Limitations of Non-Rolling Upgrades using DRD
CAUTION: Stricter limitations apply to an upgrade to A.11.19; do not proceed with
an upgrade to A.11.19 until you have read and understood the “Special Considerations
for Upgrade to Serviceguard A.11.19” in Appendix D of the latest version of Managing
Serviceguard.
IMPORTANT: Not all paths that are supported for upgrade are supported for an
upgrade using DRD, and there are additional requirements and restrictions for paths
that are supported.
Do not proceed until you have read the “Announcements”, “Compatibility”, and
“Installing Serviceguard” sections of the latest version of the Serviceguard release notes
and the corresponding sections of these SGeRAC release notes, made sure your cluster
meets the current requirements, and taken any necessary preparation steps as instructed
in the release notes.
You must also make sure you have read and understood the “Restrictions for DRD
Upgrades” (page 17).
In addition, all the limitations for non-rolling upgrades listed in Appendix A of Using
Serviceguard Extension for RAC also apply to non-rolling upgrades using DRD. You
should also read the section on “Non-Rolling Software Upgrades” in that Appendix
before you proceed.
Steps for a Non-Rolling Upgrade Using DRD
Use the following steps for a non-rolling software upgrade using DRD:
1. Create a clone root disk for each node.
2. Upgrade each clone disk to the new HP-UX release (if necessary), including
Serviceguard (using drd runcmd update-ux), or upgrade Serviceguard alone
(using drd runcmd swinstall).
3. Upgrade each clone disk to the new release of SGeRAC
4. Halt Oracle (RAC, CRS, Clusterware, OPS) on all nodes in the cluster.
5. Halt all nodes in the cluster:
