Overview of the HP XP10000 Disk Array
2 HP XP10000 hardware components There are no single points of failure in HP XP10000 disk arrays. Redundant logic assemblies, controllers, disk drives, and power supplies can be removed or replaced without interrupting access to data. This section describes individual physical components of the disk array. See Figure 1 on page 13 for an overview of the disk array hardware. CAUTION: Only your HP support representative can remove or replace hardware.
Figure 2 HP XP10000 control panel components Table 3 HP XP10000 control panel components Item Label Indicator Description During normal operation, this LED should be on. 1 READY LED (Green) ON: Input/output on the channel interface is enabled. OFF: The system is not accepting data. During normal operation, this LED should be off. ON: One or more of the following: The DC is under voltage. The DC is over current. The temperature is abnormally high.
Item Label Indicator Description During normal operation, this LED should be off. 3 MESSAGE LED (Amber) ON: A service information message (SIM) has been issued from either storage cluster. If the disk array is set up for remote support, your HP support representative is notified automatically. If the disk array is not set up with remote support, place a service call to HP to have the message evaluated to determine if any action is required. BLINKING: An SVP failure has occurred.
Item Label Indicator Description During normal operation, this LED should be on. 7 BS-ON LED (Amber) ON: The disk array is plugged in and receiving power from the primary AC outlet. The SVP is receiving power from the outlet. OFF: The disk array is not receiving power from the primary AC outlet. Check the electrical outlets in your building. During normal operation, this LED should be on. 8 PS-ON LED (Green) ON: The PS ON/OFF switch is on.
The disk array must contain at least one spare disk drive and can contain up to 16. Any of the spare disk drives can back up any other disk drive of equal rotational speed and equal or lesser capacity, in any disk chassis, even if the failed disk and the spare disk are in different array domains. The XP10000 disk array supports 73 GB, 146 GB, 300 GB and 400 GB Fibre Channel disk drives.

3 HP XP10000 operations During normal operations, the disk array does not require 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 on SIMs, see “Service information messages” on page 33.
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.
Emergency power off The system does not have an emergency power off switch. In an emergency when it is crucial to power off the system immediately for safety reasons, remove power at the AC branch circuit breakers in your facility that supply power to the system. Take care when placing these breakers that they are clearly marked and easily accessible. CAUTION: Performing an emergency power off immediately shuts down the system, neglecting the normal power off sequence.
Manual restart after power is restored CAUTION: After power is restored to your site and before restoring power to the system, HP recommends that you have an electrician verify the power to ensure that all phases are restored and input power is stable. Before you power on the system, power on any external disk array(s) first and make sure they are operating properly. For assistance recovering from a power outage, contact your HP support representative. To restart the disk array manually: 1.
PS-ON turns green. MESSAGE LED may turn amber if the system is not configured for remote support, signifying a SIM was generated because the system lost power unexpectedly. READY LED turns green, signifying the system is ready. CAUTION: Powering on the disk array can take several minutes. Power on is complete only when the READY LED turns green. Operating specifications This section provides some general specifications.
Humidity range type Non-condensing relative humidity (RH) Non-operating maximum wet bulb temperature 27 degrees C (81 F) Shipping and storage maximum wet bulb temperature 29 degrees C (84 F) Mechanical vibration Continuous vibration can cause a slow degradation of mechanical parts and, when severe, can cause data errors in disk drives. Mechanical connections such as printed circuit assembly (PCA) conductors, cable connectors, and processor backplane wiring can also be affected by vibrations.
4 HP XP10000 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 34 Description If the system is set up for remote support, HP XP Continuous Track reports the SIMs to STC through a dedicated dialup 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.
