Chapter 7 FRU/CRU Replacement Procedures 7-37
Caution – Mixed configurations speed requirements. In configurations involving
various models of command modules, command modules, or drive modules, all
modules must be operating at the same speed. Refer to the Product Release Notes for
any model-specific restrictions.
Caution – Risk of data loss and permanent damage. Magnetic fields will destroy all
data on a disk drive and cause irreparable damage to its circuitry. To prevent data
loss and damage to disk drives, always keep drive modules and drives away from
magnetic devices.
1. Use the storage management software to create, save, and print a new storage
array profile.
2. Did the Recovery Guru direct you to replace a failed dri ve?
■Yes - Go t o ste p 3.
■No - Run the Recovery Guru to identify the failed component,
and then go to step 3.
3. Remove the back cover
4. 4 If needed, mute the alarm.
Caution – Electrostatic discharge damage to sensitive components. To prevent
electrostatic discharge damage to the module, use proper antistatic protection when
handling the module components.
5. 5 Put on antistatic protection.
Caution – Potential damage to drives. Bumping disk drives against another surface
can damage the drive mechanism or connectors. To prevent damage when removing
or installing a drive, always place your hand under the drive to support its weight
6 Unpack the new drive.
Set the new drive on a dry, level surface, away from magnetic fields. Save all
packing materials in case you need to return the drive.
Potential data loss. Removing a drive that has not failed can cause data loss. To
prevent data loss, remove only a failed drive that has a Fault (amber) light on or a
Failed status in the storage management software.
