HP Serviceguard Version A.11.20 Release Notes, April 2011

Requirements for Rolling Upgrade to A.11.20
To perform a rolling upgrade to Serviceguard A.11.20, you must be running:
• HP-UX 11i v3 and
• Serviceguard A.11.19
If you are not already running A.11.19, you may be able to do a rolling upgrade to A.11.19,
and from A.11.19 to A.11.20. See the next two subsections.
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 43), 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.
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
