeguards the integrity of both disks.
2. Compares the data from each sector on both disks. If it detects a discrepancy, it logs an error to the event log. In the unlikely event that this happens, contact the
CAC or your authorized Stratus service representative, or log an issue under their maintenance contract.
Disk Storage Management

2. Right-click the appropriate RDR virtual disk.
3. Select Verify RDR Virtual Disk.
A message appears, stating that the operation completed successfully .
To stop verifying an RDR disk
Use the following procedure to stop RDR verification.
1. In ftSMC, expand ftServer (Local) and click Logical Disk Information.
2. Right-click the appropriate RDR virtual disk.
3. Select Stop Verify RDR Virtual Disk.
A message appears, stating that the operation completed successfully .
To set the interval for automatic RDR disk verification
1. In ftSMC, expand ftServer Drivers, right-click SCSI Port Duplex
Driver - Sradisk_Driver, and select Properties.
2. In the dialog box, click the third Properties tab from the left.
3. Set the LunVerifyInterval property to the desired value and click OK.
The default value is 10080 minutes (7 days), meaning 10080 minutes from the time of the last verification command. The nonzero minimum value cannot be less than
60 minutes. A value of 0 disables automatic RDR disk verification.
Making Sure You Do Not Boot from a Stale Disk
If the system becomes powered off because power to both enclosures is lost, but not at the same time, RDR disks become unsynchronized. In this case, if you do not use care in rebooting the system, it can boot from a stale disk. If you experience such a power loss to the system, boot from the enclosure that was running most recently
(remove the power cord from the other enclosure, whose disks contain stale information). If you cannot be sure which enclosure to boot from, contact the Stratus
Customer Assistance Center (CAC) or your authorized Stratus service representative for help.
You may need to recover updated data if your applications start to run on a stale disk.
When you are sure that the system and data disks on the boot enclosure are updated, restore power to the second enclosure.

Using Volume Mirroring for Fault Tolerance
Configuring the Priority of RDR Virtual Disk Resynchronization
The resynchronization priority establishes the portion, expressed in megabytes per second (Mbps) in the details pane, of I/O bandwidth that is used for the RDR disk resynchronization operation.
To prioritize resynchronization for all RDR disks in the system
1. In ftSMC, expand ftServer Drivers, right-click SCSI Port Duplex
Driver - Sradisk_Driver, and select Properties.
2. In the dialog box, click the third Properties tab from the left.
3. Set GlobalResyncPriority to Low, Normal, or High and click OK.
To prioritize resynchronization for individual RDR disks
1. In ftSMC, expand the appropriate I/O Enclosure node and click Logical Disk
Information.
2. Right-click the target RDR virtual disk.
3. Select Set Resync Priority.
4. Select Low, Medium, or Normal and click OK.
Using Volume Mirroring for Fault Tolerance
You can use Windows Disk Management to mirror volumes on disks in internal storage subsystems.
When using Windows Disk Management to implement data fault tolerance, format volumes as NTFS volumes.
Configure disks as dynamic disks. Dynamic disks organize data within volumes on a disk and support fault-tolerant operation and disk migration between systems.
Mirror each volume (the boot volume on the system disk and all data volumes) on
Assign system disks and data disks to the same disk group.
!
C A U T I O N
Failure to set up your disk storage as required results in storage that is not fault tolerant.
A mirror is an identical copy of data that you can access if your primary data becomes unavailable. Stratus requires that you mirror the boot volume on the system disk. The resulting mirrored pair of disks work together to provide a fault-tolerant volume. If one disk fails, the volume automatically uses the data from the other disk.
Disk Storage Management
4-25
Using Volume Mirroring for Fault Tolerance
Mirror all data volumes. Mirroring volumes as documented provides fault tolerance, because volumes are mirrored on separate physical disks on separate FC buses.
When mirroring volumes, pair identical physical disks (same capacity, model, and manufacturer) so that in the event of a disk failure, an entire physical disk can be replaced without any data loss. See
“Mirroring Disks in ftScalable Storage Systems” on page 4-29 for details.
Mirrored Volume Resynchronization
When a volume is mirrored across two physical disks, and one of the disks fails or is brought offline for any reason, the remaining good disk continues to operate. However, the data on the mirrored volumes is no longer synchronized.
After a disk is replaced or brought back online, the mirror between it and the disk that remained in operation must be resynchronized. During resynchronization, the system copies the format and the contents of the good mirrored volume(s) to their mirror(s) on the disk most recently brought back online.
N O T E
Because mirror resynchronization can severely affect performance, you should resynchronize mirrors when the system is least busy.
Mirror resynchronization can occur automatically, or, in some cases, you must resynchronize the mirror manually:
If you insert a replacement disk without a disk signature into the same slot as the failed disk, the system automatically attempts to resynchronize the disk.
If you replace a failed disk with a blank basic or dynamic disk that contains a signature, you must resynchronize the disks manually.
The system automatically attempts to resynchronize the disks if:
– An I/O element is removed and inserted.
– An I/O element goes offline and returns online.
Volume Resynchronization After Rebooting
After rebooting the system, and depending on the circumstances under which the system was shut down, you may need to explicitly reactivate a failed mirrored partner to resynchronize a volume.
For example, if the system was shut down normally, but it was shut down while synchronization was in progress, you need to explicitly reactivate the mirror. On the
4-26 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Using Hardware RAID Controllers For Fault Tolerance
other hand, if the system shutdown was due to an unexpected event like a power failure, the disks begin the remirroring process automatically after booting.
Before mirroring system disks with a disk management tool, make sure either that both disks are plexes of an RDR virtual disk or that neither disk is. Do not partner RDR and non-RDR system disks in a mirror. Otherwise, the disks will fully resynchronize after every reboot.
The boot disks do not require resynchronization if the RDR disk is the primary boot volume from which the system is booted.
N O T E
You may remove disks from or insert disks into the internal storage as needed.
Using Hardware RAID Controllers For Fault Tolerance
Optional ftScalable Storage systems employ redundant hardware RAID controllers.
Fault-tolerant volumes reside on virtual disks configured in a supported RAID topology.
Use the embedded RAIDar graphical user interface to create and configure the virtual disks. You use Windows Disk Management to create the volumes. See the ftScalable
Storage: Getting Started Guide (R601) and the ftScalable Storage: Operation and
Maintenance Manual (R600) for information about how to create, configure, and monitor fault-tolerant disk resources on ftScalable Storage systems.

