Overview

The Disk Array XP128 and Disk Array XP1024 are part of the HP StorageWorks Disk Array family of products. These disk arrays provide reliable and secure data storage and protection, featuring redundant circuitry and RAID storage options for data security. These disk arrays also support multiple operating systems, platforms, and RAID groups. The advantages include:

• Continuous data availability

• Nondisruptive service and upgrades

• Connectivity

• Scalability

• Data integrity

Overview 11

Continuous data availability

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

The disk array has component and function redundancy, providing full fault tolerance for disk array microprocessors, control storage, control and data buses, power supplies, and cooling fans. The disk array can sustain multiple component failures and still continue to provide full access to your stored data.

While access to your data is never compromised, the failure of a key component can cause a temporary reduction in disk array performance.

12 HP StorageWorks Disk Arrays XP128/XP1024 Owner’s Guide

Nondisruptive service and upgrades

Monitoring software detects internal hardware component problems and notifies the HP Storage Technology Center automatically. At the support center, the problem is verified and the appropriate maintenance activity is executed by an HP service representative. The are no user serviceable components. Only an HP service representative should open the cabinets.

All hardware subassemblies can be removed, serviced, repaired, or replaced non-disruptively during disk array operation. All microcode upgrades can be performed during normal disk array operations (provided array connectivity infrastructure requirements are satisfied), using your disk array’s built-in service processor (SVP). Alternate paths can be set by host failover software and/or alternate Fibre Channel paths.

• Do not perform any procedures not described in this document. If you have any questions or concerns, please contact your HP service representative.

Warning

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

Keep in mind that the hazard warnings in this manual or on the machine cannot cover every possible case, as it is impossible to predict and evaluate all circumstances before hand.

Follow the procedures in this guide carefully and always be alert for any unusual equipment indications or behavior. If you have any questions, contact your HP service representative.

XP128 hardware 25

Physical components

The HP StorageWorks Disk Array XP128 is a high-performance disk array system. It is used to store large quantities of data in an efficient and secure manner.

Figure 1. HP StorageWorks Disk Array XP128

Your disk array has the following major hardware components:

• Disk array cabinet The single disk array frame cabinet contains the control panel,

connection hardware, the service processor, control boards and hard disk drives.

• One service processor (SVP) The service processor (SVP) is a built-in PC inside the disk array

cabinet. The SVP gives your HP service representative a method of accessing the software system on the disk array.

Your HP service representative uses the SVP to configure, maintain, and upgrade your disk array software and hardware. The service

26 HP StorageWorks Disk Arrays XP128/XP1024 Owner’s Guide

processor also collects performance data about the disk array for diagnostic testing and analysis.

To ensure data security, the SVP does not have access to any user data stored on the disk array.

•(Optional) second service processor

This is available for users with extreme high availability requirements. This is not a required feature.

• Control panel The control panel is your view of the disk array. Once the disk array is

powered on and running normally, there are no user operations required at the control panel, except in the case of a power failure recovery. The control panel is discussed in further detail on

page 29.

• Hard disk drives The disk array uses 3.5-inch disk drives, and different disk capacities

are available. Ask your HP service representative about currently available disk drives or visit the XP128 web site at

http://www.hp.com. Any of the disk drives in the disk array frames can

be replaced without disrupting user activity. The disk array automatically detects and corrects disk errors.

•(Optional) Device Manager server The Device Manager server is attached to your disk array by a local

area network (LAN) connection. The Device Manager server runs HP Command View XP and/or Command View XP Advanced Edition which, combined with other optional applications, allows you to monitor and manage disk array operations.

The following figure illustrates how the Device Manager server and host connect to the XP128.

XP128 hardware 27

Device Manager server

XP128 Disk Array

Host

Figure 2. The XP128 connections

1. The management station connects to the XP128 by means of a public LAN connection. The XP128 has an Ethernet connection for this purpose.

2. The host server uses a Fibre Channel, FICON, iSCSI, or ESCON connection.

The hardware requirements for your Device Manager server, such as the required processor speed, storage capacity, and memory, will vary depending on the optional software that you use and the number of disk array frames you have connected to the system.

To ensure data security, neither edition of HP Command View software (CVXP or CVXP AE) has access to any user data stored on the disk array.

