HP Serviceguard Version A.11.20 Release Notes, August 2011
Requirements for Rolling Upgrade to A.11.19
IMPORTANT: Although you can upgrade to Serviceguard A.11.19 while still on HP-UX 11i v2,
you must upgrade to HP-UX 11i v3 in order to upgrade to Serviceguard A.11.20.
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 41), and the Rolling Upgrade Exceptions that follow.
Obtaining a Copy of Serviceguard A.11.19

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.
HP Serviceguard Storage Management Suite and standalone CVM product
In many cases you cannot do a rolling upgrade if you are upgrading the HP Serviceguard Storage
Management Suite.
Specifically you cannot do a rolling upgrade if you are using the Veritas clustering capabilities —
CVM and CFS. In the case of CVM, this applies whether you purchase it as part of a Storage
Management bundle, or as a standalone product.
For more information, see the Veritas 5.0 Installation Guide and the HP Serviceguard Storage
Management Suite A.02.01 Release Notes at http://www.hp.com/go/hpux-serviceguard-docs
—> HP Serviceguard Storage Management Suite.
Migrating to Agile Addressing if Using Cluster Lock Disk
You cannot migrate to the HP-UX 11i v3 agile addressing scheme for device files during a rolling
upgrade if cluster lock disks are used as a tie-breaker, because that involves changing the cluster
configuration. See “Updating the Cluster Lock Configuration” in Chapter 7 of Managing
Serviceguard for instructions in this case. See “About Device Special Files (DSFs)” (page 30) of
these Release Notes for more information about agile addressing.
Upgrading from an Earlier Release if You Are Not Using Rolling Upgrade (Non-Rolling
Upgrade)
If your cluster does not meet the requirements for a rolling upgrade, or you decide not to use rolling
upgrade for some other reason, you must bring down the cluster (cmhaltcl) and then upgrade
Serviceguard and HP-UX on the nodes. See Appendix D of the Managing Serviceguard manual.
