Shutting down the storage system
After collecting drive serial numbers, a clean power down of the Hitachi
Unified Storage 130 storage system (CBSS or CBSL) from the main power
off switch is required. The clean power down must be performed from the
main Power Off switch on Controller #0 or Controller #1. Do not power
down using the power cables.
1. Confirm the following:
-
Do not power off the storage system if the green READY LED on
the front of the Controller Box is blinking quickly (it can remain
blinking up to 50 minutes).
-
If the Power Saving option is used, initiate a spin-down, and then
power off the storage system before spin-down completes, the
spin-down may fail. Therefore, wait for spin-down to complete
before powering off the storage system.
Confirm that no RAID Group has a power saving status of Normal
(command monitoring) after executing the spin-down.
If the spin-down fails, perform the spin-down again.
-
Confirm that there are no drives whose status is Blocked. If there
are, resolve the block before powering off the storage system.