Finding an Internal Physical Disk
The information for non-RDR disks is the same, except that it does not include LUN
(RDR virtual disk) or PLEX (physical disk) information, which pertains only to RDR disks.
In the details pane:
Harddisk0
refers to the Windows disk name.
LUN1
refers to RDR virtual disk 1. The system assigns the LUN numbers dynamically. (An ftServer system can support a maximum of three RDR virtual disks.)
PLEX1
and PLEX2 refer to the two physical disks that together make up RDR virtual disk 1 (LUN 1).
Basic
refers to type of disk. The other possible value is Dynamic.
10/40/1
indicates the following:
– 10 indicates I/O element 10.
N O T E
In rack-mounted systems, I/O element 10 is in the top enclosure and I/O element 11 is in the bottom enclosure.
Pedestal systems are rotated 90 degrees clockwise
(viewed from the front), so that I/O element 11 is on the left side of the system and I/O element 10 is on the right side.
– 40 indicates the internal storage enclosure within the I/O element.
– 1 indicates the top disk slot in rack-mounted systems.
For RDR disks, Duplex indicates that the two physical disks of the RDR virtual disks are partnered. If the two physical disks were not partnered, the displayed value would be Simplex.
For non-RDR disks, the values in this position indicate the disk’s operating status.
RDR virtual disks also appear in ftSMC under the Logical Disk Information node. In this location, the details pane presents the location of the physical disks in the RDR virtual disk in these properties:
Disk Enclosure Slot: DevicePath[2]
Disk Enclosure Slot: DevicePath[1]
However, the DevicePathID property that appears at the top of the details pane, and which has a number like 39/7, does not indicate a hardware component and does not signify the physical disks’s location in the system; it merely identifies the virtual disk to system-management software.

