Using System Commands

Occasionally you may encounter a problem or situation in which you need to shut down the

Xserve RAID system or restart one of the RAID controllers or coprocessors. These system

commands are located in the System menu of RAID Admin.

The system commands include

m Shutdown, which shuts down the system completely. When you shut down the system

the data held in a cache is written on a disk before the system powers off.

Note: Use the Shutdown command if the Xserve RAID system will be turned off for more

than 72 hours. Shutting down with this command turns off the system and the optional

cache backup batteries. If you turn off the system using the power button, the cache

backup batteries remain on and could become discharged.

m Power Up, which starts up the system when it is in standby mode.

m Restart the Upper or Lower RAID Controller.

m Restart the Upper or Lower Management Coprocessor.

Note: Use the Restart system commands with care, because any of them may disrupt the

orderly transmission and storage of data.

Turning the System Identifier On or Off

You can use RAID Admin to turn on the system identiﬁer light should you want to locate a

particular Xserve RAID system or assist another administrator in ﬁnding that system. You can

also turn off the system identiﬁer when it’s on.

To turn the system identifier on or off:

1 Choose Toggle Service ID from the System menu.

2 Enter the management password and click OK.

This command turns the system identiﬁer on when it’s off or off when it’s on.
