Operating Tips and Information
This section contains general information on operating the Enterprise Virtual
Array 3000. You should familiarize yourself with these topics before operating the storage system. Understanding these topics and following the recommended procedures will contribute to the successful and trouble-free operation of your storage system.
Minimum Disk Group Sizes
A disk group must contain no fewer than eight disks. The Command View EVA default is four disks. Do not use this default. You must specify a minimum of eight disks.
If you remove disks and the result is a disk group with fewer than eight disks, reduced functionality could result. If you discover a disk group with fewer than eight disks, restore the disks necessary so that the disk group has eight disks.
Contact your HP authorized service representative for assistance, if necessary.
Operating an HSV100 Controller at or Near Storage Limit
When operating the HSV100 controller at or near its available storage limit, use the high water threshold warnings to alert you when more storage must be added to the system.
Secure Path Version
The Enterprise Virtual Array 3000 should always be operated with the supported version of Secure Path. Supported versions of Secure Path are listed in the
Enterprise Virtual Array 3000 Release Notes.
Dynamic Volume Expansion
If you need to increase the capacity of an existing virtual disk, use dynamic volume expansion to increase the capacity. The host operating system must support dynamic volume expansion.
32
Enterprise Virtual Array 3000 User Guide
Storage System Description
Disk Resource Pending Timeout for Large Configurations

Host Information
Make a list of information for each host (computer) that will be accessing the storage system. You will need the following information for each host:
■
The LAN name of the host
■
■
A list of World Wide Names of the Fibre Channel adapters, also called host bus adapters, through which the host will connect to the fabric to access the storage system
IP address of each host
■
■
Operating system type
Available LUN numbers
Entering Data Using the OCP
During installation of the storage system, two values are entered using the OCP on one of the controllers:
■
WWN—Mandatory to complete setup.
■
Storage system password—An optional security measure, a password allows only specific instances of the Command View EVA management agent to access the storage system.
Setting Up the HSV100 Controllers Using the OCP
Fibre Channel protocol requires that each controller pair have a unique Node
WWN. A 16-character hexadecimal WWN is assigned to each storage system prior to shipment.
Note: A WWN is unique to a storage system and cannot be used for any other storage system or device on the network. Once a WWN is assigned to a controller, you cannot change the WWN while the controller is part of the same storage system. A replacement controller will inherit the WWN assigned to the storage system.

Introduction to Command View EVA
Command View EVA is the user interface through which you communicate with and manage an Enterprise Virtual Array 3000.
The Command View EVA software is installed on an HP OpenView Storage
Management Appliance and runs in the environment provided by the HP
OpenView Storage Management Appliance Software. When installed on the management appliance, the Command View EVA software creates a management agent, which communicates with the storage system.
The client of the management agent is a standard web browser. The relationship of
Command View EVA and a storage system is shown in
Command View EVA is launched from the Storage Management Appliance
Software interface.

Storage System Managed by Another Management Agent
A management agent can control multiple storage systems and multiple management agents can also control a single storage system. However, only one
agent is allowed to manage a storage system at a time. Password protection controls management agent access to storage systems. When multiple management agents reside on the same fabric, without password protection, any management agent on the fabric could access any storage systems on the fabric.
The display shown in
Figure 17 , appears if another management agent is detected.

Data Replication Groups
Hardware
All of these components are accessible using the folders in the Navigation pane, as
Figure 18: Storage system components
Virtual Disks
A virtual disk (Vdisk) is a virtualized disk drive created by the controllers as storage for one or more hosts. Virtual disk characteristics provide a specific combination of capacity, availability, performance, and accessibility. The controller pair manages virtual disk characteristics within the disk group specified for the virtual disk.
The host computer sees the virtual disk exactly like it would see a physical disk with the same characteristics.
60
Enterprise Virtual Array 3000 User Guide
Command View EVA
Note: The maximum number of virtual disks is 512. One virtual disk can be presented to multiple hosts. The maximum size of a virtual disk is 2047 GB. The maximum number of presentations is 8192.
There are three types of virtual disks:
■
Active member of a virtual disk family
— a virtual disk that is accessed by one or more hosts for storage. An active member of a virtual disk family is automatically created whenever a new virtual disk family is created. An active virtual disk member and its snapshot(s), if one or more exist, constitute a virtual disk family.
■
Snapshot virtual disk
— a virtual disk that reflects the contents of another virtual disk at a particular point in time. A snapshot operation can be done only to an active member of a virtual disk family. The active virtual disk member and its snapshots constitute a virtual disk family. A snapshot is intended to be temporary.
Note: A maximum of seven snapshots per virtual disk can exist at one time.
Business Copy EVA must be installed to enable the snapshot and Snapclone features of the storage system.
■
Virtual disk Snapclone
— a Virtually Instantaneous Snapclone is a virtual disk that is an exact copy of another virtual disk at a particular point in time. Only an active member of a virtual disk family can be snapcloned. The snapclone, like a snapshot, reflects the contents of the source virtual disk at a particular point in time. Unlike the snapshot, the snapclone is an actual clone of the source virtual disk and becomes an independent active virtual disk member of its own disk family when all the data is replicated. A snapclone can be presented to hosts and used for storage while the data is replicating.
Within the Virtual Disks folder in the Navigation pane are Vdisk families. You can click on any one of the Vdisk families within the virtual disk folder to see the properties page for a specific Vdisk family.
The Virtual Disks folder is accessible using the folder structure in the Navigation pane, as shown in
Enterprise Virtual Array 3000 User Guide

