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

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

VxVM will recover the volumes automatically after the disk group import

unless it is set not to 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

For example, to start the volume snapvol:

# vxrecover -g splitdg -m snapvol

On the OHP host, use the following commands to check and locally mount

the snapshot volume:

# fsck -F vxfs /dev/vx/rdsk/diskgroup/volume

# mount -F vxfs /dev/vx/dsk/diskgroup/volume

mount_point

For example, to check and mount the volume scfs_vol in the disk group splitdg

for shared access on the mount point, /bak/mnt_pnt:

# fsck -F vxfs /dev/vx/rdsk/splitdg/scfs_vol

# mount -F vxfs /dev/vx/dsk/splitdg/scfs_vol /bak/mnt_pnt
