XP128 Hardware 27

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

28 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 dat a stored on the disk array.

•(Optional) second service processor This is available for user s with ext reme high a vailabi lity re quirements .

This is not a required feature.

• Control panel The control panel is your view of the disk ar ray. 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 31.

• 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 t he disk array fra mes can

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

•(Optional) management station PC The management station PC is attached to your disk array by a local

area network (LAN) connecti on. The manageme nt stat ion PC runs HP Command View XP, which, combined with other optional applications, allows you to monitor and manage disk array operations.

The following figure illustrates how the management station PC and host connect to the XP128.

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 to connect for this purpose.

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

The hardware requirements for your management station PC, 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.

T o ens ure dat a secu ri ty, the HP Command V i ew XP soft ware doe s not ha ve 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 37.

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

1. Push the operator panel cover at the location where PUSH is marked, open the operator panel cov er, 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 inf ormation messages ( R-SIMs) to your management station PC running HP Command View XP, to the internal disk ar ray s ervic e p rocesso r, and also to the HP Service Cente r. For more information on SIMs, see Chapter 5, "Troubl es hoot in g" on page 89.

38 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 you to power down the disk array. These situations include:

• Emergency power-off

• Planned power-off

Emergency power-off

An emergency is a cr iti cal si tua tion s uch as a physical plant catast ro phe . 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 arr ay emer ge ncy pow er -o f f (EPO) s wit ch is located o n th e control panel.

Caution Use this switch only in case of an eme rgency. An HP ser vic e 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 cove r 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 Figure 4 on page 37.

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.

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 aff ects an HP St orageWorks Disk Array XP128, the power down of the disk array must be scheduled with a trained HP support representative.

XP128 Hardware 39

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 d isk array a t any time other than an emergency.

When planning for your pl ann ed powe r outag e, pl eas e con ta ct your HP CE to schedule a customer visit.

40 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 r esto r e po wer to t he disk array aft er an ou tage, 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 posit ion. Move the PWR ON/OFF switch to the PWR ON position (Fig ure 3 on page 31, items 11 & 12)

2. The following LED sequence will occur: The BS-ON LED (Figure 3 on page 31, item 9) will turn amber and

the PS ON LED (10, Figure 3 on page 31, item 10) will turn green. The CHANNEL LED (Figure 3 on page 31, item 7) will light green

for every adapter installed. The MESSAGE LED (Figure 3 on page 31, 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 31, item 1) will light green when the system is ready, which may take up to 10 minutes, dep ending on the number of disks installed in your disk array.

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

XP128 Hardware 41

Automatic power on restart

Caution As with all sophisticated electronic equi pment, 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 re start 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 31, 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 31, item 9) will turn amber and the PS ON LED (10, Figure 3 on page 31, item 10) will turn green.

The CHANNEL LED (Figure 3 on page 31, item 7) will light green for every adapter installed.

The MESSAGE LED (Figure 3 on page 31, 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 31, item 1) will light green when the system is ready, which may take up to 10 minutes, dep ending 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 cov er, 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 cir c uit. Therefore, do not use the switc hes on thes e units unless you need to power off of the unit as an emergency measure.

When pulled, the UNIT EMERGENCY PO WER OFF switch mecha nically 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.

66 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 cr iti cal si tua tion s uch as a physical plant catast ro phe . 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 eme rgency. An HP ser vic e 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 cove r by pushing on the point marked PUSH.

2. Pull the emer gency power-off s witch (Figure 11 on page 65) 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 67

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 arr ay must be scheduled with a traine d 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.

68 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 wil l ma in tai n i ts st at e f or a m in imum of 48 hour s. T his 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 69

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 posit ion. Move the PWR ON/OFF switch to the PWR ON position. (Figure 10 on

page 59, item 11/12)

2. The following LED power sequence will occur: The BS-ON (Figure 10 on page 59, item 9) will turn amber and the PS

ON LED (Figure 10 on page 59, item 10) will turn green. The CHANNEL LED (Figure 10 on page 59, item 7) will light green

for every adapter installed. The MESSAGE LED (Figure 10 on page 59, 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 10 on page 59, 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.

Automatic power on restart

Caution As with all sophisticated electronic equipment, unstable power conditions

during a res tart can indu ce pr oblems . HP r ecommends aut omatic 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 di sk array be conf igured for manual restart b y keepi ng 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 10 on page 59, item 1 1/ 12) . Wh en po wer i s res to red , your disk array will restart and the following LED power sequence will occur:

The BS-ON (Figure 10 on page 59, item 9) will turn amber and the PS ON LED (Figure 10 on page 59, item 10) will turn green.

The CHANNEL LED (Figure 10 on page 59, item 7) will light green for every adapter installed.

The MESSAGE LED (Figure 10 on page 59, 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 10 on page 59, 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.

Troubleshooting

This chapter explai ns the monito ring and repor ting capabil ities and the flow of troubleshooting us ed on th e HP S torag eWorks Disk Array family of disk arrays.

Troubleshooting 89

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.

90 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 occur s in the disk array , it is detected and reported to the syst em log, the SIM log, and the HP Storage Technology Center. Figure 12 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 s tored on your disk array’s SVP for use by HP

personnel and logged on the remote console PC as remote SIMs (R-SIMs). The Continuous Track remote maintenance software tool also reports SIMs to the HP Storage Technology Center. When a SIM is generated, the amber m essag e LED on your disk a rray co ntrol 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 T rack remote mai ntenance tool repor ts the SIMs to the HP Storage Technology Center through a dedi cated dia l up connect ion.

The HP Stora ge Technology Center then takes action t o c o r r e c t t h e failure.
