Preface

1 Overview

This disk array is part of the HP StorageWorks XP Disk Array family of products, which provide reliable and secure data storage and protection. These disk arrays also support multiple operating systems, platforms, and RAID groups. Advantages include:

• Continuous data availability

• Nondisruptive service and upgrades

• Connectivity

• Scalability

• Data integrity and high availability

Continuous data availability

The HP StorageWorks Disk Array XP family includes the first RAID disk arrays to provide truly continuous data availability. XP disk arrays are designed for nonstop operation and continuous access to all user data.

The following features ensure continuous data availability:

• No single point of component failure, which enables uninterrupted access to data

• Component and function redundancy, providing full fault tolerance for disk array microprocessors, control storage, cache, control and data buses, power supplies, and cooling fans

• Can sustain multiple component failures and still continue to provide full access to stored data

Note that although access to data is not compromised, the failure of a key component can cause a temporary reduction in disk array performance.

HP StorageWorks XP12000 Disk Array

11

Nondisruptive service and upgrades

Without disrupting normal disk array operations (if alternate pathing is used), an HP support representative can:

• Remove, service, repair, or replace hardware subassemblies

• Use the built-in service processor (SVP) to upgrade microcode

Alternate paths can be established using host failover software, alternate Fibre Channel paths, or both.

CAUTION:

The disk array has no user-serviceable components. The SVP does not include a keyboard or monitor and is not a customer-accessible component. Only an HP support representative should open the cabinets.

HP StorageWorks Continuous Track XP monitoring software detects internal hardware component problems and automatically reports them to the HP Storage Technology

Center (STC) before they are noticed by operators and users. An HP support representative can then verify the problem and perform the appropriate maintenance activity, with no interruption to applications or hosts. For more information on Continuous

Track XP, see

HP StorageWorks Continuous Track XP

.

Unit emergency power off switch

The UNIT EMERGENCY POWER OFF switch is located on the back of the DKC cabinet.

For more information about this switch, see

Emergency power off.

Service processor (SVP)

The Service Processor inside the controller performs these functions:

• Collects performance data on the system for diagnostic testing and analysis

• Provides your HP support representative with access to the system

• Hosts system management software

Your HP support representative uses the SVP to configure, maintain, and upgrade the system software and hardware. The SVP is not a customer-accessible component.

To protect your security, the SVP does not have access to any user data stored on array disks.

If you have extreme availability requirements, an optional second SVP is available.

Disk drives

The DKC must contain at least nine hard disk drives and can contain up to 128. For more information about disk drives, see the following section about disk drives in the DKUs.

HP StorageWorks Continuous Track XP

HP Continuous Track XP is a program in the system that detects and reports problems even before they are noticed by operators and users. HP Continuous Track XP “phones home” to the HP Storage Technology Center (STC), providing:

• Periodic “well” checkups

This checkup records the health of the disk array on a day-to-day basis. Every

24 hours, HP Continuous Track XP calls STC (your HP support representative sets the time of the call). When a successful connection is made, status information is transferred from the disk array to STC. If any configuration changes have been made, configuration information is also sent.

• Incidental “sick” calls

When an error occurs, a service information message (SIM) is generated, stored in the disk array for use by your HP support representative, and reported to STC. For more information, see

Service information messages

.

Note that the “phone home” capability can be turned off, if desired. HP Continuous Track

XP still monitors the disk array, but does not automatically notify HP if a problem occurs.

28

Hardware

Disk array frames

DKUs are optional cabinets that allow you to expand the disk array’s storage capacity.

DKUs contain physical disk drives. The disk array can include up to four DKUs. Four

DKUs fully populated with disk drives provide up to 332 TB of raw storage capacity.

Disk drives

Each DKU can contain up to 256 hard disk drives. The disk array automatically detects and corrects disk errors, and an HP support representative can replace any of the disk drives without disrupting user activity.

The disk array must contain at least one spare disk drive and can contain up to 40. Any of the spare disk drives can back up any other disk drive of equal rotational speed and equal or lesser capacity, in any DKU, even if the failed disk and the spare disk are in different array domains.

