3.6.5 Restoring the Resource Database

The procedure for restoring the Resource Database is as follows:

1. Copy the file containing the Resource Database to all nodes in the cluster.

2. Log in to each node in the cluster and shut it down with the following command:

   #/usr/sbin/shutdown -y -i0

3. Reboot each node to single user mode with the following command:

   {0} ok   boot -s

   Note

   The restore procedure requires that all nodes in the cluster must be in single user mode.

4. Reboot each node to single user mode with the following command:

   # mountall -l 
   # zfs mount -a 

5. Reboot each node to single user mode with the following command:

   # clrestorerdb -f file

   file is the backup file with the .tar.Z suffix omitted.

   For example, suppose that a restoration was being done on a two-node cluster consisting of nodes fuji2 and fuji3, and that the backup file was copied to /mydir/backup_rdb.tar.Z on both nodes. The command to restore the Resource Database on fuji2 and fuji3 would be as follows:

   fuji2# cd /etc/opt/FJSVcluster/bin/
   fuji2# ./clrestorerdb -f /mydir/backup_rdb.tar.Z
   fuji3# cd /etc/opt/FJSVcluster/bin/
   fuji3# ./clrestorerdb -f /mydir/backup_rdb.tar.Z

6. After Steps 1 through 5 have been completed on all nodes, then reboot all of the nodes with the following command:

   #/usr/sbin/shutdown -y -i6