Figure 19: Virtual Disk folder
Presenting a Host
A host can be selected for presentation (that is, a virtual disk made available to a host). Two choices exist:
■
Select a host for presentation—indicates that the host can use the virtual disk for data storage. The host will see the virtual disk at the next available LUN.
■
Select a host and LUN for presentation—indicates that the host can use this virtual disk for data storage. The host will see the virtual disk at the specified
LUN.
Hosts
A host is a computer that operates applications relative to a storage system. A host uses one or more virtual disks created and presented by the controller pair. Each host connects to the fabric through one or more Fibre Channel adapters (FCAs).
An FCA is a hardware and firmware device that enables a host computer to use the
Fibre Channel transmission protocol. Each Fibre Channel port on a host adapter has a World Wide Name (WWN). Typically, the host operating system reports the
WWNs of all FCA ports in the host. The WWN also appears on a sticker on the
FCA board.
The Host folder is accessible using the folder structure in the Navigation pane, as

Command View EVA
Adding a Host
Before a host can use the storage system's virtual disks, the host must be known to the storage system. This process is called “adding a host.” Adding a host creates a path from the storage system to one host FCA port. Additional host FCA ports can be specified as a modification to the host properties.
Deleting a Host
Deleting a host removes it from the list of hosts that the storage system maintains.
You cannot delete a host if there are any virtual disks presented to it.
Modifying a Host
The following actions are available on the Host Properties page General tab:
■
■
■
Change the node name
Change the IP address
Change the operating system type
■
■
■
Move the host from its current folder to a different one
Enable or disable direct eventing
Delete a host
Note: The only changes that you can perform on an existing host are shown above. To specify any other property characteristics, you must delete the host, then add it again.
Using the Presentation Tab
Selecting the Presentation tab generates a display showing the Vdisks that have been presented to the selected host.
Working with Ports
The options available from the Host Properties page Ports tab let you add or delete adapter ports. To add a port:
1. Click Add Port on the Ports tab.
2. Select a World Wide Name from the drop-down list on the Add a Host Port page or enter the host port WWID manually.
3. Click Add Port.

Disk Groups
A disk group is the set or pool of physical disk drives in which a virtual disk is created. The physical disk is a disk drive that plugs into a drive bay and communicates to the controllers through the device-side Fibre Channel loops.
Only the controllers can communicate directly with the physical disks.
Collectively, the physical disks are called the array and constitute the storage pool from which the controllers create virtual disks. One controller pair can support up to 56 physical disks.
The following information is true about disk groups:
■
■
■
■
■
Each physical disk drive belongs to only one disk group.
Multiple virtual disks can be created in one disk group, up to the disk group's capacity.
Each virtual disk exists entirely within one disk group.
A disk group can contain all the physical disk drives in a controller pair's array or it may contain a subset of the array.
The minimum number of disks in a disk group is eight.
One disk group (the Default Disk Group) is created when the system is initialized.
Disk groups can be added, as needed, up to a maximum of 16.
The Default Disk Group is accessible using the folder structure in the Navigation pane, as shown in
Figure 22: Top level disk group
Enterprise Virtual Array 3000 User Guide
65
Command View EVA
Selecting a disk group within the disk groups folder in the Navigation pane displays the Disk Group Properties page, as shown in
Figure 23: Disk Group Properties page
Working with Disk Groups
The following operations can be performed on a disk group:
■
Creating a disk group
— combines physical disk drives into one disk group.
The system automatically selects drives based on their physical locations.
■
■
Modifying a disk group
— changes disk group properties, including the disk failure protection level, occupancy alarm level, disk group name, or comments.
Adding a new disk to a disk group
— adds a new physical disk to a disk group.
■
Deleting a disk group
— frees all physical drives contained in that disk group.

You cannot delete the only disk group (such as the default disk group). The Delete button is not visible if only one disk group is present.
For more information about disk drives, see “ Fibre Channel Disk Drives ” on page 81.
Data Replication
If Continuous Access EVA is installed, Command View EVA provides host-independent data replication across two or more Enterprise Virtual Arrays.
The storage systems can be located at the same physical site or different physical sites. When the storage systems are located at different sites, Command View
EVA provides a disaster tolerant storage and data replication solution.
Command View EVA manages data replication functions by organizing Vdisks into data replication (DR) groups. DR groups allow you to manage the replication of a set of Vdisks. The Data Replication folder is accessible using the folder structure in the Navigation pane, as shown in
You can perform the following data replication tasks:
■
■
■
■
Add a Vdisk to a DR group
— add the selected destination Vdisk family to the
DR group.
Create a DR group
— create up to 64 DR groups in a storage system.
Fail over a DR group
— when a failure occurs in your source storage system, data fails over to the destination storage system to allow continued access.
Modify a DR group
— modify the name and failsafe properties of a DR group.
■
Delete a DR group
— delete a DR group from a source storage system.