There is no single point of failure in the disk array. It is designed with redundant logic assemblies, disk drives and power supplies, all of which can be removed or replaced without interrupting access to your data.

Caution Only your HP service representative can remove or replace hardware.

Emergency power-off

A switch is provided on the control panel for an emergency powering off. See Figure 4 on page 35.

If you detect an abnormal sound, smell, or smoke, power off the disk subsystem by operating the UNIT EMERGENCY POWER OFF switch following the procedure below. The procedure for operating the switch is as follows:

1. Push the operator panel cover at the location where PUSH is marked, open the operator panel cover, then operate the EMERGENCY POWER OFF switch.

2. In using a UNIT EMERGENCY POWER OFF switch, first pull it up and then pull it toward you as illustrated in the figure below.

Caution Pulling the UNIT EMERGENCY POWER OFF switch on the disk array

cabinet instantly shuts down the array, neglecting the system’s power-off sequence. Jobs in process are aborted and their integrity after recovery is not guaranteed. Therefore, this method should be used only in an emergency and not in normal operation.

Caution The UNIT EMERGENCY POWER OFF switch on the disk array cabinet

only partially removes power from the array. AC input power remains present at the primary circuit. Therefore, do not use the Emergency Power-Off switch unless you need to power off of the unit as an emergency measure.

When pulled, a UNIT EMERGENCY POWER OFF switch locks itself to prevent further powering on and requires a trained and qualified HP field engineer for recovery. Any time the unit Emergency/Only OFF switch is pulled, place a service call to Hewlett-Packard to have the switch reset and have the disk array restored to service.

Normal operations

The disk array does not require user intervention. The disk array automatically reports any remote system information messages (R-SIMs) to your Device Manager server running HP Command View XP or Command View XP Advanced Edition, to the internal disk array service processor, and also to the HP Service Center. For more information on SIMs, see Chapter 5, "Troubleshooting" on page 87.

Powering down the disk array

Situations may arise in the operation of the disk array that require you to power down the disk array. These situations include:

• Emergency power-off

• Planned power-off

Emergency power-off

An emergency is a critical situation such as a physical plant catastrophe. In an emergency, the critical need is to quickly remove power from the disk array. A quick restart is not necessary.

In an emergency, the operator should trip the Emergency Power-Off (EPO) switch. The disk array emergency power-off (EPO) switch is located on the control panel.

Caution Use this switch only in case of an emergency. An HP service representative

is required to reset the EPO and to power-on the disk array.

To power off the disk array in an emergency:

1. Open the control panel cover by pushing on the point marked PUSH.

2. Pull the emergency power-off switch up and then out towards you as illustrated on the switch. See

3. Call the HP support center. The EPO switch must be reset by an HP service representative before the disk array can be powered on again.

Figure 4 on page 35.

Planned power-off

There may be times when a site power outage is planned. These situations would include alterations to the data center, inspections, or work by the electric company. If a scheduled power outage affects an HP StorageWorks Disk Array XP128, the power down of the disk array must be scheduled with a trained HP support representative.

XP128 hardware 37

Caution Only a trained HP representative can shut down and power-off a disk

array. Shutting down and powering off a disk array is not a customer activity. A user should not attempt to power down the disk array at any time other than an emergency.

When planning for your planned power outage, please contact your HP CE to schedule a customer visit.

38 HP StorageWorks Disk Arrays XP128/XP1024 Owner’s Guide

Recovering from a power outage to the disk array

If AC input power is lost, the disk array maintains its state and recovers when power is restored. The array cache is backed up by batteries that will maintain its state for a minimum of 48 hours. This length of time will provide coverage for most outages. In cases where the outage will extend beyond 48 hours, the batteries can be replaced by a HP to extend the time, if necessary. To extend the backup time beyond 48 hours, you must notify HP support in time to receive service.

Manual restart of the disk array after power is restored

Caution Before you restore power to the disk array after an outage, HP recommends

you have an electrician check the power to ensure it is stable and clean.

You may opt to call a trained HP representative or you may restore power to the disk array yourself:

1. Move the ENABLE/DISABLE switch to the ENABLE position. Move the PWR ON/OFF switch to the PWR ON position ( items 11 & 12)

Figure 3 on page 29,

2. The following LED sequence will occur: The BS-ON LED (Figure 3 on page 29, item 9) will turn amber and

the PS ON LED (10, Figure 3 on page 29, item 10) will turn green. The CHANNEL LED (Figure 3 on page 29, item 7) will light green

for every adapter installed. The MESSAGE LED (Figure 3 on page 29, item 3) may turn amber if

your disk array is not configured for automatic maintenance notification, signifying a SIM was generated (because the disk array went down unexpectedly).

