For information about installing and updating VxVM, see the appropriate version of
the Veritas Installation Guide on docs.hp.com, for example, http://
www.docs.hp.com -> 11i v3 -> VxVM.
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.
Requirements for Rolling Upgrade
Rolling upgrade to Serviceguard A.11.19 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.
IMPORTANT: If you are upgrading from A.11.16 on HP-UX 11i v2 , you must
first install patch PHSS_31072 or a later patch.
See also the requirements listed above under “Upgrading from an Earlier Serviceguard
Release” (page 59), and the Rolling Upgrade Exceptions that follow.
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.