MTBF Statistics
MTBF Statistics
The fault-tolerant services software automatically maintains mean-time-between-failure (MTBF) statistics for many system components.
Administrators can view this information in ftSMC and can reconfigure the MTBF parameters that affect how the fault-tolerant services respond to component problems.
The system stores the current MTBF values associated with each device in Windows registry keys. Whenever an MTBF value changes, the registry reflects the change.
Therefore, when the driver stops and restarts, or the system restarts, the system retains the current MTBF information.
For procedures explaining how to set these settings, see ftSMC Help.
Clearing the MTBF
Clearing the MTBF sets the MTBF to 0 (Unknown) and erases the record of all faults.
N O T E
Clearing the MTBF does not bring a device back into service automatically.
If the device that you cleared is in the Broken state, you must correct the state.
User actions that can cause a transition out of the Broken state include the Initiate
BringUp and Initiate BringDown actions and removing the board.
Changing the MTBF Threshold
The MTBF threshold is expressed in seconds. If a device’s MTBF falls beneath this threshold, the system takes the device out of service and changes the device state to
Broken.
!
C A U T I O N
Stratus presets the MTBF thresholds. Do not modify them unless instructed to do so by the CAC or your authorized
Stratus service representative.

Locating Components
Locating Components
ftSMC displays device IDs and device paths for system components that it monitors.
Component location diagrams show the device IDs of major elements, enclosures, and
internal disks. Two commands assist you in locating select system components:
Start Slot Identification. Causes the LEDs on the component to flash so that you
can physically locate it.
Stop Slot Identification. Stops the LEDs on the component from flashing after you
have physically located it.
CPU-I/O enclosures, PCI adapters, and modems support these slot identification commands.
Device IDs and Device Paths
Hardware components in the system inventory are organized hierarchically. Level 1 components (for example, CPU elements and I/O elements, represented by the
CPU Enclosure nodes and I/O Enclosure nodes, respectively) have Level 2 child components, such as DIMMs and processors, which may have Level 3 and Level 4 components.
Hardware devices in the system inventory have device ID numbers. For example, the
device ID of the ftScalable Storage subsystem in Figure 5-2
is 75. The figure illustrates the following hierarchically presented components and their device IDs:
Level 1: Storage Enclosures (the external storage subsystem)
Level 2: ftScalable Storage - 75
Level 3: ftScalable Storage Controller - 1
Figure 5-2. Component Levels
A device path is a slash-separated sequence of device IDs that identifies the location of a component in the system. Device paths appear in the details pane of ftSMC. They use the following syntax:

Remote service to your system by service support personnel
You use the ASM Web site to configure all remote event reporting and remote service features of the ASN. See the Stratus ActiveService Network Configuration
Guide (R072) for details.
Remote Reporting of Events
When the system’s fault-tolerant software detects a hardware or software problem, the
system generates alarm messages (also referred to as alerts) that can be:
Sent to the CAC or other authorized Stratus service representative
Sent to a customer contact by way of email
Written to the Windows system event log
Alarm Messages
Alarm messages placed in the system event log contain information about device state changes such as changing modes from duplex to simplex, failure of diagnostics on a device, exceeded thresholds, memory dumping, and failed device startups. Alarm messages appear with Stratus Alarms as the event source.
You can configure your system to send alarm messages by the following options:
Internet with phone line as backup
Phone line with Internet as backup
Phone line only

Determining the Value of the Send Alarms By Property
1. In ftSMC, expand ftServer (Local) and ftServer Configuration.
2. Click ActiveService Network.
3. In the details pane, check the value of the Send Alarms By property.
See the Stratus ftServer Systems: Technical Reference Guide (R550) for descriptions of the alarm messages.

Remote Event Notification and Service
Event Notification on Boot Failure
The VTM will send an alarm when a fault-resilient boot fails to bring up the Windows operating system.
N O T E
Starting with ftServer 2600, 4500, and 6300 systems,
VTM functionality is integrated into the baseboard management controller (BMC). In previous ftServer system models, the VTM and BMC were separate hardware components.
System Inventory Reports
An alarm message can include a full system inventory, a partial system inventory, or no inventory at all, depending on the message type. A system inventory consists of an enumeration of all of the properties of the manageable hardware devices tracked by the Inventory service.
Event-Log Entries
System software may generate an alarm in response to a sequence of several events.
To indicate what these events are, an alarm message may include event-log entries.
These event-log entries contain items that represent an event from both the system event logs (SELs) and application event logs (AELs). The number of event-log entries included with an alarm message is determined by specifying how many seconds of the event log to include. System software may configure this time differently for each type of alarm, or it may exclude some event-log entries.
The BMC on each CPU-I/O logs SELs for its CPU-I/O enclosure. The Windows System
Manager (WSM) reads the SELs from each BMC and saves them to the AELs. In the
AELs, the system events are simply interleaved with one another, not merged, so events reported on both enclosures appear in duplicate.
Remote Service
If you have a service contract with the CAC or your authorized Stratus service representative, your service representative can connect to your system through either the Internet or a phone line.
When the connection is through a phone line, the VTM validates that the phone call is from a permitted source, disconnects the incoming call, and calls back to make a connection to the validated CAC.
You can configure the system to allow the CAC or your authorized Stratus service representative to connect to your system through the Internet, using secure tunneling over IP, to diagnose problems and perform data-transfer functions. These accesses are subject to validation by the CAC database, by the VTM on your system, and by you

