Powering Off Disk Enclosures; Updating Disk Enclosure Firmware - HP StorageWorks D2700 User Manual

Powering off disk enclosures

CAUTION:
Be sure that the server is the first unit to be powered down and the last to be powered back up. Taking
this precaution ensures that the system does not erroneously mark the disk drives as failed when the
server is powered up.
IMPORTANT:
If installing a hot-plug device, it is not necessary to power down the enclosure.
To power off a disk enclosure:
1. Power down any attached servers. See the server documentation.
2. Power down the disk enclosures. Press and hold the power on/standby button on the rear of the
disk enclosure for three seconds or until the system power LED changes from green to amber.
3. Disconnect the power cords.
The system is now without power.

drives are running on the latest available firmware. You can identify currently installed firmware
versions through the HP SIM and ACU software utilities.
Firmware updates on the controller, disk enclosure and disk drives, are performed using HP Smart
Components. For more information, see
IMPORTANT:
Before installing new firmware on the disk enclosure, be sure to study the release notes and installation
instructions provided with the firmware.
