Chapter 7
Drive Enclosure Component Replacement
Procedures
This chapter describes the replacement of each component in the drive enclosure, in the
event of a component failure.
Use the following procedure when instructed by the storage management software
(TPSSM7) to replace a failed drive sled.
Before starting this procedure, read "Drive Sled" on page 77.
Caution: Electrostatic discharge can damage sensitive components. Use a grounded
wrist strap or other antistatic precautions before handling drive enclosure components.
1. Check the storage management software (TPSSM7) for instructions on drive failure
recovery procedures. Follow any steps given in the software procedure before
continuing with this procedure.
Caution: Removing the wrong drive can cause data loss. Make sure you remove
only the failed drive sled. The drive Fault indicator should be on (amber) above the
failed drive sled.
Removing a drive sled while its green Activity indicator is blinking can cause data
loss and may cause the host controller to mark the drive as failed. If you remove an
active drive accidentally, wait at least 30 seconds and then reinstall it. Refer to the
storage management software (TPSSM7) for further recovery instructions.
2. Locate the failed drive sled (its fault light should be on).