Two types of hardware enclosures exist for the Enterprise Virtual Array, disk enclosures and controller enclosures.
■
Disk enclosure—a disk enclosure contains up to 14 physical disk drives and
their supporting structures. Each of the vertical positions in the enclosure
where the disk drive is located is called a bay. The bays are numbered sequentially in decimal numbers, starting at the left when you are facing the front of the rack.

■
Controller enclosure—a controller enclosure is the mechanical enclosure that
protects the controller circuit board and its associated components for a controller pair. Except for the cache batteries and blower assemblies, all
components in the controller enclosure are considered one assembly and must not be separated.
The disk enclosure object is accessible using the folder structure in the Navigation pane, as shown in

I/O Module Power
The I/O module +5 VDC power sensing device protects the modules against overcurrent conditions. If the +5 VDC current exceeds 2.5 A rms (nominal), the sensor opens, removing the +5 VDC input from the I/O module, thereby disabling the module until:
■
The defective I/O module is replaced.
■
The overcurrent condition no longer exists.
Note: A disabled I/O module cannot transfer data and disconnects all the drives in the enclosure from the loop.
Copper Fibre Channel Cables
Copper Fibre Channel cables are used to connect the drive enclosures to each other, and to the controller enclosures. The cables are available in 0.6-meter and
2.0-meter lengths. Copper cables provide performance comparable to fiber optic cables.
Fibre Channel Disk Drives
HP disk drives are hot-pluggable and include the following features:
■
■
Dual-ported 2 Gbps FC-AL interface that allows up to 120 drives to be supported per FC-AL pair. Only 56 drives are supported on the Enterprise
Virtual Array 3000.
A variety of capacities and spindle speeds:
— 36 GB, 10K and 15K rpm

CXO6695A
Figure 36: Fibre Channel disk drive
The HP supplied disk drives conform to the enclosure initiated Enclosure Services
Interface (ESI).
Caution: Controlling air flow within the enclosure requires installing a drive or a drive blank in each drive bay. To avoid overheating, never remove more than one drive or drive blank from an operating enclosure at the same time. To prevent overheating and ensure proper operation, HP recommends installing a drive of equal or greater capacity, or a drive blank, as soon as possible.
Drive Status Reporting
The three status icons on the front of each drive define the drive operational status.

Drive Power
The drive voltage backplane sensors (+5.1 VDC and +12.1 VDC) can detect a drive overcurrent condition. When a drive overcurrent condition exists, the sensor disconnects the voltage from the drive to prevent writing data to the drive. The drive is disabled until one of the following conditions occurs:
■
The defective drive is replaced.
■
The overcurrent condition no longer exists.
Drive Blank
To maintain the proper enclosure air flow, you must have a drive or a drive blank in each drive bay. The function of the drive blanks is to control air flow within a bay. See
CXO6824A
Figure 38: Drive blank
Replacing a Disk Drive or Drive Blank
To replace a disk, you must complete the procedures outlined in “ Customer
Replaceable Units ” on page 195.
The disk replacement kit contains detailed replacement instructions.

Enclosure Power
The two power supplies mount in the rear of the enclosure. The supplies are auto-ranging and operate on a country-specific AC input voltage of
202 to 240 VAC ±10%, 50 to 60 Hz, ±5%, (188 to 264 VAC, 47 to 63 Hz).
The DC outputs of this power supply are:
■
+5.1 VDC for the EMU, I/O module, backplane, and drives
■
■
+12.1 VDC for the drives
+12.5 VDC for the blower
86
Enterprise Virtual Array 3000 User Guide
Storage System Hardware Components
Temperature Sensing
The power supply temperature sensor provides a temperature range signal to the
EMU. The EMU uses this signal to set the blower speed.
The power supply internal temperature can also set the speed of the blower. The higher the power supply temperature, the faster the speed of the blower. Should the power supply temperature exceed a preset value, the power supply automatically shuts down.
Blowers
The nominal output of each power supply is 499 W, with a peak output of 681 W.
A single power supply can support an enclosure with a full complement of disks, blowers, EMU, and I/O module.
The power supply circuitry provides protection against:
■
Overloads
■
■
Short circuits
Overheating
Power supply status and diagnostic information is reported to the EMU with voltage, current, and temperature signals.
See “ Regulatory Notices and Specifications ” on page 139 for the enclosure power
specifications.
The blower mounts on the rear of the power supply. A power supply connector is the interface between the blower and the enclosure for:
■
Speed control to the blower
■
■
Blower speed to the EMU through the power supply
Power supply high speed enable
■
Blower operating voltage
The power-supply-mounted blowers cool the enclosure by circulating air through the enclosure and the elements. The rate at which air moves (the air flow) determines the amount of cooling and is a function of blower speed (rpm). These blowers, under the control of the EMU or the associated power supply, can operate at multiple speeds. This ensures that when the enclosure temperature changes the blowers can automatically adjust the air flow.
Enterprise Virtual Array 3000 User Guide
87
Storage System Hardware Components
Should a blower be operating too slowly or stopped (a “blower failure”), internal circuitry automatically causes the remaining operational blower to operate at a higher speed. Simultaneously, the error condition is reported in several ways, including the power supply LED, the audible alarm, the enclosure fault LEDs, and the EMU alphanumeric display.
Should both blowers fail, the power supplies automatically shutdown.
Note: The failure of a power supply +12.5 VDC circuit disables the associated blower.
Power Supply and Blower Status Reporting
The green status LED on the blower displays the status of both the power supply
for definitions of the LED displays.

