Page 24: General Safety Guidelines
General safety guidelines Read the following safety guidelines carefully and follow them when you work with the HP StorageWorks Disk Array XP128 disk array. • Remember that the maintenance of your machine must be done only by trained and qualified HP field engineers. Only an HP service representative can power off the disk array in a non-emergency situation.
Page 25 • Do not power off the system unless it is an emergency power-off situation. • Keep the front and rear doors closed at all times. • Keep the tops and sides of the cabinets clear to allow air to flow properly.
Page 26: Physical Components

Page 36: Normal Operations
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.
Page 37: Powering Down The Disk Array
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.
Page 38 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.
Page 39: Recovering From A Power Outage To The Disk Array
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.
Page 40: 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). If your site does not have a...

Normal operations The disk array does not require intervention from the user. The disk array reports any remote system information messages (R-SIMs) to your Device Manager server running HP Command View XP or Command View XP Advanced Edition. The internal disk array service processor also sends the report to the HP Service Center automatically.
Page 65: Powering Down The Disk Array
Powering down the disk array Situations may arise in the operation of the disk array that require the user 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.
Page 66: Planned Power-Off
Planned power-off There may be times when a site power outage is planned, such as to make alterations to the data center, do inspections, or to allow work by the electric company. If a scheduled power outage affects an HP Disk Array XP1024, the power down of the disk array must be scheduled with a trained HP support representative.
Page 67: Recovering From A Power Outage To The Disk Array
Recovering from a power outage to the disk array If a power outage to the array occurs, 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. This length of time will provide coverage for most outages.
Page 68: Manual Restart Of The Disk Array After Power Is Restored
Manual restart of the disk array after power is restored Caution Before restoring power to the disk array, HP recommends that an electrician check the input power to ensure it is stable and clean. You may call a trained HP representative or you may use the following procedure yourself to recover the disk array from a power failure: 1.
Page 69: Automatic Power On Restart
Automatic power on restart Caution As with all sophisticated electronic equipment, unstable power conditions during a restart can induce problems. HP recommends automatic power on restart only when power to the disk array is conditioned to ensure it is stable, such as by using a UPS. If your site does not have a UPS, HP recommends the disk array be configured for manual restart by keeping the ENABLE/DISABLE switch in the DISABLE position and using the manual restart procedure when power has been restored and verified.
