• Create snapshot copies of volumes and then back up the volumes.
• Reorganize the space occupied by volumes (by moving subdisks to
other disks).
These tasks are described in Chapter 4, Volume Tasks.
To maintain file systems
• Place additional file systems on volumes.
• Increase the size of file systems as users and applications require
more space.
• Create snapshot copies of vxfs file systems and then back up the file
systems.
These tasks are described in Chapter 4, Volume Tasks.
Repair/Recovery Tasks
If disk and/or system failures occur, the Volume Manager may perform
any necessary recovery operations automatically. However, depending on
the circumstances, you may need to attempt to recover from the situation
as follows.
To protect volumes from disk failure
• Evacuate a failing disk.
• Replace a failed disk.
These tasks are described in Chapter 3, Disk Tasks.
To repair/recover volumes
• Recover a volume.
• Recover all volumes on a failed disk.
• Recover all volumes in a disk group.
• Start a volume.
• If a volume is not recoverable, restore the volume from backup.
These tasks are described in Chapter 3, Disk Tasks, Chapter 4, Volume
Tasks, and Chapter 6, Troubleshooting.