Description
Both the power supply and the blower are operational.

The power supply or the blower is nonoperational. When there is a blower problem, the other blower runs at a higher speed.
Recommended corrective actions:
1. Check blower for proper operation. Replace if defective.
2. Check power supplies for proper operation. Replace if defective.
Drive Enclosure EMU
The EMU provides increased protection against catastrophic failures. The EMU communicates with the HSV Controller to detect conditions such as failed power supplies, failed blowers, elevated temperatures, and external air sense faults.
The EMU for Fibre Channel-Arbitrated Loop (FC-AL) drive enclosures is fully compliant with SCSI-3 Enclosure Services (SES), and mounts in the left rear bay of a drive enclosure. See

Using the Enclosure Number Feature
This section provides a general description of the purpose, function, and operation of the EMU enclosure number (En) feature.
En Description
In a single rack configuration, the En is a decimal number in the range 00 through
14, which is automatically assigned by the enclosure address bus.
By default, the two-character alphanumeric display shows this number. Pressing the bottom pushbutton changes the display to En, the En display mode.
When the display is En, pressing and releasing the top pushbutton displays the En.
A display of 00 indicates that the enclosure is not connected to the enclosure address bus. When this condition exists, there is no EMU-to-EMU communication over the enclosure address bus.
A display of 01 through 14 indicates that the enclosure is physically connected to the enclosure address bus and can exchange information with other enclosures on the enclosure address bus. The decimal number indicates the physical position of the enclosure in relation to the bottom of the rack.
■
■
01 is the address of the enclosure connected to the bottom connector in the first (bottom) junction box (JB).
14 is the address of the enclosure closest to end of the bus, the top connector in the last (upper) JB.
Note: The enclosure address bus connection determines the display is a decimal number in the range
En
. For a single rack, the
You can only display, never change the

En
value.
Unless there is an error condition, the display automatically returns to the En
(01 through 14) one minute after a pushbutton was last pressed.
Enclosure Address Bus
The enclosure address bus is composed of cables and junctions boxes (JBs) that interconnect the drive enclosures and controller enclosures to provide a means for managing and reporting status and environmental conditions within the cabinet.
Each EMU collects data for its associated enclosure. The various address bus
components are shown in Figure 44 .
Enterprise Virtual Array 3000 User Guide
99
Storage System Hardware Components
Connecting the enclosures to the cabinet JBs establishes the enclosure address bus. The enclosures are automatically numbered, based on their physical distance from the bottom terminator.
The drive enclosure numbers are always assigned by the enclosure address bus.
Connecting the EMU CAB ONLY connector to a enclosure address bus JB automatically establishes an En of 01 through 14. Any drive enclosure not connected to the enclosure address bus is assigned an En of 00.

Error Condition Reporting
The EMU constantly monitors enclosure and element operation and notifies you of conditions that could affect operation. When an error condition is detected, the following action is taken:
■
The EMU alphanumeric display is changed to Er. A condition report has precedence over all other displays.
■
■
■
The audible alarm sounds (if it is not disabled).
The error is stored in the error queue.
The error is passed to the controllers for processing and display by Command
View EVA.
Enterprise Virtual Array 3000 User Guide

