To protect your user's security, neither edition of HP Command View software for the Device Manager server (CVXP or CVXP AE) has access to any user data stored on the disk array. There is no single point of failure in the disk array. It is designed with redundant logic assemblies, disk drives, and the power supplies, all of which can be removed or replaced without interrupting access to your data. Caution Only your HP service representative can remove or replace hardware. 56 HP StorageWorks Disk Arrays XP128/XP1024 Owner's Guide Control panel Figure 11 and Table 11 on page 58 show the control panel and its functions, respectively. 4 1 2 3 U 5 6 SUB-SYSTEM RESTART REMOTE MAINTENANC E PROCESSING READY ALARM MESSAGE ENABLE DISABLE STORAGE CLUSTER1 A B C D 7 7 7 7 8 8 8 8 9 10 L E U L J U L N U L STORAGE CLUSTER2 A U L E U L J U L N U L BS-ON PS-ON POWER SW ENABLE ON F G H K L M P Q R B C D F G H K L M POWER REMOTE P Q R LOCAL LED TEST 14 OFF CHK RST 15 11 13 12 EMERGENCY UNIT EMERGENCY POWER OFF Figure 11.

Control panel functions Item Label Indicator Description 1 SUBSYSTEM READY LED (Green) Indicates that input/output operation on the channel interface is enabled. If the LED is off, the system is not accepting data. Indicates DC under voltage, DC over current, abnormally high temperature, or an unrecoverable failure has occurred. If your disk array is set up to report messages to the remote center, your HP service representative is notified automatically. If your disk array is not setup to report messages to the remote center, you should place a service call to HP to have the message evaluated to determine if any action is required. ON: Indicates a message has been issued from either Cluster. If your disk array is set up to report messages to the remote center, your HP service representative is notified automatically. If your disk array is not set up to report messages to the remote center, you should place a service call to HP to have the message evaluated to determine if any action is required. Blinking: Indicates the internal service processor has experienced a failure. The disk array will continue to operate normally. You should place a service call to HP to ensure notification. Service processor failures may not be reported automatically to the remote center. 2 SUBSYSTEM ALARM LED (Red) 3 SUBSYSTEM MESSAGE LED (Amber) 4 SUBSYSTEM RESTART Switch Used to unfence the fenced drive path and to release Write Inhibit. There is a blocked path somewhere between a host and a disk drive. By restarting the subsystem, a soft reset will be performed to try to recover. If system restart does not unblock the path, an HP service representative will be notified. Indicates remote maintenance is being processed. An HP service representative may be working on your system, but the system is online and accepting data. 5 REMOTE MAINTENANCE PROCESSING LED (Amber) 58 HP StorageWorks Disk Arrays XP128/XP1024 Owner's Guide Table 11. [. . . ] A parity group is a disk configuration in which multiple disks work together to provide redundancy. Synonymous with "array group. " Dividing a specific physical disk into two or more areas as if there are two or more physical disks. Paths are created by associating a port, a target, and a LUN ID with one or more LDEVs. Power control interface or peripheral component interconnect. [. . . ]
