On the master node, use the following command to wait for the contents of
the snapshot to be fully synchronous with the contents of the original volume:
# vxsnap -g volumedg syncwait snapvol
For example, to wait for synchronization to finish for the snapshots scfs_vol:
# vxsnap -g exampledg syncwait scfs_vol
Note: You cannot move a snapshot volume into a different disk group until
synchronization of its contents is complete. You can use the vxsnap print
command to check on the progress of synchronization.
4
On the master node, use the following command to split the snapshot volume
into a separate disk group, snapvoldg, from the original disk group, volumedg:
# vxdg split volumedg snapvoldg snapvol
For example, to place the snapshot of the volume cfs_vol into the shared
disk group splitdg:
# vxdg split exampledg splitdg scfs_vol
5
On the master node, deport the snapshot volume’s disk group using the
following command:
# vxdg deport snapvoldg
For example, to deport the disk group splitdg:
# vxdg deport splitdg
6
On the OHP host where the backup is to be performed, use the following
command to import the snapshot volume’s disk group:
# vxdg import snapvoldg
For example, to import the disk group splitdg:
# vxdg import splitdg
7
The snapshot volume is initially disabled following the split. Use the following
command on the OHP host to recover and restart the snapshot volume:
# vxrecover -g snapvoldg -m snapvol
