PC Server 720 - Removing a drive from bank C,D,E
Applicable to: World-Wide
Removing a Drive from Bank C, D, or E
Locate the drive you are removing. You do not have to power-off the server to remove a drive from banks C, D, or E.
Warning
If you are removing a failed hard disk drive that is part of a disk array in bank C, D, or E, you must not accidentally remove a good drive. Before you attempt to remove a defective drive, thoroughly review the information displayed on your server's screen to determine the location of the failed drive. 'Logical and Hard Disk Drive Status Indications— explains the codes that your server uses to indicate a defective drive. When a hard disk drive fails, a blinking green indicator light illuminates on the knob of the drive tray. When a hard disk drive is good, a solid green indicator light illuminates on the knob of the drive tray.
If you partially or completely remove a good drive instead of the defective one, your server might lose valuable data. This situation is especially relevant if you assigned RAID level 1 or 5 to the logical drives in your disk array. However, the RAID controller can rebuild the data you need, provided that certain conditions are met. See 'Starting the RAID Configuration Program— for more details.
If you have a non-disk-array model, an illuminated drive tray knob means the drive is a good one. An unilluminated drive tray knob means the drive is defective, or no power is being supplied to the drive.
To remove a drive from bank C, D, or E, do the following:
1. Find the drive you plan to remove.
2. If you have a disk-array model and a drive has failed, ensure that you have selected the correct drive for removal by verifying that the light on the tray's knob is blinking.
3. Unlock the drive by turning the knob directly above it 90 degrees.
4. Disconnect the drive from the connector on the backplane, by grasping the handle on the drive tray and pulling the drive out of the server. Store the drive in a safe place.
Note
If you have a disk-array model, you must reconfigure your disk arrays after removing hard disk drives. See 'Starting the RAID Configuration Program— for details.
