The disk array reports any remote error messages (R-SIMs) to your remote console PC and also sends the report to the HP Service Center automatically.

For more information on SIMs, see "Troubleshooting" (page 77). The HP SureStore E Disk Array XP48 Hardware 57 Powering Off the Disk Array Situations may arise in the operation of the disk array that require the user to power off the disk array. These situations include: · UNIT EMERGENCY POWER OFF · Planned power-off UNIT EMERGENCY POWER OFF An emergency is a critical situation such as a physical plant catastrophe such as a flood, hurricane, tornado, or a threat of injury or death to a person.

The disk array UNIT EMERGENCY POWER OFF switch is located on the control panel. Caution Use this switch only in case of an emergency. An HP Service Representative is required to reset the UNIT EMERGENCY POWER OFF and to power on the disk array. Pull the UNIT EMERGENCY POWER OFF switch (figure 10 (page 56)) up and then out toward you as illustrated on the switch. The UNIT EMERGENCY POWER OFF switch must be reset by an HP Service Representative before the disk array can be powered on again. 58 HP SureStore E Disk Array XP512/XP48: Owner's Guide Planned Power-Off There may be times when a site power outage is planned. These situations would include alterations to the data center, inspections, or work by the electric company. If a scheduled power outage affects an HP SureStore E Disk Array XP48, the power off of the disk array must be scheduled with a trained HP support representative. 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. The HP SureStore E Disk Array XP48 Hardware 59 Recovering from a Power Outage to the Disk Array A power outage to the array is when the primary building power is lost due to electrical blackouts, thunderstorm activity, etc. , and input AC power is not received by the array. The disk array will maintain its state and recover when power is restored. The array cache is backed up by batteries that will maintain its state for a minimum of 48 hours. In cases where the outage will extend beyond 48 hours, the batteries can be replaced by an HP CE, which will extend the time, if necessary. Caution After power is restored to the customer site and before restoring power to the disk array, HP recommends verification of power by an electrician to ensure all phases are restored and input power to the disk is stable.