Storage System Hardware Components
Note: An error always generates a condition report. Not all condition reports are generated by errors.
The condition types, condition reports, and the interaction between conditions are
Error Condition Types
Each error condition is assigned to a category based on its impact on the disk enclosure operation. The error condition types include the following:
■
Unrecoverable condition
■
■
■
Critical condition
Noncritical condition
Information condition
UNRECOVERABLE Condition
This is the most severe condition. The condition occurs when one or more enclosure elements have failed and have disabled some enclosure functions. The enclosure may be incapable of correcting, or bypassing the failure, and requires repairs to correct the error.
Note: To maintain data integrity, corrective action should be implemented for an UNRECOVERABLE condition.
immediately
Reporting Characteristics
■
An UNREVCOVERABLE condition has precedence over all other condition.
■
The audible alarm is on continuously, as shown in Table 20 on page 96.
CRITICAL Condition
A CRITICAL condition is less severe than an UNRECOVERABLE condition.
This condition occurs when one or more elements inside the enclosure have failed or are operating outside of their specifications. The failure of the element makes continued normal operation of at least some elements in the enclosure impossible.
Other elements within the enclosure may be able to continue normal operations.
102
Enterprise Virtual Array 3000 User Guide
Storage System Hardware Components
Prompt corrective action should be taken to prevent system degradation.
Reporting Characteristics
■
An UNRECOVERABLE condition has precedence over a CRITICAL condition.
■
A CRITICAL condition has precedence over NONCRITICAL and
INFORMATION conditions.
■
When a CRITICAL condition is the most severe active condition, the audible alarm sounds three times per alarm cycle, as shown in
NONCRITICAL Condition
A NONCRITICAL condition is less severe than an UNRECOVERABLE condition or a CRITICAL condition. This condition occurs when one or more elements inside the enclosure have failed or are operating outside of their specifications. The failure of these elements do not affect continued normal operation of the enclosure. All devices in the enclosure continue to operate according to their specifications. The ability of the devices to operate correctly may be reduced should other errors occur.
Prompt corrective action should be taken to prevent system degradation.
Reporting Characteristics
■
UNRECOVERABLE and CRITICAL conditions have precedence over a
NONCRITICAL condition.
■
■
A NONCRITICAL condition has precedence over INFORMATION condition.
When a NONCRITICAL condition is the most severe error active, the audible
alarm sounds two times per alarm cycle, as shown in Table 20 on page 96.
INFORMATION Condition
This condition indicates a condition exists that does not reduce the capability of an element. However, the condition can become an error and require corrective action. In effect, an INFORMATION condition provides an early warning, which enables you to prepare to implement corrective action before an element fails.
Correction of the reported problem may be delayed.
Enterprise Virtual Array 3000 User Guide
103
Storage System Hardware Components
Reporting Characteristics
■
An INFORMATION condition is the least severe of all the condition reports.
■
When only an INFORMATION condition is active, the audible alarm sounds
once per alarm cycle as shown in Table 20 on page 96.
Error Queue
The EMU maintains an internal error queue for storing error conditions. Each error condition remains in the error queue until the problem is corrected, or for at least 15 seconds after the error is reported. This ensures that when there are multiple errors or a recurring error, each can be displayed. Each entry in the error queue can be displayed using a combination of the top and bottom pushbuttons.
Each error entry in the queue contains the element type, the element number, and the error code.
Correcting the error removes the associated condition from the error queue.
Replacing the EMU will also clear the error conditions.
The order in which the EMU displays the error queue information is based on two factors:
■
The severity of the error
■
The time the error occurred
The most severe error in the queue always has precedence, regardless of how long less severe errors have been in the queue. This ensures that the most severe errors are displayed immediately.
Note: When viewing an error, the occurrence of a more severe error takes precedence and the display changes to the most severe error.
The earliest reported condition within an error type has precedence over errors reported later. For example, if errors at all levels have occurred, the EMU displays them as follows:
1. UNRECOVERABLE errors in the sequence they occurred.
2. CRITICAL errors in the sequence they occurred.
3. NONCRITICAL errors in the sequence they occurred.
4. INFORMATION conditions in the sequence they occurred.
104
Enterprise Virtual Array 3000 User Guide
Storage System Hardware Components
Error Condition Report Format
Each EMU detected condition generates a condition report containing three pieces of information.
■
Element Type
The first two-digit hexadecimal display defines the element type reporting the problem. The format for this display is e.t. with a period after each character.
0.1. through F.F. are valid element types.
■
■
Element Number
The second display is a two-digit decimal number that defines the specific element reporting the problem. The format for this display is en. with a period after the second character.
Error Code
The third display is a two-digit decimal number that defines the specific error code. The format for this display is ec without any periods.
For detailed information about each condition report, including recommended
corrective actions, see “ EMU Generated Condition Reports” on page 161 .
Navigating the Error Condition Display
When an error condition occurs, the alphanumeric display changes to Er and the error menu is active. The pushbuttons are used to display the error condition values.
Perform the following procedure to display error conditions.
illustrates the sequence for displaying error conditions.
1. With Er in the display, press and hold the top pushbutton until the first element type is displayed. The most severe error in the queue will be displayed.
2. Release the top pushbutton when the element type is displayed. The element type has both decimal points lit.
3. Press and release the top pushbutton to display the element number. This display has only the right decimal point lit.
4. Press and release the top pushbutton again to display the error code. This display has no decimal points lit. Repeated press/release operations will cycle through these three values.

