6.2 Identifying a defective drive
The red LED on the OLR housing identifies a disabled drive which can be replaced.
You can identify the defective drive with the aid of XConfig (on a graphical terminal)
or SYSADM (on an alphanumeric terminal). Under XConfig, defective or disabled
drives are shown in red; under SYSADM, an error messages appears for each
defective or disabled drive.
Another way of identifying defective drives is to use the RAIDmaster Storage Manager
(see the “RAIDmaster - System Administrator’s Guide”).

To use XConfig you need a graphical monitor.
