Shutting down VCS (phased only)

Shutdown VCS on remaining nodes that are not being upgraded to preventing them from rejoining the cluster.

 To shut down the cluster

1. Stop VCS on each of the second group of nodes:

   # hastop -local

2. Reboot the upgraded nodes. Assuming the reboot was successful, application failover is now available for the first group of nodes.
3. If any VCS configuration files need to be restored, stop the cluster, restore the files to the /etc/VRTSvcs/conf/config directory, and restart the cluster.
4. Make the VCS configuration writable again from any node in the upgraded group:

   # haconf -makerw

5. Enter the following command on each node in the upgraded group to unfreeze HA service group operations:

   # hasys -unfreeze -persistent node_name

6. Make the configuration read-only:

   # haconf -dump -makero

7. Bring the CVM service group online on each node in the upgraded group:

   # hagrp -online cvm -sys node_name

8. Proceed to Confirm startup (phased or full).
