1 Overview of the HP XP24000/XP20000 Disk Array This disk array is part of the HP StorageWorks XP series of high-performance RAID-capable disk array systems used to store large quantities of data in an efficient and secure manner. XP disk arrays support multiple operating systems, platforms, and RAID groups.
NOTE: Although access to data is not compromised, the failure of a key component can cause a temporary reduction in disk array performance. 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...
Figure 1 Disk array simplified SAN connection Scalability The disk arrays are scalable to accommodate your current and future storage capacity needs. XP24000 basic configuration The XP24000 configuration consists of a disk control frame (primary rack) that can have 128HDDs and zero to 4 disk array frames (DKU) that can each have 256 HDDs for a total of 1152 hard drives.
One 60–disk chassis Adding storage You can add more disk chassis in this order: R0, R1, R2, and R3. Each disk chassis contains 60 hard disk drives. Your HP support representative can add disk chassis and disk drives online with no interruptions to applications or hosts.
Web-based array management The XP disk arrays come with HP StorageWorks XP Remote Web Console, a Java-based interface that runs on the SVP and enables you to manage one disk array. For managing multiple arrays, the optional HP StorageWorks XP Command View Advanced Edition software runs on a Windows-based server and can be accessed using remote web-based clients.

2 Hardware description of the HP XP24000/XP20000 Disk Array 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, power supplies, and dual-ported RAID disk drives, all of which can be removed or replaced without interrupting access to data.
Figure 2 XP24000 system architecture XP20000 system architecture Figure 3 shows, the basic XP20000 disk array consists of three main sections: the power supply, a DKC, and a DKU. The power supply section consists of the AC-DC power supplies and battery boxes. The DKC consists of the channel adapters (CHAs), disk adapters (DKAs), cache memory adapters (CMAs), and shared memory adapters (SMAs).
Figure 3 XP20000 system architecture Physical assemblies The XP24000 disk array includes the following major hardware assemblies (see Figure One disk control frame (DKC) Zero to four disk array frames (DKUs) To monitor and manage the array, a management server supplied by the customer is also required. The following figure shows the disk array with the maximum of four DKUs.
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 up to 128 disk drives for the XP24000 and contains up to 120 disk drives for the XP20000. DKC clusters As the following figure shows, power and PCBs in the DKC are organized into two independent and redundant clusters.
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” on page 41. 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 maintenance access to the system Hosts system management software...
Figure 6 Disk drive installation in the HDU box Figure 7 shows how the disk adapters connect to the HDUs in a fully expanded system. Figure 7 DKA and HDU interconnections RAID options The disk array supports RAID1 (2D+2D or 4D+4D), RAID5 (3D+1P or 7D+1P), and RAID6 (6D+2P) array groups.
Figure 8 Intermixed RAID groups Backup batteries The XP24000/XP20000 disk arrays use batteries and two modes of backup operation to provide backup power protection for cache memory, shared memory, the DKAs, CHAs, and disk drives. If AC input power is lost, the disk array continues normal operation for 200 ms or 1 minute, depending on whether the disk array is set for Backup Mode or De-stage Mode.
Figure 9 Battery de-staging and backup modes When AC power is restored, the disk array powers on again automatically if the AUTO POWER-ON jumper is set to ENABLE. If the jumper is set to DISABLE, the disk array must be manually powered on again using the control panel PS ENABLE and PS ON/OFF switches.

3 Operating the HP XP24000/XP20000 Disk Array 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.

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.
Managing the disk array The Remote Web Console software allows browser-based management of a single disk array. You can install the optional HP StorageWorks XP Array Manager software and the HP StorageWorks Command View XP Advanced Edition software on an optional management server to enable additional management capabilities, including the ability to manage multiple arrays.
Control panel and LED descriptions Once the disk array is powered on and running normally, no user operations are required at the control panel, except when you are instructed by your HP support representative. Figure 11 shows the control panel location and layout. Table 16 explains the control panel functions.

Item Label Indicator Description During normal operation, this LED should be off. ON: One or more of the following: DKC DC power is under voltage. DC power is over current. The temperature is abnormally high. SUB-SYSTEM An unrecoverable failure has occurred. If the disk LED (Red) ALARM array is set up for remote support, your HP support...
Item Label Indicator Description During normal operation, this LED should be on. ON: The disk array is plugged in and receiving power from the primary AC outlet. The SVP is receiving BS-ON power from the outlet. LED (Amber) OFF: The disk array is not receiving power from the primary AC outlet.
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.
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.
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. This indicates the system has produced a service information message because of the power outage.

4 Troubleshooting the HP XP24000/XP20000 Disk Array 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 as explained below. You can view SIMs using the system's management software.
Figure 13 Failure reporting process 1. A failure is detected in the system. 2. The failure is reported to the system. 3. The system stores the failure information in the system log. 4. The generated SIMs are stored on the system for use by HP technical support representatives, and logged on the management server as remote SIMs (R-SIMs).