The XP12000 supports 73 GB, 146 GB, and 300 GB Fibre Channel disk drives. Fibre

Channel drives are intended as a high capacity, high performance storage option for high priority applications such as OLTP, Oracle, SAP, and Exchange.

RAID options

The disk array supports RAID1 (2D+2D or 4D+4D), RAID5 (3D+1P or 7D+1P), and

RAID6 (6D+2P) array groups. RAID levels may be intermixed.

HP StorageWorks XP12000 Disk Array

29

Backup batteries

In each frame (DKC and DKU), internal nickel-metal-hydride batteries provide backup power for the cache memory, shared memory, ACPs, CHIPs, and disk drives. If AC input power is lost, the backup batteries enable the disk array to continue normal operations for up to one minute. If power is not restored within one minute, the disk array executes either the De-Stage or Backup battery operation mode.

1

2

If power is restored during the de-staging process, the disk array continues with the data de-staging and power off processes.

If power is restored during the battery backup period, the disk array either automatically restarts or must be restarted manually, depending on the setting of the AUTO PS-ON ENABLE/DISABLE switch on the control panel.

HP representatives will help you determine the best battery mode for your configuration, and will configure the selected mode during installation.

30

Hardware

Disk array management

HP Remote Web Console (RWC) allows browser-based management of a single disk array. The optional HP Command View XP Advanced Edition software may be installed on an optional Device Manager server to enable additional management capabilities, including the ability to manage multiple arrays. Other HP StorageWorks XP Disk Array software may also be installed on this host; see

HP StorageWorks XP Disk Array family of software products

for information about optional HP software products.

To protect your security, Remote Web Console and HP Command View XP Advanced

Edition do not have access to user data stored on the disk array.

You may use an existing host (such as your storage administrator’s PC) as the Device

Manager server provided that it meets system requirements for the software you plan to deploy.

The CV XP AE Device Manager server connects to the disk array(s) using an Ethernet

LAN connection, as shown in the following figure.

General safety guidelines

Carefully read these safety guidelines and follow them when working with the disk array.

• Fully understand and follow all hazard warnings in this guide and on warning labels on the disk array. These hazard warnings help you to prevent or reduce the risk of death, personal injury, or product damage. Hazard warnings include alert headings consisting of an alert symbol and the word Caution or Warning.

CAUTION:

This indicates a hazardous situation which, if not avoided, will or can result in serious product damage or loss of data.

WARNING!

This indicates a potentially hazardous situation which, if not avoided, can result in death or serious injury.

• Replace any warning label that becomes dirty or starts peeling off.

• Keep in mind that the hazard warnings in this guide and on the disk array cannot cover every possible hazard because it is impossible to predict and evaluate all potentially hazardous circumstances. Be alert and use common sense. If you have any questions, contact your HP support representative.

• Follow the safety guidelines and procedures in all documentation for this and related products.

CAUTION:

Disk array maintenance must be done only by trained and qualified HP support representatives. Only an HP support representative can power off the disk array, except in an emergency.

CAUTION:

Do not perform any procedures not described in this guide. If you have any questions or concerns, contact your HP support representative.

WARNING!

Do not touch areas marked HAZARDOUS, even with the power off. These areas contain high-voltage power.

38 Operations

CAUTION:

If you detect any abnormal noise, smell, or smoke coming from the disk array, immediately power off the disk array by following the emergency power off procedure later in this chapter. For routine power off in non-emergency situations, contact your HP support representative.

CAUTION:

Do not power off the system unless it is an emergency situation and you follow the procedure for Emergency power off.

CAUTION:

Keep the front and rear doors closed at all times.

CAUTION:

Keep the tops and sides of the cabinets clear to allow air to flow properly.

CAUTION:

Use the supplied power cord. The power cord may not be used with other products.

HP StorageWorks XP12000 Disk Array

39

Powering down the disk array

Two situations may arise when you need to power down the system:

• Planned power off

• Emergency power off

Planned power off

Occasionally, you may need to plan a site power outage, such as during alterations to the data center, inspections, or work by the electric company. If a scheduled power outage will affect the disk array, contact your HP support representative to schedule a planned power off.

