Rename Veitas Shared Disk Group

How do you rename a shared disk group cfs_group_name configured under SFCFSHA ?

Assumptions:

- cfs_group_name is VCS cluster group importing DG on multiple nodes at same time.
- Shred filesystem is mounted on all cluster nodes in read-write mode

• Bring cfs_group_name offline on all nodes. Repeat below for each node

         hagrp -offline cfs_group_name -sys node1

• Confirm cfs_group_name is offline on all nodes

          hastatus -sum

• Fine out which node is master node

         vxdctl -c mode

• From master node, deport DG on one node. It will deport on on all other node

        vxdg deport old_dg_name

•     Import DG on master node with new name

    vxdg -n app_data_dg -s import old_dg_name ## -s == shared

• Update Veritas config file

           haconf -makerw
     hares -modify cvmvoldg1 CVMDiskGroup app_data_dg
     hares -modify cfsmount1 BlockDevice /dev/vx/dsk/app_data_dg/appvol
     haconf -dump -makero  ## it will update config on all nodes

• Bring cfs_group_name online on all nodes (repeat below on each node)

          hagrp -online cfs_group_name -sys node1

• Verify shared filesystem has been monted sucessfully and there is no error in log

           df -hP ; tailf /var/VRTSvcs/log/engine_A.log
