Chapter 9: HP TruCluster Disaster Recovery

If you need to remap device numbers, use the -eoption with the following command:

#dsfmgr -e dsk10 dsk4

where dsk10 is the new disk enumeration value and dsk4 is the original disk enumeration value.

Alternatively, if you want to move a device number, use the -moption.

# dsfmgr -m dsk10 dsk4

Task 4: Install the NetWorker Software

Perform this task if the NetWorker server was installed as a highly available cluster application. If the NetWorker server is outside the cluster, skip this task and proceed to “Task 9: Recover the Server’s Client File Index” on page 149.

To install NetWorker software:

1.Install the same version of the NetWorker server software. When prompted during the installation, enter the location of the /nsr directory as follows:

/nsr

For more information about installing NetWorker software, refer to the appropriate Legato NetWorker Installation Guide.

2.Install any NetWorker patches that were installed prior to the disaster.

3.If separate filesystems were created for the subdirectories under the original /nsr directory, mount those filesystems under this /nsr directory. Separate filesystems may have been created for subdirectories, such as /nsr/mm or /nsr/index, that became very large.

4.Re-create the cluster’s /nsr directory:

#mkdir -p /cluster_default_alias/nsr

#cd /cluster/members/member0

#ln -s /cluster_default_alias/nsr nsr

#cd /cluster/members/member1

#ln -s /cluster_default_alias/nsr nsr
