To complete the phased upgrade

1. Verify that the cluster UUID on the nodes in the second subcluster is the same as the cluster UUID on the nodes in the first subcluster. Run the following command to display the cluster UUID:

   # /opt/VRTSvcs/bin/uuidconfig.pl [-rsh] -clus -display nodename

   If the cluster UUID differs, manually copy the cluster UUID from a node in the first subcluster to the nodes in the second subcluster. For example:

   # /opt/VRTSvcs/bin/uuidconfig.pl [-rsh] -clus -copy -from_sys \
   node01 -to_sys node03 node04

2. Restart the upgraded nodes in the second half of the cluster:

   # /usr/sbin/shutdown -i6 -g0 -y

   When second half of the nodes come up, all the GAB ports a, b, d, h, u, v, w and f are ONLINE. Also all the CFS mounts service groups come online automatically.

3. For nodes that use Solaris 10, start VCS in first half of the cluster:

   # svcadm enable system/vcs

4. Manually mount the VxFS and CFS file systems that are not managed by VCS in the second half of the cluster.
5. Find out which node is the CVM master. Enter the following:

   # vxdctl -c mode 

6. On the CVM master node, upgrade the CVM protocol. Enter the following:

   # vxdctl upgrade
