5.5	Power Off Procedure

i

If you wish to power down the subsystem, please follow these steps:

NOTICE!

If you wish to power down the subsystem, please ensure that no time-consuming processes, like “Regenerate Logical Drive Parity” or a “Media Scan,” are running.

1.Stop I/O access to the system

Stop all I/O accesses from the host computers to the subsystem. Please refer to the related documentation of your host applications and operating system.

2.Disconnect the host

The host must be disconnected from the subsystem. To do this, disconnect the cables from both the host and the subsystem.

3.Flush the cache

Use the “Shutdown Controller” function to flush all cached data. This prepares the RAID subsystem to be powered down.

4.Turn off the power

Turn off the power switches at the power supply modules. Once the RAID subsystem has been powered down, other devices that are connected to the subsystem can be powered down.
