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 both the Quorum Server and Serviceguard, upgrade the
Quorum Server before you upgrade Serviceguard.
CAUTION:
— Special considerations apply to a rolling or non-rolling upgrade to Serviceguard
A.11.19; see “New Cluster Manager” (page 11)
— If you are using an Alternate Quorum Server Subnet (page 37), you must
upgrade the Quorum Server to version A.04.00 before you proceed; see
“Quorum Server Upgrade Required if You Are Using an Alternate Address”
(page 13).
• If you are upgrading from a release earlier than A.11.16, see “Access changes as
of A.11.16” (page 42).
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 when
you upgrade to HP-UX 11i v3. For more information about installing and updating
VxVM, see the appropriate version of the Veritas Installation Guide at http://
www.docs.hp.com -> 11i v3 -> VxVM.
NOTE: There is a new default Disk Layout Version as of 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 D of the Managing Serviceguard manual.
Requirements for Rolling Upgrade