Finally, the Ready LED (Figure 3 on page 29, item 1) will light green when the system is ready, which may take up to 10 minutes, depending on the number of disks installed in your disk array.

3. Move the ENABLE/DISABLE switch to the DISABLE position.

XP128 hardware 39

Automatic power on restart

Caution As with all sophisticated electronic equipment, unstable power during a

restart can induce problems. Hewlett-Packard recommends automatic power on restart only when the power to the disk array is conditioned to ensure stability (for example, using a UPS). If your site does not have a UPS, HP recommends configuring the disk array for manual restart by keeping the ENABLE/DISABLE switch in the DISABLE position and using the manual restart procedure when power has been restored and verified.

Your disk array will automatically restart and return to service when power is restored. To enable this feature, place the ENABLE/DISABLE switch in the ENABLE position and the PWR ON/OFF switch in the PWR ON position (Figure 3 on page 29, items 11 & 12). When power is restored, your disk array will restart and the following LED sequence will occur:

The BS-ON LED (Figure 3 on page 29, item 9) will turn amber and the PS ON LED (10, Figure 3 on page 29, item 10) will turn green.

The CHANNEL LED (Figure 3 on page 29, item 7) will light green for every adapter installed.

The MESSAGE LED (Figure 3 on page 29, item 3) may turn amber if your disk array is not configured for automatic maintenance notification, signifying a SIM was generated (because the disk array went down unexpectedly).

Finally, the Ready LED (Figure 3 on page 29, item 1) will light green when the system is ready, which may take up to 10 minutes, depending on the number of disks installed in your disk array.

Emergency power-off

A switch is provided on the operator panel on the front side of the disk control frame (DKC) for turning power off in an emergency.

If you encounter any abnormality such as an abnormal sound, smell, or smoke, power off the disk subsystem by operating the UNIT EMERGENCY POWER OFF switch following the procedure below. The procedure for operating the switch is as follows:

1. Push the operator panel cover at the location where PUSH is marked, open the operator panel cover, then operate the EMERGENCY POWER OFF switch.

2. In using a UNIT EMERGENCY POWER OFF switch, first pull it up and then pull it toward you as illustrated in the figure below.

Caution Pulling a UNIT EMERGENCY POWER OFF switch on the disk controller

instantly shuts down, neglecting the system’s power-off sequence. Jobs in process are aborted and their integrity after recovery is not guaranteed. Therefore, this method should be used only in an emergency and not in usual maintenance.

Caution The UNIT EMERGENCY POWER OFF switch on the disk controller only

provides partial power-off capability. AC input power remains present at the primary circuit. Therefore, do not use the switches on these units unless you need to power off of the unit as an emergency measure.

When pulled, the UNIT EMERGENCY POWER OFF switch mechanically locks itself in the off position to prevent restoring power in a potentially hazardous situation. A qualified HP service representative is required on site to restore power. Any time the unit Emergency/Only OFF switch is pulled, place a service call to Hewlett-Packard to have the switch reset and have the disk array restored to service.

The disk array does not require intervention from the user. The disk array reports any remote system information messages (R-SIMs) to your Device Manager server running HP Command View XP or Command View XP Advanced Edition. The internal disk array service processor also sends the report to the HP Service Center automatically. For more information on SIMs, see Chapter 5, "Troubleshooting" on page 87

64 HP StorageWorks Disk Arrays XP128/XP1024 Owner’s Guide

Powering down the disk array

Situations may arise in the operation of the disk array that require the user to power down the disk array. These situations include:

• Emergency power-off

• Planned power-off

Emergency power-off

An emergency is a critical situation such as a physical plant catastrophe. In an emergency, the critical need is to quickly remove power from the disk array. A quick restart is not necessary.

In an emergency, you should trip the Emergency Power-Off (EPO) switch, which is located on the control panel.

Caution Use this switch only in case of an emergency. An HP service representative

is required to reset the EPO and to power-on the disk array.

