4.15 Power-Off Procedure
You might need to power off the array (both power supplies) if you relocate the array
or perform certain maintenance procedures with associated servers. Always shut down
the array’s controller before powering off the array.
Caution –
If controllers are not shut down from the firmware application or the CLI
before an array is powered off, data that is written to cache and that has not been
completely written to the disks will be lost.
To power off an array, perform the following steps:
1. Stop all I/O activity to the array.
2. Shut down the controller with one of the following commands:
■
Firmware application Shutdown Controller command ( system Functions
→
Shutdown controller )
■
SANscape CLI
shutdown controller
command
These commands first halt all I/O activity, and then write the contents of cache to the
drives.
3. Power off both power supply/fan modules.
See “Power-On Sequence” on page 4-30 for information about turning the array on
again.
