Veritas Storage Foundation 5.1 SP1 Advanced Features Administrator"s Guide (5900-1503, April 2011)

# mount -F vxfs -o ckpt=may_23 /dev/vx/dsk/fsvol/vol1:may_23 \
/fsvol_may_23
Note: The vol1 file system must already be mounted before the Storage
Checkpoint can be mounted.
■ To remount the Storage Checkpoint named may_23 as a writable Storage
Checkpoint, type:
# mount -F vxfs -o ckpt=may_23,remount,rw \
/dev/vx/dsk/fsvol/vol1:may_23 /fsvol_may_23
■ To mount this Storage Checkpoint automatically when the system starts up,
put the following entries in the /etc/fstab file:
Device-Special-File Mount-Point fstype options backup- pass-
frequency number
/dev/vx/dsk/fsvol/ /fsvol vxfs defaults 0 0
vol1
/dev/vx/dsk/fsvol/ /fsvol_may_23 vxfs ckpt=may_23 0 0
vol1:may_23
■ To mount a Storage Checkpoint of a cluster file system, you must also use the
-o cluster option:
# mount -F vxfs -o cluster,ckpt=may_23 \
/dev/vx/dsk/fsvol/vol1:may_23 /fsvol_may_23
You can only mount a Storage Checkpoint cluster-wide if the file system that
the Storage Checkpoint belongs to is also mounted cluster-wide. Similarly,
you can only mount a Storage Checkpoint locally if the file system that the
Storage Checkpoint belongs to is mounted locally.
You can unmount Storage Checkpoints using the umount command.
# umount /fsvol_may_23
# umount /dev/vx/dsk/fsvol/vol1:may_23
Note: You do not need to run the fsck utility on Storage Checkpoint pseudo devices
because pseudo devices are part of the actual file system.
