Overview
2 Hardware The HP StorageWorks XP series of disk arrays are high-performance RAID-capable disk array systems used to store large quantities of data in an efficient and secure manner. There are no single points of failure in the disk arrays. They include redundant logic assemblies, controllers, disk drives, and power supplies, all of which can be removed or replaced without interrupting access to data. CAUTION: Only your HP support representative can remove or replace hardware.
Physical components The disk array includes the following major hardware components: • One disk control frame (DKC) • Zero to four disk array frames (DKUs) • One service processor (SVP) To monitor and manage the array, a Device Manager server is also required. The following figure shows the disk array with the maximum of four DKUs. The DKC alone constitutes the minimum configuration. Disk control frame The DKC controls the disk array.
Control panel Once the disk array is powered on and running normally, no user operations are required at the control panel, except when instructed by your HP support representative. The following figure shows the control panel location and layout. The accompanying table explains the control panel functions.
Item Label Indicator Description 1 SUB-SYSTEM READY LED (Green) During normal operation, this LED should be on. ON: Input/output operation on the channel interface is enabled. OFF: The system is not accepting data. 2 SUB-SYSTEM ALARM LED (Red) During normal operation, this LED should be off. ON: One or more of the following: The DC is under the voltage of the DKC part. The DC is over current. The temperature is abnormally high. An unrecoverable failure has occurred.
Item Label Indicator Description 5 REMOTE MAINTENANCE PROCESSING LED (Amber) During normal operation, this LED may be on if remote maintenance is allowed (the REMOTE MAINTENANCE ENABLE/DISABLE switch is in the ENABLE position). ON: Remote maintenance is in progress. An HP support representative is probably working on the system, but the system is online and accepting data. 6 REMOTE MAINTENANCE ENABLE/DISABLE Switch Used to permit remote service maintenance.
Item Label Indicator Description 10 PS ON/OFF Switch Used to power on/off the disk array. During normal operation, this switch should be in the ON position. The switch functions only if: The PS ENABLE switch (9) is in the ENABLE position. AND The PS REMOTE/LOCAL switch (13) is in the LOCAL position. Do not change the switch position unless directed to do so by HP service personnel. 11 EMERGENCY LED (Red) During normal operation, this LED should be on.
Item Label Indicator Description 12 AUTO PS-ON ENABLE/ DISABLE Switch Used to enable the automatic power on restart feature, which specifies how the disk array is powered on when the AC power is turned on or restored after a power outage. ENABLE: When the AC power is turned on, the disk array is powered on automatically.As with all sophisticated electronic equipment, unstable power conditions during a restart can cause problems.
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.
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.
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.
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.
Operating specifications This section provides some general specifications. For complete specifications, see the system site preparation guide, available on the HP XP Disk Array web site: http://h18006.www1.hp.com/storage/xparrays.html.
Humidity Protect the disk array from excessive humidity. You should not observe condensation in or around the product under any conditions. There is no procedure for recovery from moisture condensation.
AC line voltage requirements This section lists the AC power recommendations for each power cord. Each DKC or DKU has two or four power cords. In case of a failure of the power source for one cord, the power requirements, and therefore the current requirement for the remaining power cord, will double. For details on electrical specifications, cabling, and connectors, see the HP StorageWorks XP12000 Disk Array site preparation guide.
30-amp, 50 or 60 Hz, three-phase DKC Parameter 200 VAC 208 VAC 60 Hz only 220 VAC 230 VAC 240 VAC 380 VAC 400 VAC 415 VAC Rated line current per power cord (amps RMS) 13 12.5 11.9 11.3 10.9 6.9 6.5 6.

Units with only two power cords require only two circuit breakers.
3 Operations During normal operations, the disk array does not require your intervention and you should not attempt to open the disk array cabinets. The disk array reports any service information messages (SIMs) to the SVP and the Device Manager server. If the array is set up to “phone home,” the SVP automatically reports SIMs to the HP Storage Technology Center (STC). For more information about SIMs, see Service information messages.
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: 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.
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.
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.
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.
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.