To power off the disk array in an emergency:

1. Open the control panel cover by pushing on the point marked PUSH.

2. Pull the emergency power-off switch (Figure 12 on page 63) up and then out towards you as illustrated on the switch.

3. Call the HP support center. The EPO switch must be reset by an HP service representative before the disk array can be powered on again.

XP1024 hardware 65

Planned power-off

Caution Only a trained HP representative may shut-down and power-off a disk

There may be times when a site power outage is planned, such as to make alterations to the data center, do inspections, or to allow work by the electric company. If a scheduled power outage affects an HP Disk Array XP1024, the power down of the disk array must be scheduled with a trained HP support representative.

array. Shutting down and powering off a disk array should not be done by customers except in an emergency.

When planning for your planned power outage, please contact your HP customer engineer to schedule a customer visit.

66 HP StorageWorks Disk Arrays XP128/XP1024 Owner’s Guide

Recovering from a power outage to the disk array

If a power outage to the array occurs, the disk array will maintain its state and recover when power is restored. The array cache is backed up by batteries that will maintain its state for a minimum of 48 hours. This length of time will provide coverage for most outages. In cases where the outage will extend beyond 48 hours, the batteries can be replaced by an HP CE which will extend the time, if necessary. You must notify HP support if your power outage is expected to extend beyond the backup time.

XP1024 hardware 67

Manual restart of the disk array after power is restored

Caution Before restoring power to the disk array, HP recommends that an

electrician check the input power to ensure it is stable and clean.

You may call a trained HP representative or you may use the following procedure yourself to recover the disk array from a power failure:

1. Move the ENABLE/DISABLE switch to the ENABLE position. Move the PWR ON/OFF switch to the PWR ON position. (

page 57, item 11/12)

2. The following LED power sequence will occur: The BS-ON (Figure 11 on page 57, item 9) will turn amber and the PS

ON LED (Figure 11 on page 57, item 10) will turn green. The CHANNEL LED (Figure 11 on page 57, item 7) will light green

for every adapter installed. The MESSAGE LED (Figure 11 on page 57, item 3) may turn amber,

if your disk array is not configured for automatic maintenance notification, signifying a SIM was generated (because the disk array went down unexpectedly).

Figure 11 on

Finally, the READY LED (Figure 11 on page 57, item 1) will light green signifying the system is ready. Powering on the disk array may take up to 10 minutes, depending on the number of disks installed in the disk array. Power-on is complete only when the READY LED turns green.

3. Move the ENABLE/DISABLE switch to the DISABLE position.

68 HP StorageWorks Disk Arrays XP128/XP1024 Owner’s Guide

Automatic power on restart

Caution As with all sophisticated electronic equipment, unstable power conditions

during a restart can induce problems. HP recommends automatic power on restart only when power to the disk array is conditioned to ensure it is stable, such as by using a UPS. If your site does not have a UPS, HP recommends the disk array be configured for manual restart by keeping the ENABLE/DISABLE switch in the DISABLE position and using the manual restart procedure when power has been restored and verified.

The disk array will automatically restart and return to service when power is restored. To enable this feature, place the ENABLE/DISABLE switch in the ENABLE position and the PWR ON/OFF switch in the PWR ON position. (Figure 11 on page 57, item 11/12). When power is restored, your disk array will restart and the following LED power sequence will occur:

The BS-ON (Figure 11 on page 57, item 9) will turn amber and the PS ON LED (Figure 11 on page 57, item 10) will turn green.

The CHANNEL LED (Figure 11 on page 57, item 7) will light green for every adapter installed.

The MESSAGE LED (Figure 11 on page 57, item 3) may turn amber, if your disk array is not configured for automatic maintenance notification, signifying a SIM was generated (because the disk array went down unexpectedly).

Finally, the READY LED (Figure 11 on page 57, item 1) will light green when the system is ready, which may take up to 10 minutes, depending on the number of disks installed in the disk array.

You can configure up to eight multiple paths per LUN that will provide automatic and transparent failover in the event of path failure. You can also enable dynamic, multi-path load balancing to prevent overloaded I/O operations.

HP StorageWorks Secure Path

HP StorageWorks Secure Path is a family of high availability multi-pathing software products providing continuous data access from the disk array to host servers running Windows Server 2003, Windows 2000, Windows NT, Linux, Sun Solaris, Novell NetWare, IBM AIX, and HP-UX.