Storage System Hardware Components
Reporting Group Feature
Another function of the enclosure address bus is to establish reporting groups.
Because multiple storage systems can be connected to the same enclosure address bus, reporting groups are used to isolate the communication between storage systems. A component can only communicate with other components within its reporting group.
A reporting group (rG) is an HSV100 controller pair and the associated drive enclosures. The controller pair automatically assigns a unique (decimal) four-digit
Reporting Group Number (RGN) to each EMU on an FC-AL.
Each of the drive enclosures on a loop pair are in one reporting group. All of the drive enclosures on loop pair 1, both loop 1A and loop 1B, share a common reporting group number.
Each EMU collects environmental information from its disk enclosure and broadcasts the information to reporting group members using the enclosure address bus. Information from enclosures in other reporting groups is ignored.
Reporting Group Numbers
The reporting group number (RGN) range is decimal values 0000 through 4099:
■
0000 is reserved for enclosures that are not part of any reporting group, a
JBOD configuration.
■
■
■
0001 through 0015 are RGNs reserved for use by the EMU. When you enter them, they default to 0000.
0016 through 4095 are valid RGNs.
4096 through 4099 are invalid RGNs. When you enter them, they default to
4095.
The reporting group numbers are displayed on the EMU alphanumeric display as a pair of two-digit displays. These two displays are identified as rH and rL.
■
Valid rH displays are in the range 00 through 40, and represent the high-order
(most significant) two-digits of the RGN.
■
Valid rL displays are in the range 00 through 99, and represent the low-order
(least significant) two-digits of the RGN.
Viewing Reporting Group Number
Perform the following procedure to view a reporting group number:
1. Press and release the bottom pushbutton until the alphanumeric display is rG.
2. Press and hold the top pushbutton unit the display is rH.
Enterprise Virtual Array 3000 User Guide
107
Storage System Hardware Components
3. Press and release the top pushbutton to display the first two-digits of the RGN.
4. Press and release the top pushbutton until the alphanumeric display is rH.
5. Press and hold the top pushbutton until the alphanumeric display is rL.
6. Press and release the top pushbutton to display the last two digits of the RGN.
7. To exit the display, press and release the bottom pushbutton until the alphanumeric display is rG.
Verifying Enclosure Operation
All the elements in the enclosure begin operating when power is applied. Check
the enclosure status LEDs in the front, lower right corner. See Figure 47
. If the display is not exactly as shown, an error condition exists. To determine the defective element, check the drive status LEDs on the front, the EMU, the power supplies, and the blowers, as well as checking the I/O module status LEDs on the rear. See

High Availability Features
Two interconnected HSV100 controllers ensure that the failure of a controller element (such as transceiver, cable, Fibre Channel port, and so forth) does not disable the system. The complete data redundancy includes two Loop A data paths.
A single controller can fully support an entire system until the defective controller, or controller element, is repaired.
If a blower or power supply fails, it can be replaced without shutting down the system.
Each controller has two lead-acid cache battery assemblies that provide power to the cache memory dual in-line memory modules (DIMMs). Each battery assembly has three lead-acid, nonspillable cells. When both battery assemblies are
fully charged, they can provide power to the DIMMs for up to 96 hours.

Storage System Racks
All Enterprise Virtual Array 3000 components are mounted in the storage system rack. The available racks are the Enterprise Racks and the Rack System/E racks.
The rack configuration is determined by the number of disk enclosures being used. Multiple storage systems can be installed in a single rack. For more information about storage system racks and configuration information, including expansion and interconnection, refer to the HP StorageWorks Enterprise Virtual
Array Hardware Configuration Guide.
Power Distribution
The power distribution components differ between the Enterprise racks and the
Rack System/E racks. See “ Enterprise Racks Power Distribution Components ” on page 129 or “
Rack System/E Power Distribution Components ” on page 133.
For either rack, the characteristics of the full redundant rack power configuration are as follows:
■
Each PDU is connected to a separate circuit-breaker-protected, 30-A AC site power source (220–240 VAC ±10%, 50 or 60 Hz, ±5%).
illustrates the compatible 60-Hz and 50-Hz wall receptacles.

CXO5409B
IEC 309 receptacle, 3-wire, 30-A, 50-Hz
Note: If local regulations forbid use of these receptacles, you must change the connectors on the PDU power cords.
■
The standard power configuration for the storage system rack is a fully redundant configuration. Implementing this configuration requires:
— Separate circuit-breaker-protected, 30-A site power sources with a compatible wall receptacle. See
.
Enterprise Virtual Array 3000 User Guide
Storage System Hardware Components
— The rack PDUs are connected to different wall receptacles.
— The drive enclosure power supplies on the left (PS 1) connect to a power source (PDM or PDU) on the left with a gray power cord.
— The drive enclosure power supplies on the right (PS 2) connect to a power source on the right with a black power cord.
— Each controller enclosure connects to a power source on the left with a gray power cord and to a power source on the right with a black power cord
.
The configuration provides complete power redundancy and eliminates all single points of failure for both the AC and DC power distribution.
Enterprise Racks Power Distribution Components
AC power is distributed to an Enterprise rack through a dual Power Distribution
Unit (PDU) assembly mounted at the bottom rear of the rack. Each Enterprise rack has either a 50- or 60-Hz, dual PDU mounted at the bottom rear of the rack.
Note: The major difference between the two PDU types is the cable power connector.
■
The standard 50-Hz PDU cable has an IEC 309, 3-wire, 30-A, 50-Hz connector.
■
The standard 60-Hz PDU cable has a NEMA L6-30P, 3-wire, 30-A, 60-Hz connector.
If these connectors are not compatible with the site power distribution, you must replace the PDU power cord cable connector.
Each of the PDU power cables has an AC power source specific connector. The circuit-breaker-controlled PDU outputs are routed to a group of four AC receptacles. See
Figure 56 . The voltages are then routed to PDMs, sometimes
referred to as AC power strips, mounted on the two vertical rails in the rear of the rack

PDMs
There are eight PDMs mounted in the rear of each rack:
■
Four mounted on the left vertical rail connect to PDU 1.
■
Four mounted on the right vertical rail connected to PDU 2.
Each PDM has six AC receptacles and two thermal circuit breakers. See
. The PDMs distribute the AC power from the PDUs to the enclosures.
Two power sources exist for each controller pair and drive enclosure. If a PDU fails, the system will remain operational.
Caution: The AC power distribution within a rack ensures a balanced load to each PDU and reduces the possibility of an overload condition. Changing the cabling to or from a PDM could cause an overload condition. HP supports only the AC power distributions defined in this user guide.

