Removing a SSA Disk Drive from Bank C, D, or E
Notes:
To locate banks C, D, and E, see the illustration given on page 5-81.
You do not have to turn off the server to remove a drive from banks C, D,
and E.
The lights on the disk drive provide status of the drives. See “Disk Drive Status LED
States” on page 2-18 for a definition of the disk drive status.
Attention:
An application procedure unique to your operating system must be followed which
logically removes the drive from the system and spins it down. If you remove a
drive while it is in use, your system may lose valuable data.