Redundant hardware, advanced RAID technology and Secure Path’s automated failover capability enhance fault tolerance and availability. Secure Path effectively eliminates controllers, disk drives, interconnect hardware and host bus adapters as single points of failure. Secure Path:

• Ensures increased business efficiency by maintaining high availability of business critical data and by simplifying the task of path management.

• Monitors path status, and in the case of a path failure, automatically re-routes data to an alternate path.

• Allows easy path management from a single application with graphical displays and task automation.

Optional software products 81

Performance management

HP StorageWorks Cache LUN XP

Cache LUN XP enables you to reserve disk array cache memory for storing high-use data, greatly increasing access speed to that data.

HP StorageWorks Auto LUN XP

Auto LUN XP provides monitoring and disk usage analysis for your disk array based on user thresholds. Auto LUN develops a plan to migrate impacted data volumes to lower usage LUNs, using the data acquired during monitoring. You can perform the migration manually or automatically.

HP StorageWorks Performance Advisor XP

HP StorageWorks Performance Advisor XP is an Internet application used to monitor real-time performance of the HP StorageWorks XP family of disk array products. Using a simple, browser-based interface, you can quickly customize performance data collection and set performance alarms. Performance Advisor provides real-time and historical data on:

• LDEV I/Os

• front-end and back-end port utilization

• internal bus utilization

• cache usage

You can easily integrate with VantagePoint’s DSI log and user PerfView to view your performance metrics.

82 HP StorageWorks Disk Arrays XP128/XP1024 Owner’s Guide

HP StorageWorks Application Policy Manager XP

HP StorageWorks Application Policy Manager XP is a performance allocation and management tool for XP disk arrays. It lets you allocate storage performance resources to hosts by means of policies you define.

It ensures that critical business processes have all the XP disk array performance they need to meet business objectives. You can ensure that processes such as backups and data warehouse loads get the array bandwidth necessary to meet deadlines. Application Policy Manager enables sophisticated service provider solutions based on distinct levels of service.

Application Policy Manager has a rich feature set for flexible policy definition, scheduling, monitoring, and analysis.

Optional software products 83

Network management products

HP OpenView SPI for XP Disk Arrays

HP OpenView SPI for XP Disk Arrays establishes an agent that monitors XP disk arrays, provides a correlation of events on the disk arrays, and then forwards those events to the OpenView Operations management console.

Troubleshooting

This chapter explains the monitoring and reporting capabilities and the flow of troubleshooting used on the HP StorageWorks Disk Array family of disk arrays.

Troubleshooting 87

Monitoring and reporting

The disk array generates service information messages (SIMs) to identify normal operations, service requirements, and failures. SIMs can be generated on the disk array by the CHIP (Client Host Interface Processor) and ACP (Array Control Processor) microprocessors and by the internal service processor (SVP). Your HP service representative will use the SIMs to monitor and troubleshoot your disk array.

88 HP StorageWorks Disk Arrays XP128/XP1024 Owner’s Guide

Troubleshooting flow diagram

When the system encounters trouble, it will report the trouble to the HP Storage Technology Center.

If a failure occurs in the disk array, it is detected and reported to the system log, the SIM log, and the HP Storage Technology Center. Figure 13 is a flow diagram that explains the progress of error detection and reporting.

1. A failure is detected in your disk array.

2. The failure is reported to the system.

3. The system stores the failure information in the system log. The generated SIMs are stored on your disk array’s SVP for use by HP

personnel. The Continuous Track remote maintenance software tool also reports SIMs to the HP Storage Technology Center. When a SIM is generated, the amber message LED on your disk array control panel turns on if the disk array is not configured to automatically phone the HP Storage Technology Center. In this case, call HP to determine the reason for the message.

SIMs are classified according to severity: service, moderate, serious, or acute. Service-level and moderate-level SIMs do not require immediate attention and are addressed during routine maintenance. These failures are often corrected before the failure actually occurs.

Serious-level and acute-level SIMs are reported to the HP Storage Technology Center immediately to ensure that the problem is addressed as soon as possible. Your HP service representative will configure your modem during installation.

4. The Continuous Track remote maintenance tool reports the SIMs to the HP Storage Technology Center through a dedicated dial up connection.

The HP Storage Technology Center then takes action to correct the failure.
