Preface

1 Installation

You and your HP service representative each play a role in installation. Your HP service representative is responsible for installing the disk array and formatting the disk devices.

You are responsible for configuring the host server for the new devices with assistance from your HP service representative.

Features and requirements

Ask your HP service representative about the latest supported hardware and software.

The disk array has the following features:

Storage capacity. The storage capacity for each model is listed below:

XP128: From 8 to 128 drives for up to 36 TB, 48 FC ports

XP1024: From 8 to 1024 drives for up to 149 TB, 64 FC ports

XP10000: Up to 240 drives for up to 69.2 TB, 48 FC ports

Fibre Channel interface

The XP family of disk arrays supports these Fibre Channel elements:

• Connection speed of 1 Gbps and 2 Gbps

• Short-wave non-OFC (open fiber control) optical interface

• Multimode optical cables with SC or LC connectors

• Public or private arbitrated loop (FC-AL) or direct fabric attach

Even though the interface is Fibre Channel, this guide uses the term “SCSI disk” because disk array devices are defined to the host as SCSI disks.

Device emulation types

The XP family of disk arrays supports these device emulation types:

OPEN-3/8/9/E/L/V devices: OPEN-x logical units represent disk devices.

Except for OPEN-V, these devices are based on fixed sizes. OPEN-V is a user-defined size. Supported emulations include OPEN-3, OPEN-8, OPEN-9,

OPEN-E, OPEN-L, and OPEN-V devices.

x

* n

): Logical Unit Size Expansion (LUSE) devices combine •

LUSE devices (OPEN-

2 to 36 OPEN-x devices to create expanded LDEVs larger than standard

OPEN-3/8/9/E/L/V disk devices. For example, an OPEN-x LUSE volume created from ten OPEN-x volumes is designated as OPEN-x*10.

CVS devices (OPEN-x CVS): Volume Size Configuration (VSC) defines custom volumes (CVS) that are smaller than normal fixed-sized logical disk devices

(volumes). (OPEN-V is a CVS-based custom disk size that you determine. OPEN-L does not support CVS.)

LUSE (expanded) CVS devices (OPEN-x*n CVS): LUSE CVS combines CVS devices to create an expanded device. This is done by first creating CVS custom-sized devices and then using LUSE to combine from 2 to 36 CVS devices. For example, if three OPEN-9 CVS volumes are combined to create an expanded device, this device is designated as OPEN-9*3-CVS.

Failover

The XP family of disk arrays supports many standard software products that provide host, application, or I/O path failover and management.

10 Installation

SNMP configuration

The XP family of disk arrays supports standard Simple Network Management Protocol

(SNMP) for remotely managing the disk array. The SNMP agent on the service processor

(SVP) performs error-reporting operations requested by the SNMP manager. SNMP properties are usually set from the SVP but they can also be set remotely using Remote

Web Console XP, Command View XP, or Command View XP Advanced Edition. Refer to the applicable user’s guide for procedures.

RAID Manager command devices

RAID Manager manages Business Copy (BC) or Continuous Access (CA) operations from a host server. To use RAID Manager with BC or CA, you use Remote Web Console,

Command View, or Command View XP Advanced Edition to designate at least one LDEV as a command device. Refer to the applicable user’s guide for information about how to designate a command device.

Fabric zoning and LUN security

By using appropriate zoning and LUN security, you can connect various servers with various operating systems to the same switch and fabric:

• Storage port zones may overlap if more than one operating system needs to share an array port.

• Heterogeneous operating systems may share an XP array port if you use Secure

Manager and set the appropriate host group and mode. All others must connect to a dedicated XP array port.

• Use Secure Manager for LUN isolation when multiple hosts connect through a shared array port. Secure Manager provides LUN security by allowing you to restrict which LUNs each host can access.

• QLogic and Emulex HBAs must be in separate zones (a QLogic zone and an

Emulex zone) whether the HBAs are in the same or separate servers.

• If booting over the SAN, within a server, the booting HBAs must be from the same vendor. Additional data storage HBAs can be from a different vendor.

