How to Restore Individual Files Interactively (Solstice DiskSuite/Solaris Volume Manager)

Use this procedure to restore one or more individual files. Be sure the cluster is running problem-free before performing the restore procedure.

Become superuser on the cluster node you want to restore.

Stop all the data services that are using the files to be restored.
# scswitch -z -g resource-group[,...] -h ““

Restore the files using the ufsrestore command.

How to Restore the root (`/`) File System (Solstice DiskSuite/Solaris Volume Manager)

Use this procedure to restore the root (/) file systems to a new disk, such as after replacing a bad root disk. The node being restored should not be booted. Be sure the cluster is running problem-free before performing the restore procedure.

Note –

Since you must partition the new disk using the same format as the failed disk, identify the partitioning scheme before you begin this procedure, and recreate file systems as appropriate.

Become superuser on a cluster node with access to the metaset, other than the node you want to restore.

Remove from all metasets the hostname of the node being restored.

Run this command from a node in the metaset other than the node you are removing.
# metaset -s setname -f -d -h nodelist
-s setname

Specifies the diskset name.

-f

Force.

-d

Deletes from the diskset.

-h nodelist

Specifies the name of the node to delete from the diskset.

Replace the failed disk on the node on which the root (/) file system will be restored.

Refer to disk replacement procedures in the documentation that came with your server.