Moving and Stabilizing a Rack
WARNING: The physical size and weight of the rack requires a minimum of two people to move. If one person tries to move the rack, injury may occur.
To ensure stability of the rack, always push on the lower half of the rack. Be especially careful when moving the rack over any bump (for example: door sills, ramp edges, carpet edges, or elevator openings). When the rack is moved over a bump, there is a potential for it to tip over.
Moving the rack requires a clear, uncarpeted pathway that is at least
80 mm (30 in) wide for the 60.3 cm (23.7 in) wide, 42U rack. A vertical clearance of 203.2 cm (80 in) should ensure sufficient clearance for the 200 cm (78.7 in) high, 42U rack.
Caution: Ensure that no vertical or horizontal restrictions exist that would prevent rack movement without damaging the rack.
Make sure that all four leveler feet are in the fully raised position. This process will ensure that the casters support the rack weight and the feet do not impede movement.
The floor space requirements for a rack with a single-piece rear door are shown in
. The floor space requirements for a rack with a split rear door are shown in
Figure 62 . The split rear door is available on Enterprise Racks.
Each storage system rack has four feet and four casters. Raising the adjustable feet places the rack weight on the casters, so you can easily move the rack. Lowering the feet places the rack weight on the feet and prevents the rack from moving. The removable front and rear doors, and the removable side panels provide easy access to the rack interior.

This appendix provides a description of the EMU generated condition reports that contain the following information:
■
■
■
■
Element type (et), a hexadecimal number in the range 01 through FF.
Element number (en), a decimal number in the range 00 through 99 that defines a probable cause of the problem.
Error code (ec), a decimal number in the range 00 through 99.
The recommended corrective action.
The following topics are included in this appendix:

Note: The conventions used to differentiate between the elements of the condition report are:
■
■
■
The element type has a period after each character.
The element number has a period after the second character.
The error code has no periods.
The EMU can send error messages to the controller for transmission to the
Command View EVA graphical user interface (GUI). The messages displayed are specific to Command View EVA and are not within the scope of this publication.
This appendix explains the condition report format, correcting problems, and how to identify element types. The error codes are arranged in element type sequence
(that is, 0.1., 0.2., 0.3., etc.).

EMU Generated Condition Reports
Condition Report Format
When the EMU alphanumeric display is Er, there are additional displays that identify the element type, the specific element, and the error code, which defines the possible cause of the problem.
■
■
■
The first-level display defines the type of element affected with two alphanumeric characters separated by periods such as 0.1., 0.2., 1.3., F.F., and so forth. A disk drive problem would display an element type number of 0.1.
The second-level display defines the element affected with a two-digit, decimal number followed by a period. For example, when a bay 6 drive error occurs, the element number display is 06.; a display of 14. indicates a bay 14 problem.
The third-level display defines a specific problem, the error code with a two-digit, decimal number. For example, should the problem be either the installation of an incorrectly configured drive or one that cannot operate at the loop link rate, the display is 01.

Drive Conditions
The format of a disk drive condition report is 0.1.en.ec, where:
■
0.1. is the disk drive element type number
■
en. is the two-character disk drive element
Enterprise Virtual Array 3000 User Guide
163
EMU Generated Condition Reports
■
ec is the error code
A direct correlation exists between the disk drive element number and the bay number. However, no direct correlation exists between the disk drive bay number and the device FC-AL physical address. The FC-AL physical address is assigned by negotiation during system initialization.
The following sections define the disk drive error codes.
0.1.en.01 CRITICAL Condition
—
Drive Configuration, or Drive Link Rate
As each drive spins up and comes on-line, the EMU determines if the drive is
Fibre Channel compatible and can operate at the link rate (1 Gbps or 2 Gbps) established by the I/O module. If either of these conditions are not met, the EMU issues the condition report 0.1.en.01.
The corrective actions for these conditions are:
■
When the drive is not Fibre-Channel-compatible you must install a Fibre
Channel compatible drive or a drive blank.
■
When the drive is Fibre-Channel-compatible, the EMU compares the drive link rate with the I/O module link rate, the loop link rate.
If the EMU cannot determine the drive link rate, the EMU activates the drive bypass function for 1 minute. During this time the EMU continually checks the drive to determine the link rate.
■
If the EMU determines the drive cannot operate at the Fibre Channel link rate set by the I/O module, the drive bypass function ends and the drive is placed on the loop. This does not generate a condition report.
■
■
The EMU issues the condition report 0.1.en.01 when the drive link rate is incompatible with Fibre Channel link rate.
When the EMU cannot determine drive link rate during the 1-minute drive bypass time, the EMU places the drive on the loop. This process allows the drive to negotiate for an address.
— If negotiation indicates the link rates are compatible, the EMU rechecks the drive link rate to verify compatibility.
— If negotiation indicates the link rates are incompatible, an error condition exists and drive loop data transfers stop.
This condition report remains active until the problem is corrected. The problem affects disk drive en. Therefore, correction to prevent the possible failure of other elements is not required.

