For efficient Solaris 11 upgrades on Veritas Cluster do the following
1. Disable Evacuation of the Solaris Zones
-modify myzone_sg Evacuate 0
After the Solaris 11 Upgrade and reboot the Zones are not evacuated to the other Cluster Node.
2. Double check AutoStartList
Check and set the
AutoStartList of your Solaris Zones Service Group to make sure
the Zones are attached to the same Node they are currently running on.
/opt/VRTSvcs/bin/hagrp -modify myzone_sg AutoStartList node1 node2
With this setup you can upgrade your first node, reboot and verify all Zones are running fine.
pkg update --be-name
If all is well with your Solaris Zones and Apps you can do
the same with your second node.
And after all your nodes are upgraded you can enable Evacuation again.
/opt/VRTSvcs/bin/hagrp -modify myzone_sg Evacuate 1
Happy Upgrading ..
