Validating VxVM Disk Groups for Use with
MetroCluster/SRDF
The following section shows how to validate VERITAS diskgroups. On
one node do the following:
1. Deport the disk group.
# vxdg deport logdata
2. Enable other cluster nodes to have access to the disk group.
# vxdctl enable
3. Split the SRDF link to enable R2 Read/Write permission.
# symrdf -g dgoraA split
# symrdf -g dgoraB split
4. Import the disk group.
# vxdg -tfC import logdata
5. Start the logical volume in the disk group.
# vxvol -g logdata startall
6. Create a directory to mount the volume.
# mkdir /logs
7. Mount the volume
# mount /dev/vx/dsk/logdata/logfile /logs
8. Check to make sure the file system is present, then unmount the file
system.
# umount /logs
9. Establish the SRDF link:
# symrdf -g devgrpA establish