• If you plan to use clustering, install and configure the clustering software on the servers. Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node. Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster environment with three clusters, each containing two nodes. The nodes share access to the disk array.

Connect the disk array

The HP representative connects the cables between the array and the host or between the array and the SAN.

Defining the paths

Use Remote Web Console (shown), Command View, or Command View XP AE to define paths (LUNs) between hosts and volumes in the disk array.

This process is also called “LUN mapping.” In Remote Web Console and Command

View, LUN mapping includes:

• Configuring ports

• Enabling LUN security on the ports

• Creating host groups

• Assigning host bus adapter WWNs to host groups

• Mapping volumes to host groups (by assigning LUNs

22

In Command View XP AE, LUN mapping includes:

• Configuring ports

• Creating storage groups

• Mapping volumes and WWN/host access permissions to the storage groups

Installation

For details see the LUN Configuration and Security Manager User’s Guide or Command

View XP Advanced Edition Device Manager Web Client User’s Guide. Note the LUNS and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration.

NOTE:

A LUN assigned a number greater than FF is outside the accepted range of numbers for a Windows server (00 to FE) and will not be recognized by the server or be visible for use.

Windows 2003:

To see LUNs, you must create a LUN 0 when using the ScsiPort

Miniport Driver. This is not necessary if using the StarPort Miniport Driver.

Windows 2000:

A LUN 0 must be created to discover more than LUNs 0 to 7.

Verifying the host recognizes array devices

1.

Log into the host as an administrator.

2.

Right-click on the My Computer desktop icon, and click Manage.

3.

Configure disk devices

Disk arrays are configured using the same procedure for configuring any new disk on the host. This includes the following procedures:

• Writing signatures

• Creating and formatting disk partitions

• Verifying file system operations

Writing signatures

1.

Right-click on the My Computer desktop icon and click Manage.

2.

Click Disk Management. A message notifies you that disks have been added.

3.

Click OK to update the system configuration and start the Write Signature wizard, which allows you to write signatures to the disks.

4.

For each new disk, click OK to write a signature, or click No to prevent writing a signature.

5.

When you have performed this process for all new disks, the Disk Management main window opens and displays the added disks.

24 Installation

Creating and formatting disk partitions

Dynamic Disk is supported with no restrictions for a disk array connected to a Windows

2000/ 2003 system. Refer to Microsoft’s online help for details.

CAUTION:

Do not partition or create a file system on a device that will be used as a raw device

(for example, some database applications use raw devices.)

1.

In the Disk Management main window, select the unallocated area for the SCSI disk you want to partition.

2.

Click the Action menu, and click Create Partition to launch the New Partition

Wizard. Follow the Partition Wizard to create and format partitions and assign drive letters. Format partitions with the following settings and format options.

File System: NTFS (enables Windows to write to the disk).

Allocation unit size: “Default.” Do not change this entry.

Volume label: Enter a volume label, or leave this field blank for no label.

Format Options: Click Perform a Quick Format to decrease the time required to format the partition. Click Enable file and folder compression only if you want to enable compression.

3.

Verify the Disk Management main window displays the correct file system (NTFS) for the formatted partition. The word “Healthy” indicates that the partition has been created and formatted successfully.

4.

Repeat this procedure for each new disk device.

5.

Exit Disk Management, clicking Yes to save your changes.

Verifying file system operations

1.

Open My Computer and check that the new disks are present.

2.

Right-click on each disk to view Properties and verify the properties are correct

(label, type, capacity, and file system).

3.

Copy a file from an existing drive to each new drive to verify the new drives are working, and then delete the copies.

2 Troubleshooting

This section includes resolutions for various error conditions you may encounter.

If you are unable to resolve an error condition, ask your HP support representative for assistance. See

Calling the HP support center

.

Error conditions

Depending on your system configuration, you may be able to view error messages

(R-SIMS) as follows:

• In Remote Web Console (Status tab)

• In Command View Advanced Edition (“Alerts” panel).

• In Command View (Event History or Event Notification panels)

Error Condition

The logical devices are not recognized by the host.

