HP Serviceguard Version A.11.18 Release Notes, September 2008

Upgrading from an Earlier Serviceguard Release
• For information about supported Serviceguard upgrade paths, see the support
matrix at docs.hp.com -> High Availability -> Support Matrixes.
• This release of Serviceguard requires HP-UX 11i v2 or 11i v3. For information
about HP-UX upgrade paths, see the HP-UX Installation and Upgrade Guide for the
target version of HP-UX at http://www.docs.hp.com -> <HP-UX target
version>-> Installing and Updating.
• If you are upgrading from a release earlier than A.11.16, see “Access changes as
of A.11.16” (page 52).
Veritas Storage Management Products
Veritas Volume Manager (VxVM) 3.5 is not supported on HP-UX 11i v3. If you are
running VxVM 3.5 as part of HP-UX (VxVM-Base), version 3.5 will be upgraded to
version 4.1 when you upgrade to HP-UX 11i v3. For more information about installing
and updating VxVM, see the Veritas 4.1 Installation Guide at http://www.docs.hp.com
-> 11i v3 -> VxVM.
NOTE: There is a new default Disk Layout Version for VxVM 4.1, and not all earlier
Disk Layout versions are supported on HP-UX 11i v3. See the Veritas 4.1 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 E of the Managing Serviceguard manual.
Requirements for Rolling Upgrade
Rolling upgrade to Serviceguard A.11.18 is supported only if you are upgrading from:
• Serviceguard A.11.15 or greater on HP Integrity systems running HP-UX 11i v2
or 11i v3; or
• Serviceguard A.11.16 or greater on HP 9000 systems running HP-UX 11i v2 or 11i
v3.
Rolling Upgrade Exceptions
HP-UX Cold Install
A rolling upgrade cannot include a cold install of HP-UX on any node. A cold install
will remove configuration information; for example, device file names (DSFs) are not
guaranteed to remain the same after a cold install.
