1 Overview of the HP XP12000 Disk Array This disk array is part of the HP StorageWorks XP series of high-performance RAID-capable disk arrays used to store large quantities of data in an efficient and secure manner. XP disk arrays support multiple operating systems, platforms, and RAID groups.
the appropriate maintenance activity, without interruption to applications or hosts. For more information, see “HP StorageWorks XP Continuous Track” on page 16.
HP XP12000 product contents The HP XP10000 disk array product includes hardware, software, services, and support. Some additional components are required and others are optional, as described in this section.

2 HP XP12000 hardware components 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. This chapter describes the physical components of the disk array. CAUTION: Only your HP support representative can remove or replace hardware.
Figure 1 Fully configured HP XP12000 Disk Array Disk control frame The DKC controls the disk array. It contains the control panel, connection hardware, power supplies, SVP, and control boards for the disk array. It also contains 9 to 128 disk drives. 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. Figure 2 shows the control panel location and layout.
Figure 2 Control panel Table 3 Control panel functions Item Label Indicator Description During normal operation, this LED should be on. 1 SUB-SYSTEM READY LED (Green) ON: Input/output operation on the channel interface is enabled. OFF: The system is not accepting data.
Item Label Indicator Description 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. 2 SUB-SYSTEM ALARM LED (Red) An unrecoverable failure has occurred. If the disk array is set up to report errors to STC, your HP support representative is notified automatically.
Item Label Indicator Description During normal operation, this LED should be on. 8 PS-ON LED (Green) ON: The PS ON/OFF switch is on. If the SUB-SYSTEM READY light (1) is also on, the disk array is ready to receive data. OFF: The PS ON/OFF switch is off and the disk array is not ready to receive data. Used to enable the PS ON/OFF switch (10). During normal operation, this switch should be in the “Disable” position (opposite the ENABLE position).
Item Label Indicator Description Determines how the disk array is powered on or off. During normal operation, this switch may be in either position, depending on your operating environment. 13 PS REMOTE/ LOCAL Switch REMOTE: Disk array is powered on/off by the instructions of the host PCI (mainframe only). LOCAL: Disk array is powered on/off by the PS ON/OFF switch (10). Do not change the switch position unless directed to do so by HP service personnel.
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.
Optional management server HP XP Remote Web Console allows browser-based management of a single disk array. The optional HP Command View XP Advanced Edition software may be installed on a Device Manager server to enable additional management capabilities, including the ability to manage multiple arrays. Other HP StorageWorks XP software may also be installed on this host; see “HP XP12000 Software” on page 16 for information about optional HP software products.
3 HP XP12000 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 for remote support, the SVP automatically reports SIMs to the HP Storage Technology Center (STC). For more information about SIMs, see “Service information messages” on page 35.
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. 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.
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.
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.
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 for remote support, 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.
Operating specifications This section provides some general specifications. For complete specifications, see the system site preparation guide, available on the HP XP Disk Array website: http://h18006.www1.hp.com/storage/xparrays.
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.

4 HP XP12000 Troubleshooting 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.
Item 5 36 Description If remote support is set up, HP XP Continuous Track reports the SIMs to STC through a dedicated dialup or Internet 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.
