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.
