6.3.3 Restoring

1) Stopping the services

1a) With a shared volume used by a cluster application.

Exit the cluster application.

1b) With a volume not used by a cluster application

1b-1) Stop the services using the volume.

1b-2) When the volume is used as a file system, unmount the file system. In the following example, the mount point is /mnt1.

# cd /
# umount /mnt1

 

2) Restoring

Restore the volume data. The following shows an example of restoring data from a tape medium of tape device /dev/rmt/0.

For details on the restore methods, see the manuals of file systems to be restored and used commands.

• When restoring data held in a raw device with the dd(1M) command

  # dd if=/dev/rmt/0 of=/dev/sfdsk/Class1/rdsk/Volume1 bs=32768

  
  

• When restoring a ufs file system with the ufsrestore(1M) command

  # newfs /dev/sfdsk/Class1/rdsk/Volume1
  # mount -F ufs /dev/sfdsk/Class1/dsk/Volume1 /mnt1
  # cd /mnt1
  # ufsrestore rvf /dev/rmt/0
  # rm /mnt1/restoresymtable
  # cd /
  # umount /mnt1

  
  

• When restoring the GFS Local File System with the sfxrestore(1M) command

  # sfxnewfs /dev/sfdsk/Class1/rdsk/Volume1
  # mount -F sfxfs /dev/sfdsk/Class1/dsk/Volume1 /mnt1
  # cd /mnt1
  # sfxrestore rvf /dev/rmt/0
  # rm /mnt1/restoresymtable
  # cd /
  # umount /mnt1

 

3) When the volume is used as the GFS Local File System, add the node configuration information of the GFS Local File System on a node where restore was not conducted.

3-1) Inactivate the volume on the node where restore was conducted.

# sdxvolume -F -c Class1 -v Volume1

3-2) Activate the volume on a node where restore was not conducted.

# sdxvolume -N -c Class1 -v Volume1

3-3) Add the node configuration information of the GFS Local File System on the node where restore was not conducted.

# sfxnode /dev/sfdsk/Class1/rdsk/Volume1

3-4) Inactivate the volume on the node where restore was not conducted.

# sdxvolume -F -c Class1 -v Volume1

 

4) Resuming the services

4a) With a shared volume used by a cluster application

Execute the cluster application.

4b) With a volume not used by a cluster application

4b-1) When the volume is used as a file system, mount the file system. In the following example, the mount point is /mnt1.

• For a ufs system

  # mount -F ufs /dev/sfdsk/Class1/dsk/Volume1 /mnt1

  
  

• For a GFS Local File System

  # mount -F sfxfs /dev/sfdsk/Class1/dsk/Volume1 /mnt1

4b-2) Resume the services.