CAUTION:

Only a trained HP support representative can shut down and power off the disk array.

Do not attempt to power down the disk array other than during an emergency.

Emergency power off

In an emergency, it is critical to remove power to the disk array as quickly as possible.

CAUTION:

Performing the emergency power off procedure immediately shuts down the disk array, neglecting the array’s normal power off sequence. Jobs in process are aborted and their integrity after recovery is not guaranteed. Use this power off method only in an emergency. Only a qualified HP support representative can reset the switch and restore power to the disk array.

Emergency situations in which you should consider performing the emergency power off procedure are:

• A physical location catastrophe such as a flood, hurricane, tornado, or earthquake

• Any circumstance that presents the threat of injury or death to a person

• You detect any smoke, abnormal loud noise, or smell coming from the disk array

40 Operations

To power off the disk array in an emergency:

1.

Locate the UNIT EMERGENCY POWER OFF switch on the back side of the DKC. Its location is shown in the following figure.

2.

Pull the switch up and then out towards you.

The disk array shuts down immediately. The UNIT EMERGENCY POWER OFF switch mechanically locks itself in the off position to prevent anyone from restoring power in a potentially hazardous situation.

WARNING!

The UNIT EMERGENCY POWER OFF switch provides only partial power off capability.

AC input power remains present at the primary circuit.

3.

When the emergency situation is over, call the HP support center. Only a qualified

HP support representative can reset the switch and restore power to the disk array.

HP StorageWorks XP12000 Disk Array

41

Recovering from an unplanned power outage

Unplanned power outages occur when the primary building power is lost due to electrical blackouts, thunderstorm activity, or similar occurrences, and input AC power is not received by the disk array. The disk array will maintain its state and recover when power is restored.

The disk array cache is powered by backup batteries that will maintain the array state for up to 48 hours, depending on the selected battery operation mode. For more information, see “

Backup Batteries .”

Manual restart after power is restored

CAUTION:

After power is restored to your site and before restoring power to the disk array, HP recommends that you have an electrician verify the power to ensure that all phases are restored and input power to the disk is stable.

Contact your HP representative for help recovering from a power outage.

To restart the disk array manually:

1.

Move the PS ENABLE switch to the ENABLE position.

2.

Move the PS ON/OFF switch to the ON position.

The following LED power sequence occurs:

BS-ON turns amber.

PS-ON turns green.

SUB-SYSTEM MESSAGE may turn amber if the disk array is not configured to

“phone home,” signifying a SIM was generated because of the power outage.

SUB-SYSTEM READY turns green, indicating the system is ready.

CAUTION:

Powering on the disk array can take up to 10 minutes, depending on the number of disks installed in the disk array. Power on is complete only when the SUB-SYSTEM READY LED turns green.

Move the PS ENABLE switch to “DISABLE” (opposite ENABLE).

42 Operations

Automatic restart when power is restored

CAUTION:

As with all sophisticated electronic equipment, unstable power conditions during a restart can cause problems. HP recommends automatic power on restart only if the power to the disk array is subject to power conditioning equipment, such as a UPS, to ensure that the power restored to the disk array is stable. If your site does not have a

UPS, HP recommends that the disk array be configured for manual restart, meaning the POWER ENABLE switch on the control panel is in the DISABLE position. After a power outage, follow the manual restart procedure only after power has been restored and verified stable.

With automatic restart enabled, the disk array automatically restarts and returns to service when power is restored.

During the automatic restart, the following LED power sequence occurs:

• BS-ON turns amber.

• PS-ON turns green.

• SUB-SYSTEM MESSAGE may turn amber if the disk array is not configured to

“phone home,” signifying a SIM was generated because of the power outage.

• SUB-SYSTEM READY turns green, signifying the system is ready.

CAUTION:

Powering on the disk array can take up to 10 minutes and is complete only when the SUB-SYSTEM READY LED turns green.

To enable automatic restart:

Move the AUTO PS-ON ENABLE/DISABLE switch to the ENABLE position.

