Powering Off Or Rebooting The Storage System; Powering On Or Off, Or Rebooting Storage Systems With Modular Components - HP StoreVirtual 4000 User Manual

Powering off or rebooting the storage system

Reboot or power off the storage system from the CMC. Set the amount of time before the process
begins, to ensure that all activity to the storage system has stopped.
Powering off the storage system through the CMC physically powers it off. The CMC controls the
power down process so that data is protected.
Powering off an individual storage system is appropriate for servicing or moving that storage
system. However, if you want to shut down more than one storage system in a management group,
you should shut down the management group instead of individually powering off the storage
systems in that group. See
IMPORTANT:
Before powering off or rebooting the storage system, ensure that volumes will not go offline
by checking the storage system Availability tab. See
availability " (page
You should also verify that you have the proper number of managers and possibly a Failover
Manager to ensure that quorum is maintained. See

Powering on or off, or rebooting storage systems with modular components

Some storage systems are comprised of modular components, that may include:
Disk enclosure
Server blades enclosure
System controller
The P4800 is an example of a storage system that is comprised of modular components.
Power on the components in the following order:
1. Disk enclosure.
2. Server blades enclosure or system controller.
Allow up to 6 minutes for the system controller to come up completely and be discovered by
the CMC. If the CMC cannot find the storage system after 6 minutes, contact Customer Support.
3. If you do not power on the disk enclosure first, the Storage System Details tab shows the status
with No Formatted Devices Available.