Note: The following restriction applies to all currently available versions of VCS.
Drive insertion refers to physically inserting drives into drive enclosure slots. It is not synonymous with drive addition to a disk group.
When inserting more than four disk drives into an operating storage system, the disk drives must be inserted in sets of four or fewer drives using the following procedure. This procedure must be followed to avoid unexpected storage system behavior.
1. Insert one to four disk drives into the storage system drive enclosure(s).
Ensure that each drive is fully seated and the locking mechanism is fully engaged.
2. Wait until the activity light (down arrow) on each drive inserted in Step1 displays the solid green indication and remains in that state for 10 seconds.
Note: If one or more of the disk drives inserted does not display the solid green indication after 70 seconds, remove the drive(s) and check for damaged connectors on the disk drive and drive enclosure. If no damage is found, repeat Steps 1 and 2. After two attempts, replace drives that do not display the solid green indication.
3. When all of the inserted disk drives successfully display the solid green indication, repeat this procedure for the next set of one to four disk drives until all the disk drives have been inserted.

Protecting Fiber Optic Connections
This section describes the procedures and processes for protecting and cleaning fiber optic connectors. Fiber optic cabling is used to connect the storage system to the host or fabric.
Contamination of the fiber optic connectors on either a transceiver or a cable connector can impede the transmission of data. Therefore, protecting the connector tips against contamination or damage is imperative. The tips can be contaminated by touching them, by dust, or by debris. They can be damaged when dropped. To protect the connectors against contamination or damage, use the dust covers or dust caps provided by the manufacturer. These covers are removed during installation, and are installed whenever the transceiver or cables are disconnected. Cleaning the connectors should remove contamination.
The transceiver dust caps protect the transceivers from contamination. The transceivers protect the I/O modules from contamination.
Caution:
To avoid damage to the connectors, always install the dust covers or dust caps whenever a transceiver or a fiber cable is disconnected. Remove, but do not discard
, the dust covers or dust caps from transceiver or fiber cable connectors only when they are connected.
To minimize the risk of contamination or damage, implement the following guidelines:
■
Dust Covers
Remove and retain the dust covers and dust caps when installing an I/O module, a transceiver or a cable. Install the dust covers when disconnecting a transceiver or cable.
■
■
When to Clean
Any time you think a connector may be contaminated, or if a connector has not been protected by a dust cover for an extended period of time, clean the connector.
How to Clean a.
Wipe the connector with a lint-free tissue soaked with 100% isopropyl alcohol.
b.
Wipe the connector with a dry, lint-free tissue. c.
Dry the connector with moisture-free compressed air.

redundancy
1. Element Redundancy—The degree to which logical or physical elements are protected by having another element that can take over in case of failure. For example, each loop of a device-side loop pair normally works independently but can take over for the other in case of failure.
2. Data Redundancy—The level to which user data is protected. Redundancy is directly proportional to cost in terms of storage usage; the greater the level of data protection, the more storage space is required.
redundant power configuration
A capability of the Enterprise Storage System racks and enclosures to allow continuous system operation by preventing single points of power failure.
■
For a rack, two AC power sources and two power conditioning units distribute primary and redundant AC power to enclosure power supplies.
■
For a controller or disk drive enclosure, two power supplies ensure that the DC power is available even when there is a failure of one supply, one AC source, or one power conditioning unit. Implementing the redundant power configuration provides protection against the loss or corruption of data.

Vraid0
A virtualization technique that provides no data protection. Host data is broken down into chunks and distributed on the disks comprising the disk group from which the virtual disk was created. Reading and writing to a Vraid0 virtual disk is very fast and makes the fullest use of the available storage, but there is no data protection (redundancy) unless there is parity.
Vraid1
A virtualization technique that provides the highest level of data protection. All data blocks are mirrored or written twice on separate physical disks. For read requests, the block can be read from either disk, which can increase performance. Mirroring takes the most storage space because twice the storage capacity must be allocated for a given amount of data.
Vraid5
A virtualization technique that uses parity striping to provide moderate data protection. Parity is a data protection mechanism for a striped virtual disk. A striped virtual disk is one where the data to and from the host is broken down into chunks and distributed on the physical disks comprising the disk group in which the virtual disk was created. If the striped virtual disk has parity, another chunk (a parity chunk) is calculated from the set of data chunks and written to the physical disks. If one of the data chunks becomes corrupted, the data can be reconstructed from the parity chunk and the remaining data chunks.
World Wide Name

write back caching
A controller process that notifies the host that the write operation is complete when the data is written to the cache. This occurs before transferring the data to the disk. Write back caching improves response time since the write operation completes as soon as the data reaches the cache. As soon as possible after caching the data, the controller then writes the data to the disk drives.
