Serviceguard Extension for RAC Version A.11.19 Release Notes (May 2010)

• As of the date of these release notes, DRD upgrade is supported for clusters that use the LVM or
VxVM volume manager.
IMPORTANT:
See the HP Serviceguard Storage Management Suite A.03.00 Release Notes for information about
DRD upgrades in CVM/CFS environments.
• Use the DRD software released with the September 2009 release of HP-UX 11i v3 or later.
You do not have to upgrade the operating system itself to the September 2009 release, so long
as you are running 11i v3. You can obtain the DRD software free from HP (see “Upgrade Using
DRD” on page 11 above.)
• Serviceguard does not support booting from a clone disk made on another system (sometimes re-
ferred to as DRD re-hosting).
• The cluster must meet both general and release-specific requirements for a rolling or non-rolling
upgrade, as spelled out in this section and in Appendix A of the latest edition of Using Serviceguard
Extension for RAC.
• You must follow the instructions for DRD upgrades under “Performing a Rolling Upgrade Using
DRD” on page 16 or “Performing a Non-Rolling Upgrade Using DRD” on page 18.
IMPORTANT:
If the install depot is on tape (or is a single file) you must copy it onto the clone disk or an upgrade
server before running swinstall or update-ux to upgrade the clone. Do one of the following:
• use swcopy to copy the depot onto the active root disk, then clone the disk, then install the
software from the depot on the clone disk; or
• use swcopy to copy the depot to an external server, then use the depot on the external server
to install the software onto the clone disk
You should also do this if you are going to use update-ux and the install depot is on a CD
mounted on the local system, or is a directory in the active system (for example, in a file system
mounted on the active root disk).
In addition, make sure you do not use control-C to escape from a runcmd drd swinstall
command, as this can cause problems.