The CAC or your authorized Stratus service representative may contact you to determine the seriousness of the condition. If a CRU has failed, the CAC or your authorized Stratus service representative will ship a new part to your site.
System software continuously copies a limited number of Windows system event-log messages to a log on the BMC so that support personnel can retrieve the log if your system fails.
Making Dump Files
Dump files are snapshots of either a system’s memory or a particular component’s firmware memory. Dump files enable the CAC or your authorized Stratus service representative to diagnose system or component problems. You can create dump files in the following ways:
Configure your system
In ftSMC, right-click a CPU Enclosure, and select the Dump and Go command
In ftSMC, right-click a certain component, and select either the Dump and Go
command or the

Configuring System Memory Dumps
Memory dumps are enabled through the Board Instance driver’s DumpQuickEnabled and DumpNumberOfFilesToSave properties.
To enable system memory dumps
1. In ftSMC, expand ftServer (Local), ftServer Drivers, and then
Board Instance Driver - srabid.
2. Right click Board Instance Driver - srabid, select Properties, and set
DumpQuickEnabled to True.
3. Set DumpNumberOfFilesToSave to the number of dump files you want to save to disk.
Dump files beyond this number overwrite the existing saved dump files. For instance, if the value is 3, then the fourth saved dump file overwrites the first, existing dump file.
If, at the time of a system crash, the DumpQuickEnabled property of the Board
Instance Driver node is True and the CPU element is duplex, the system creates a
memory dump and stores the dump in the memory of one CPU element. The system restarts with the remaining CPU element. After the system restarts, the dump is automatically copied to a disk file.
After a system reboot where a dump has been generated, do not attempt to read or copy the Memory.dmp file created. After the system has completed writing the
Memory.dmp file, it renames the file Memoryn.dmp, where n is a numeral. You can read or copy the Memoryn.dmp file. It may take up to five minutes after the reboot to complete writing the Memory.dmp file before it is renamed and can be read.
!
C A U T I O N
If you attempt to read or copy the Memory.dmp file while the system is writing it, you may corrupt the file.
The normal Windows dump mechanism is used if the DumpQuickEnabled parameter is False (disabled) or if the CPU element is in simplex mode.
Dump and Go
The Dump and Go command captures a snapshot dump of a running system or a particular component without significantly interfering with the system’s or component’s operation. The system must be running duplex if you use this method.

