HP Serviceguard Version A.11.20 Release Notes, April 2011

IMPORTANT: See the HP Serviceguard Storage Management Suite A.04.00 Release Notes
and 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, so long as you are running 11i v3.
HP recommends using the latest version of the DRD software, which you can obtain free from
HP (see “Upgrade Using DRD” above.)
• Serviceguard does not support booting from a clone disk made on another system (sometimes
referred to as DRD re-hosting).
• The cluster must meet both general and release-specific requirements for a rolling or non-rolling
upgrade; see the remainder of this section and the sections “Guidelines for Rolling Upgrade”
and “Guidelines for Non-Rolling Upgrade” in Appendix D of the latest edition of Managing
Serviceguard.
• You must follow the instructions for DRD upgrades in Managing Serviceguard; see “Performing
a Rolling Upgrade Using DRD” or “Performing a Non-Rolling Upgrade Using DRD” in Appendix
D of the latest edition of that manual.
IMPORTANT: The following information is additional to the instructions in Appendix D of
Managing Serviceguard.
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.

For information about installing and updating VxVM, see the appropriate version of the Veritas
Installation Guide at http://www.hp.com/go/hpux-core-docs —> 11i v3 — Setup and
install — general.
NOTE: A new default Disk Layout Version was introduced in VxVM 4.1, and not all earlier Disk
Layout versions are supported on HP-UX 11i v3. See the Veritas 5.0 Installation Guide for details.
Rolling Upgrade
In some cases you can upgrade Serviceguard and HP-UX without bringing down the cluster; you
do this by upgrading one node at a time, while that node’s applications are running on an alternate
node. The process is referred to as a rolling upgrade, and is described in Appendix D of the
Managing Serviceguard manual.