Recommended Action

Verify that the READY indicator lights on the disk array are ON.

Verify that fiber cables are correctly installed and firmly connected.

Verify that the target IDs are properly configured. The LUNs for each TID must start at 0 and continue sequentially without skipping any numbers.

Verify that the TIDs/WWNs on each bus are unique. Do not install two devices with the same ID on the same bus.

Recheck the buses for new devices.

Verify that LUSE devices are not intermixed with normal LUNs on the same port.

Verify that the maximum number of LUSE devices per port has not been exceeded.

Verify that the disk array host mode is set correctly.

Disk Array XP operating system configuration guide: Windows 2000/2003

27

Error Condition

The host does not reboot properly after hard shutdown.

Physical volumes cannot be created.

Recommended Action

If you power off the host without executing the shutdown process, wait three minutes to allow the disk array’s internal timeout process to purge queued commands. If the host restarts while the disk array is processing queued commands, the host may not reboot successfully.

Verify that the disk array logical devices are correctly formatted.

Logical volumes cannot be created.

Verify that the volume capacity for

OPEN-x volumes is not greater than the maximum capacity allowed. See the Device

Emulations Appendix.

Verify that the capacity of the volume group is not less than the total capacity of the partitioned logical volume.

A file system is not mounted after rebooting. Verify that the host was restarted correctly.

Verify that the file system attributes are correct.

Reboot the host.

The disk array performs a self reboot because the disk array was busy or it logged a panic message.

The disk array responds “Not Ready” or the disk array has displayed “Not Ready” and timed out.

The host detects a parity error.

Contact HP.

The host hangs or devices are declared and the host hangs.

Check the HBA and make sure it was installed properly.Reboot the host.

Make sure there are no duplicate disk array

TIDs and that disk array TIDs do not conflict with any host TIDs.

Disk array supported emulations

Note 1:

The availability of an emulation depends on the disk array.

Note 2:

The devices are defined to the host as SCSI disk devices, even though the interface is

Fibre Channel.

Note 3:

The device capacity can sometimes be changed by the BIOS or host adapter board.

This may make actual capacity different from that listed in the table.

Note 4:

The number of blocks for a CVS volume is calculated as follows:

# of blocks = (# of cylinders) × (# of heads) × (# of sectors per track)

Example

For an OPEN-3 CVS volume with capacity = 37 MB:

# of blocks = (53 cylinders–see Note 5) × (15 heads) ×

(96 sectors per track) = 76320

Example

For an OPEN-V CVS volume with capacity = 49 MB:

# of blocks = (53 cylinders–see Note 5) × (15 heads) ×

(128 sectors per track) = 101760

Note 5:

The number of cylinders for a CVS volume is calculated as follows (↑…↑ means that the value should be rounded up to the next integer):

OPEN-3/8/9/E: The number of cylinders for a CVS volume = # of cylinders = ↑

(capacity (MB) specified by user) × 1024/720 ↑

Example

For an OPEN-3 CVS volume with capacity = 37 MB:

# of cylinders = ↑37 × 1024/720↑ = ↑52.62↑

(rounded up to next integer) = 53 cylinders

OPEN-V: The number of cylinders for a CVS volume = # of cylinders = ↑ (capacity

(MB) specified by user) × 16/15 ↑

Disk Array XP operating system configuration guide: Windows 2000/2003

35

Example

For an OPEN-V CVS volume with capacity = 49 MB:

# of cylinders = ↑49 × 16/15↑ = ↑52.26↑

(rounded up to next integer) = 53 cylinders

OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume = # of cylinders = ↑

(capacity (MB) specified by user) × 1024/720 ↑ × n

Example

For a CVS LUSE volume with capacity = 37 MB and n = 4:

# of cylinders = ↑37 × 1024/720↑ × 4 = ↑52.62↑× 4 = 53 × 4 = 212

OPEN-V: The number of cylinders for a CVS LUSE volume = # of cylinders = ↑ (capacity

(MB) specified by user) × 16/15 ↑ × n

Example

For an OPEN-V CVS LUSE volume with capacity = 49 MB and n = 4:

# of cylinders = ↑49 × 16/15↑ × 4 = ↑52.26↑× 4 = 53 × 4 = 212

Note 6:

The capacity of an OPEN-3/8/9/E CVS volume is specified in MB, not number of cylinders. The capacity of an OPEN-V CVS volume can be specified in MB or number of cylinders. You set the volume size using Remote Web Console, Command View, or Command View XP Advanced Edition.