Virtual LANs
Each network host in an IP multicast group uses the Internet Group Management
Protocol (IGMP) to acknowledge and maintain its IP multicast group membership with a switch.
In an Adapter Fault Tolerance (AFT), Switch Fault Tolerance (SFT), or Adaptive Load
Balancing (ALB) team, only one Ethernet PCI adapter (the primary adapter) is registered to receive IP multicast packets. When failover to another adapter occurs, the host cannot automatically update its multicast group membership using the new primary adapter; therefore, the host stops receiving multicast packets. If the switch is configured to periodically query the host for its registration, or if static IGMP is configured on the switch for each adapter in the team, multicasting to the host will eventually resume, but possibly after an extended interruption.
If you use IP multicasting, and you want to configure an AFT, SFT, or ALB team, you should test the team on site to verify if the behavior of IP multicasting after failover is acceptable. Alternatively, you can configure either static or dynamic link aggregation teams. IP multicasting functions more reliably with qualified switches that support these modes, because all Ethernet PCI adapters in a link aggregation team are registered to receive the IP multicast packets. The team continues to receive IP multicast packets unless all links to the switch are lost and then restored (in which case, there is also an extended interruption).
For more information about IP multicasting, see the documentation for your switch, or contact your network administrator.
Virtual LANs
You can add a Virtual LAN (VLAN) to any type of Ethernet team.
N O T E
Stratus supports VLANs only over Ethernet teams, not over individual adapters. An unteamed adapter is a single point of failure that can cause the loss of a network connection.
A VLAN allows you to isolate network traffic for a specific group of network hosts. Using
VLANs, you can organize networked systems into logical workgroups, such as
Marketing or Engineering, that span a building, complex, or an entire enterprise network. Members of a particular VLAN receive traffic only from other members of the same VLAN.
VLANs are particularly useful for limiting broadcast storms, reducing security problems, and simplifying network management.
B-4 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Configuring Ethernet Teams
There are two types of VLANs:
Implicit VLANs, which are configured entirely at the switch level. The switch does not alter or tag packets to enforce an implicit VLAN.
Explicit VLANs, which are configured throughout the network, on each adapter and link partner. Switches identify and route traffic based on a four-byte tag (802.3ac) in each packet header.
To support either type of VLAN, switches on your network must support 802.1Q
VLANs. Also, to configure a VLAN on your system, you need to contact your network administrator to obtain the VLAN ID for your workgroup, which must be identical to the
VLAN ID programmed into the switches.
In an environment with many VLAN workgroups, you can optionally implement the
Generic Attribute Registration Protocol (GARP) VLAN Registration Protocol (GVRP) to dynamically create, change, and remove VLANs. To support GVRP, all adapters and switches on your network must have GVRP enabled. For more information about
GVRP, follow the links in the online help available on the VLANs tab and the documentation for your switch, or contact your network administrator.
Configuring Ethernet Teams
Use the utilities embedded in Device Manager to configure Ethernet PCI adapters into teams. Keep the following notes, guidelines, and restrictions in mind when you create a team.
Each port on a dual-port Ethernet PCI adapter appears as a separate adapter in the Network adapters node of Device Manager.
Generally, assign Ethernet PCI adapters of only one media type (fiber optic or copper) to a team.
By default, speed and duplex are autonegotiated. Autonegotiation will result in incorrect duplex settings if one side of the link is set to autonegotiate and the other side of the link is not. Always confirm how the switch ports that will be connected to the network ports on the server are configured, and configure the network ports on the server the same way. Always use the same data rate and duplex mode values for all members of a team
There is no minimum or maximum number of teams to be configured; teams are limited only by the number of adapters available on your system and how you allocate them.
One team can have a maximum of eight Ethernet PCI adapters.
For fault tolerance, create teams that contain Ethernet PCI adapters from different
I/O elements. Only teams with Ethernet PCI adapters in different I/O elements are
Configuring And Managing Ethernet PCI Adapters

fault tolerant. (See
“Locating Ethernet PCI Adapters” on page B-6
for information about locating Ethernet PCI adapters.)
In addition, Stratus does not support the following:
Manipulation of adapter power management options.
Teaming third-party Ethernet PCI adapters with Stratus Ethernet PCI adapters.
Only Stratus Ethernet PCI adapters have been tested for compatibility and fault tolerance in ftServer systems.
To configure Ethernet PCI adapters into fault-tolerant teams, perform the procedures described in the following sections, in the order listed.

