Restoring an Entire Cluster

Task 10: Re-create the Cluster

To re-create the cluster, run the clu_create command:

# clu_create

 

 

 

For more information about installing the cluster, refer to the TruCluster

 

 

 

documentation.

 

 

 

 

 

 

Note: Do not reboot after running clu_create. Remain in stand-alone HP Tru64

9

 

 

mode.

 

 

 

 

 

 

Task 11: Recover the Cluster Data

 

 

 

To recover the cluster data:

 

 

 

 

 

 

1. Mount the root, usr, and var cluster directories:

 

 

 

# mount cluster_root#root /mnt

 

 

 

# mount cluster_usr#usr /mnt/usr

 

 

 

# mount cluster_var#var /mnt/var

 

 

 

where /mnt is the mount point.

 

 

 

2. Restore the cluster data using the recover command in interactive mode,

 

 

 

as shown in the following example.

 

 

 

Note: The force option is used in this step so that the recovered files

 

 

 

overwrite the existing files.

 

 

 

# recover -ccluster_default_alias

 

 

 

recover> cd /

 

 

 

recover> add .*

 

 

 

recover> add *

 

 

 

recover> delete /devices /dev

 

 

 

recover> cd /etc

 

 

 

recover> delete dec* dccd* dcdd* ddr*

 

 

 

recover> delete disktab dvrdevtab gen* dfsc*

 

 

 

recover> cd /cluster/members/member0

 

 

 

recover> delete boot_partition dev devices

 

 

 

recover> delete etc/ddr*

 

 

 

recover> delete etc/gen*
