    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.

  • Page 20: Disk Control Frame

    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.

PS REMOTE/ REMOTE: Disk array is powered on/off by the instructions Switch of the host PCI (mainframe only).

  • Page 25: Disk Drives

    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. Any of the spare disk drives can back up any other disk drive of equal rotational speed and equal or lesser capacity, in any DKU, even if the failed disk and the spare disk are in different array domains.

  • Page 26: Optional Management Server

    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;...

    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.

  • Page 28: Powering Down The Disk Array

    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.

  • Page 29: Planned 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. CAUTION: Only a trained HP support representative can shut down and power off the disk array.

  • Page 30: Recovering From An Unplanned Power Outage

    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.

  • Page 31: Automatic Restart When Power Is Restored

    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.

    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.
  • Page 36 Item 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.
