Legato NetWorker, Release 7.0

Disaster Recovery Guide

Disaster Recovery of Clustered Computers

For disaster recovery of a computer that was running NetWorker software in

a cluster environment, see the appropriate chapter for procedures:

• “Chapter 6: Microsoft Cluster Disaster Recovery (Windows NT 4.0)”

• “Chapter 7: Microsoft Cluster Disaster Recovery (Windows 2000 and

.NET)”

Replacing a Hard Drive

Important: To ensure that you have enough disk space to recover all of the

failed hard drive’s data, install a new hard drive with at least as much storage

capacity as the original drive.

Recovery of the SYSTEM save sets requires extra disk space for temporary

files. The recovery operation might require as much extra disk space as the

total size of the SYSTEM save sets. For an estimate, run mminfo from the

command prompt and check the size of the SYSTEM save sets. In many cases,

about 500 MB of temporary disk space is sufficient.

To replace the failed hard drive, the following information is required:

• The storage capacity of the hard drive being replaced, plus the amount of

extra disk space required for temporary files

• The drive letter, size, format, and volume label assigned to each partition

on the hard drive being replaced:

Windows .NET, Windows XP Professional, and Windows 2000 — This

information is available in Control Panel > Administrative Tools >

Computer Management > Disk Management.

Windows NT 4.0 — This information is available in Start > Programs >

Administrative Tools (Common) > Disk Administrator.

Note: Although it will not affect NetWorker operation, you may also want to

note any use of mirroring, RAID/striping, compression, or volume sets.

Install, partition, and format the new hard drive. For instructions, refer to the

hard drive manufacturer’s documentation and the appropriate Microsoft

documentation.
