Replacing a Failed Disk Drive

This procedure describes how to replace a failed disk drive.

Before you begin to replace a disk drive in the drive module, gather antistatic protection
and the replacement disk drive.

C

AUTION

Possible loss of data access

– Never insert disk drives into an drive module

without first confirming the disk drive firmware level is compatible. Inserting
a disk drive with an incorrect firmware level can cause data loss or data
corruption. For information about supported disk drive firmware levels,
contact a Customer and Technical Support representative.

C

AUTION

Possible loss of data access

– Magnetic fields will destroy all data on a disk

drive and cause irreparable damage to the disk drive circuitry. To avoid loss
of data access and damage to disk drives, always keep disk drives away from
magnetic devices.

I

MPORTANT

Install only disk drives specifically designed for your drive module, and
that have been tested and qualified by the factory.

C

AUTION

Possible hardware damage

– To prevent electrostatic discharge damage to

the drive module, use proper antistatic protection when handling
components.

1

Put on antistatic protection.

2

Unpack the new disk drive.

Set the new disk drive on a dry, level surface near the drive module. Save all packing
materials in case you need to return the disk drive.

3

Remove the failed disk drive from the drive module.

shows how to remove

a disk drive.

a

Pull the drive handle to the left.

b

Use the handle to pull the disk drive out of the slot.

c

Put the disk drive on an antistatic, cushioned surface away from magnetic fields.
