CAUTION: Performing an emergency power off immediately shuts down the system, neglecting the normal power off sequence. Jobs in process are aborted and their integrity after recovery is not guaranteed. Use this power off method only in an emergency. Afterwards, only a qualified HP support representative is allowed to restore power to the system. Call your HP support representative immediately. Emergency situations in which you should consider performing the emergency power off procedure are: · A physical location catastrophe such as a flood, hurricane, tornado, or earthquake · Any circumstance that presents the threat of injury or death to a person · You detect any smoke, abnormal loud noise, or smell coming from the system. 38 Operations 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 system, 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 system. Do not attempt to power down the system other than during an emergency. HP StorageWorks 200 Storage Virtualization System owner's guide 39 Recovering from an unplanned or emergency power outage Unplanned power outages occur when the primary building power is lost due to electrical blackouts, thunderstorm activity, or similar occurrences, and input AC power is not received by the system. The system will maintain its state and recover when power is restored. The system cache is powered by backup batteries that will maintain the system state for up to 36 hours, depending on the selected battery operation mode. For restart procedures after power is restored to the system, see the following text about manual and automatic restart of the system. If the length of a power outage exceeds the cache battery backup time, contact HP for assistance with recovery. 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 system manually: 1. On the control panel, move the PS ENABLE switch to the ENABLE position. Move the PS ON/OFF switch to the ON position. The following LED power sequence occurs: BS-ON turns amber. MESSAGE LED may turn amber if the system is not configured to "phone home, " signifying a SIM was generated because the system lost power unexpectedly. READY LED turns green, signifying the system is ready. 40 Operations CAUTION: Power on can take several minutes and is not complete until the READY LED turns green. Move the PS ENABLE switch to "DISABLE" (opposite the ENABLE position). HP StorageWorks 200 Storage Virtualization System owner's guide 41 Automatic restart when power is restored CAUTION: HP recommends the use of automatic power on restart only if the power to the system is subject to power conditioning equipment, such as a UPS, to ensure that the power restored to the system is stable. [. . . ] Synonymous with "array group. " Dividing a specific physical disk into two or more areas as if there are two or more physical disks.