Arbitrated loop.

Arbitrated loop physical address.

A group of 4 or 8 physical hard disk drives (HDDs) installed in an XP disk array and assigned a common RAID level. RAID1 array groups consist of 4 (2D+2D) or 8 HDDs (4D+4D). RAID5 array groups include a parity disk but also consist of 4 (3D+1P) or 8 HDDs (7D+1P). All RAID6 array groups are made up of

8 HDDs (6D+2P).

HP StorageWorks Business Copy XP. BC lets you maintain up to nine local copies of logical volumes on the disk array.

HP StorageWorks Continuous Access XP. CA lets you create and maintain duplicate copies of local logical volumes on a remote disk array.

HP StorageWorks Command View XP, a software product for managing XP arrays. Command View runs on a

Windows-based management workstation.

HP StorageWorks Command View XP Advanced Edition, installs on the user-provided Device Manager server and provides a browser-based platform from which you can manage the XP family of disk arrays—even globally distributed arrays.

command device

A volume on the disk array that accepts Continuous Access or Business Copy control operations which are then executed by the disk array.

CU

Control Unit. Contains LDEVs and is approximately equivalent to SCSI Target ID.

CVS

DKC

Custom volume size. CVS devices (OPEN-x CVS) are custom volumes configured using array management software to be smaller than normal fixed-size OPEN system volumes.

Synonymous with volume size customization (VSC).

The array cabinet that houses the channel adapters and service processor (SVP).

emulation modes

The logical devices (LDEVs) associated with each RAID group are assigned an emulation mode that makes them operate like

OPEN system disk drives. The emulation mode determines the size of an LDEV:

OPEN-3: 2.46 GB

OPEN-8: 7.38 GB

OPEN-9: 7.42 GB

OPEN-E: 13.56 GB

OPEN-L: 36 GB

OPEN-V: User-defined custom size

Disconnecting a failed unit or path and replacing it with an alternative unit or path in order to continue functioning.

Host bus adapter.

LDEV

LUN

LUSE

Each port can be configured for a particular host type. These modes are represented as two-digit hexadecimal numbers. For example, host mode 08 represents an HP-UX host.

Logical device. An LDEV is created when a RAID group is carved into pieces according to the selected host emulation mode (that is, OPEN-3, OPEN-8, OPEN-L). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is often used synonymously with the term volume.

Logical unit number. A LUN results from mapping a SCSI logical unit number, port ID, and LDEV ID to a RAID group.

The size of the LUN is determined by the emulation mode of the LDEV and the number of LDEVs associated with the LUN.

For example, a LUN associated with two OPEN-3 LDEVs has a size of 4,693 MB.

A LUN is normally associated with only a single LDEV. The

LUSE feature allows a LUN to be associated with 1 to 36

LDEVs. Essentially, LUSE makes it possible for applications to access a single large pool of storage. The LUSE feature is available when the HP StorageWorks LUN Configuration

Manager product is installed.

Open Fibre Control.

A general term describing any one of the supported OPEN emulation modes (for example, OPEN-L).

Operating system.

Physical address.

“Path” and “LUN” are synonymous. Paths are created by associating a port, a target, and a LUN ID with one or more

LDEVs.

A physical connection that allows data to pass between a host and the disk array. The number of ports on an XP disk array depends on the number of supported I/O slots and the number of ports available per I/O adapter. The XP family of disk arrays supports Fibre Channel (FC) ports as well as other port types. Ports are named by port group and port letter, such as CL1-A. CL1 is the group, and A is the port letter.
