Normal operations The disk array does not require user intervention. The disk array automatically reports any remote system information messages (R-SIMs) to your Device Manager server running HP Command View XP or Command View XP Advanced Edition, to the internal disk array service processor, and also to the HP Service Center. For more information on SIMs, see Chapter 5, "Troubleshooting" on page 87.
Powering down the disk array Situations may arise in the operation of the disk array that require you to power down the disk array. These situations include: • Emergency power-off • Planned power-off Emergency power-off An emergency is a critical situation such as a physical plant catastrophe. In an emergency, the critical need is to quickly remove power from the disk array. A quick restart is not necessary. In an emergency, the operator should trip the Emergency Power-Off (EPO) switch.
Caution Only a trained HP representative can shut down and power-off a disk array. Shutting down and powering off a disk array is not a customer activity. A user should not attempt to power down the disk array at any time other than an emergency. When planning for your planned power outage, please contact your HP CE to schedule a customer visit.
Recovering from a power outage to the disk array If AC input power is lost, the disk array maintains its state and recovers when power is restored. The array cache is backed up by batteries that will maintain its state for a minimum of 48 hours. This length of time will provide coverage for most outages. In cases where the outage will extend beyond 48 hours, the batteries can be replaced by a HP to extend the time, if necessary.
Automatic power on restart Caution As with all sophisticated electronic equipment, unstable power during a restart can induce problems. Hewlett-Packard recommends automatic power on restart only when the power to the disk array is conditioned to ensure stability (for example, using a UPS).

Glossary ACP Array control processor. The ACP handles the passing of data between the cache and the physical drives held in the DKUs. ACPs work in pairs, providing a total of eight SCSI buses. Each SCSI bus associated with one ACP is paired with a SCSI bus on the other ACP pair element. In the event of an ACP failure, the redundant ACP takes control. Both ACPs work together sharing the load. AL Arbitrated loop. AL-PA Arbitrated loop physical address.
C-Track The HP StorageWorks Continuous Track XP software program, which detects internal hardware component problems on a disk array and automatically reports them to the HP STC. CA The HP StorageWorks Continuous Access XP program, which enables you to replicate data stored on a local disk array to a remote disk array. cache Very high speed memory that is used to speed I/O transaction time. All reads and writes to the XP array family are sent to the cache.
CU Control unit. CVS Custom volume size. CVS devices (OPEN-x CVS) are custom volumes configured using array management software to be smaller than normal fixed-size OPEN system volumes. Synonymous with volume size customization (VSC). disk adapter (DKA) Synonymous with the term ACP. disk unit (DKU) The array hardware that houses the disk array physical disks. disk controller (DKC) The array hardware that houses the channel adapters and service processor (SVP).
The LUSE feature is available when the HP StorageWorks LUN Configuration Manager product is installed. ExSA Extended serial adapter. failover Disconnecting a failed unit or path and replacing it with an alternative unit or path in order to continue functioning. FC Fibre Channel.

LED Light emitting diode. local disk A disk in the host. LU Logical unit. LUN Logical unit number. A LUN results from mapping a SCSI logical unit number, port ID, and LDEV ID to a RAID group. The size of the LUN is determined by the emulation mode of the LDEV, and the number of LDEVs associated with the LUN. For example, a LUN associated with two OPEN3 LDEVs has a size of 4,693 MB. LUSE Logical unit size expansion. See also Expanded LUN. m Meters. MB Megabytes. MCU Main control unit.
OS Operating system. PA Physical address. parity group A parity group is a disk configuration in which multiple disks work together to provide redundancy. Synonymous with “array group.” partition Dividing a specific physical disk into two or more areas as if there are two or more physical disks. path Paths are created by associating a port, a target, and a LUN ID with one or more LDEVs. PCI Power control interface or peripheral component interconnect.