HP StorageWorks XP Tiered Storage Manager is a plug-in for the HP StorageWorks

Command View XP Advanced Edition Software. The plug-in migrates data to tiered storage systems according to quality of service requirements, matching the defined quality requirements of the data to the appropriate storage tier. It is a completely non-disruptive application that you can schedule or start immediately, once you have designed a migration plan. The software relieves you of data migration concerns, allowing you to define the migration criteria once and then let the software handle migration automatically. Management via the HP Command View XP Advanced Edition

Software GUI ensures user friendly operation of the migration setup and process.

Attributes include such data as volume type, capacity, emulation type, RAID level and disk type. Groups are created which place similar demands on the storage resources.

HP StorageWorks XP Disk/Cache Partition

HP StorageWorks XP Disk/Cache Partition software runs on the disk array and can help Enterprise customers subdivide a large disk array into smaller storage segments for accomplishing corporate storage related initiatives such as consolidation, tiered storage, chargeback, and application usage tracking. Each domain or partition is separately configured and managed. Each partition has its own assigned host ports, disk groups, and cache. This software can reduce storage costs by dividing the disk array into smaller segments suitable for departmental usage, while retaining superb performance and high availability.

HP StorageWorks XP Data Shredder

HP StorageWorks XP Data Shredder securely erases selected data volumes with up to eight overwrite passes to minimize the chance that unauthorized users could recreate the data.

Replication software

HP StorageWorks Business Copy XP and Snapshot XP

HP Business Copy allows you to make up to nine ongoing copies of data for nonproduction activities such as backup, batching, and system testing. HP Business Copy and the disk array now support enhanced HP Snapshot features. HP Snapshot is optional software that creates multiple, point-in-time, online, local copies without impacting primary production operation. The enhanced HP Snapshot features include support for snapshots on external storage, up to 128 snapshot pools per system, and restoring data from any previous generation. HP Snapshot may require additional shared memory.

HP StorageWorks Continuous Access Synchronous

HP Continuous Access Synchronous software allows you to make ongoing synchronous copies of array data to a remote array located many miles away from the source array.

HP StorageWorks Continuous Access Asynchronous

HP Continuous Access Asynchronous is similar to HP Continuous Access Synchronous, but operates in asynchronous mode. Transactions to be written to the secondary array are kept in cache memory on the local array in a “side-file.” This potentially increases performance in remote copying. Copy operations are sequence-stamped to ensure they are executed and sorted correctly at the remote disk array.

HP StorageWorks Continuous Access Journal

HP StorageWorks Continuous Access Journal is an asynchronous mirroring program similar to HP Continuous Access Asynchronous except that transactions to be written to the secondary array are kept in a disk-based journal file. This provides better performance for secondary systems that are not highly available or that may be subject to bandwidth contention from other applications. HP Continuous Access Journal supports cascading configurations, multiple target sites, external storage connections, up to

256 journal groups, online journal volume expansion, and several Open system and mainframe emulation modes.

HP StorageWorks RAID Manager XP

HP StorageWorks RAID Manager XP (RM) enables you to perform operations with HP

Service information messages

The system generates service information messages (SIMs) to identify normal operations, service requirements, and failures. SIMs are generated by the SVP and the system microprocessors. Your HP support representative uses the SIMs to monitor and troubleshoot the system. You can view SIMs using the system’s management software.

HP StorageWorks XP12000 Disk Array

Failure detection and reporting process

If a failure occurs in the system, the failure is detected and reported to the system log, the

SIM log, and the HP STC, as shown in the following figure and table.

Description

A failure is detected in the system.

The failure is reported to the system.

The system stores the failure information in the system log.

The generated SIMs are stored on the system for use by HP support representatives, and logged on the Device Manager server as remote SIMs

(R-SIMs).If the system is not set up to “phone home,” when a SIM is generated, the amber message LED on the system control panel turns on. Call HP to determine the reason for the message.

If the system is set up to “phone home,” HP Continuous Track XP reports the SIMs to STC through a dedicated dialup connection.SIMs are classified according to severity: service, moderate, serious, or acute. Service and moderate levels do not require immediate attention and are addressed during routine maintenance.

These failures are often corrected before the failure becomes apparent. Serious and acute levels are reported immediately to STC to ensure that the problem is addressed as soon as possible.
