Serviceguard Extension for RAC Version A.11.20 Release Notes, April 2013

If, after reading and understanding the restrictions, you decide to perform a rolling upgrade using
DRD, follow the instructions under “Performing a Rolling Upgrade Using DRD” (page 20).
Non-Rolling Upgrade Using DRD
In a non-rolling upgrade with DRD, you clone each node's root disk and apply the upgrade to the
clone, halt the cluster, and then reboot each node from its updated clone root disk.
This method involves much less cluster down time than a conventional non-rolling upgrade, and is
particularly safe because the nodes can be quickly rolled back to their original (pre-upgrade) root
disks. But you must make sure your cluster is eligible. See “Restrictions for DRD Upgrades” (page
17).
If, after reading and understanding the restrictions, you decide to perform a non-rolling upgrade
using DRD, follow the instructions under “Performing a Non-Rolling Upgrade Using DRD” (page
21).
