On the primary host, deport the snapshot volume’s disk group using the
following command:
# vxdg deport snapvoldg
7
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
8
VxVM will recover the volumes automatically after the disk group import
unless it is set to not recover automatically. Check if the snapshot volume is
initially disabled and not recovered following the split.
If a volume is in the DISABLED state, use the following command on the OHP
host to recover and restart the snapshot volume:
# vxrecover -g snapvoldg -m snapvol ...
9
On the OHP host, back up the snapshot volumes. If you need to remount the
file system in the volume to back it up, first run fsck on the volumes. The
following are sample commands for checking and mounting a file system:
# fsck -F vxfs /dev/vx/rdsk/snapvoldg/snapvol
# mount -F vxfs /dev/vx/dsk/snapvoldg/snapvol
mount_point
Back up the file system using a command such as bpbackup in Symantec
NetBackup. After the backup is complete, use the following command to
unmount the file system.
# umount mount_point
10
On the OHP host, use the following command to deport the snapshot volume’s
disk group:
# vxdg deport snapvoldg
11
On the primary host, re-import the snapshot volume’s disk group using the
following command:
# vxdg [-s] import snapvoldg
Note: Specify the -s option if you are reimporting the disk group to be rejoined
with a shared disk group in a cluster.
