Powering off disk enclosures
IMPORTANT:
Always power off disk enclosures after controller enclosures and servers.
IMPORTANT:
When installing a hot-pluggable component, such as a disk drive, it is not necessary to power down
the enclosure.
To power off a disk enclosure:
1. Power off any attached servers. For more information, see the server documentation.
2. Power off the controller enclosure (if included in the configuration.) For more information, see the
controller enclosure documentation.
3. Power off the disk enclosures. Press and hold the power on/standby button on the disk enclosure
for three seconds or until the system power LED changes from green to amber.
4. Disconnect power cords.
The system is now without power.
Updating disk enclosure firmware
After initial installation and periodically after that, verify that all devices in the configuration have the
latest available firmware installed.
To determine currently-installed firmware and software versions on system components, use
management software utilities such as the HP System Management Homepage, HP Systems Insight
Manager (HP SIM), Storage Management Utility (SMU), or Command Line Interface (CLI).
To obtain the latest-available firmware and software, see the HP website: http://www.hp.com/
support.
To perform the update, follow the procedures for your environment:
• For server connect environments, execute the downloaded Smart Component using the Firmware
Maintenance CD.
• For controller enclosure connect environments, install the firmware download using the Storage
Management Utility (SMU) or Command Line Interface (CLI).