“Assigning an IP Address to a Team or VLAN” on page B-18
Locating Ethernet PCI Adapters
When you create a team of Ethernet PCI adapters, you must connect the team members to adapters located in different I/O elements or the team will not be fault-tolerant, since the failure of the team’s I/O element will cause both team members to fail.
To help you verify that you are selecting adapters located in different I/O elements, use the Identify Adapter command to flash a status LED in a specific Ethernet port so you can visually locate it.
N O T E
To determine which LED on the Ethernet port will flash, see the Stratus ftServer Systems: PCI Adapter
Guide (R461).
To locate an Ethernet PCI adapter port
1.
In the Network adapters node in Device Manager , right-click the target adapter and
select Properties.
2. Click the Link Speed tab and then Identify Adapter. The Identify Adapter dialog
shows an example.
B-6 Stratus ftServer System Administrator’s Guide for the Windows Operating System (R014W)
Figure B-1. Identify Adapter Dialog Box
Configuring Ethernet Teams
3. On the Identify Adapter dialog box, click Start.
The LED on the selected adapter will flash until you click Stop on the Identify
Adapter dialog box.
4. Find the Ethernet port with the flashing LED and make note of its device name in
Device Manager (for example, Stratus 82576 2-port Copper Gigabit Adapter).
5. When you have identified the adapter, click Stop and then Close on the Identify
Adapter dialog box.
Configuring Link Speed and Duplex Mode
By default, Ethernet ports on the U104 Dual-Port Fiber Gigabit Ethernet PCI-Express
Adapter, the U105 Dual-Port 10/100/1000 Base-T Ethernet PCI-Express Adapter, and the embedded Ethernet PCI adapters are configured to autonegotiate the best speed for a connection. On a network that operates at 10 or 100 megabits per second (Mbps), automatic settings can result in unreliable connections and inaccurate reporting of link activity and duplex mode. For reliable operation, manually configure the link speed and duplex mode for all Ethernet PCI adapters connected to networks that operate at 10 or
100 Mbps.
The term duplex in duplex mode is unrelated to the term duplexed used when referring to PCI adapters that are duplexed for fault-tolerance. Duplex mode refers to the ability of a communications line (which is attached to an Ethernet PCI adapter) to send and receive data simultaneously. In full-duplex mode, the line can send and receive data simultaneously. In half-duplex mode, the line can only send or receive data at any given
Configuring And Managing Ethernet PCI Adapters
B-7
Configuring Ethernet Teams
moment. Duplex mode does not refer to whether or not a PCI adapter is one of a pair, or is teamed, for fault-tolerance.
N O T E S
1. Ethernet adapters or ports that are connected to networks running at one gigabit per second (Gbps) rely on autonegotiation. Do not manually configure
1-Gbps operation.
2. ftServer systems support 1-Gbps line speed only in full-duplex mode.
!
C A U T I O N
When you manually set these values, make sure that the values are identical for the Ethernet port and the link partner to which it connects, and that the settings for all
Ethernet ports in one team are the same.
To set the link speed and duplex mode
1.
In the Network adapters node in Device Manager , right-click the target adapter (if
necessary, expand a team to access its member adapters) and select Properties.

“Updating a Team’s Ethernet Address” on page B-25
for more information.
2. Verify that an IP address has been assigned to each team or VLAN.
If you have created a team with VLANs, each VLAN in that team requires an IP address. (The team and the Ethernet PCI adapters in the team have no IP addresses.)
If you created a team without VLANs, the team is configured to obtain an IP address automatically.
If a team requires a static IP address, or if a team or VLAN does not have an IP
address, configure the IP address as described in “Assigning an IP Address to a

IP address, note the IP address of the team when you remove it. An assigned IP address is deleted when you remove the team.
To remove a team
1.
In the Network adapters node in Device Manager , right-click the target team and
select Uninstall.

Using Diagnostics
Using Diagnostics
You can run connection, link, cable, and hardware diagnostics on your system’s
Ethernet infrastructure.
Running hardware diagnostic tests on the primary adapter in an AFT or SFT team stops network traffic until the secondary PCI adapter takes over. Running hardware diagnostics on the secondary adapter could reduce throughput. Running hardware diagnostics on an unteamed PCI adapter stops network traffic during the entire test.
To start PROSet diagnostics
1.
In the Network adapters node in Device Manager , right-click the target adapter and
select Properties.
2. Select the Link Speed tab and click the Diagnostics button.
3. In the Diagnostics dialog box, click the Connection, Cable, or Hardware tab for the appropriate test (
4. Click Run Test. The test results are displayed in the Diagnostics dialog box.
N O T E
Do not run the Connection test on a teamed adapter. It may return a false error report about not having valid IP information.

If you experience persistent network connectivity problems, try replacing the associated Ethernet PCI adapter(s). If that does not correct the problem, contact your authorized Stratus service representative.
Using ftSMC to Check Network Statistics
You can find network statistics for unteamed adapters in ftSMC. The statistics are located in Performance Counters under the Ethernet Controller node.

Renaming Ethernet Teams
Renaming Ethernet Teams
When you create two or more teams on a new system or a system on which an IPL has just been performed, one of the teams may not have the name you assigned it. In the
PROSet utility, the team name appears to be set correctly, but in Windows Network
Connections, it is not the name you specified. Perform the following procedure to rename the incorrectly named team.
To rename a team
1.
In the Network adapters node in Device Manager,
right-click the target adapter and select Properties.
2. Select the Settings tab, click the Modify Team button and select the Name tab.
3. Enter the new team name in the Enter Team Name field and click OK. Click OK on the Settings tab.
The new name appears in the Device Manager under the Network adapters node.
