Replacing a Hard Drive

The following sections provide important information to be aware of when replacing a hard drive as part of a disaster recovery:

• “Prerequisites” on page 27

• “Replacing the Hard Drive” on page 27

• “Completing the Recovery Process” on page 28

Prerequisites

To help ensure that you are prepared to replace and reconfigure a hard drive,
maintain a current record of the system information. Obtain the following
information using the appropriate operating system commands:		3
•	Size of the drive
•	Filesystem volume information
• Volume label assigned to each disk partition
• How the disk is partitioned
• How the disk is loaded
• The size of the disk
• Each logical volume (size and label)
•	Each filesystem

Note: Though it does not affect NetWorker operation, you could also note any use of mirroring, Redundant Array of Independent Disk (RAID), striping, compression, or volume sets.

Replacing the Hard Drive

If one or more hard drives fail, refer to the appropriate operating system documentation and hard drive vendor documentation for detailed instructions on how to replace the hard drives.

Important: To ensure that you can recover all of the drive’s data, install a new drive that is the same size or larger than the original drive.
