HP Serviceguard Version A.11.20 Release Notes, February 2014

Quorum Server Upgrade Required if You Are Using an Alternate Address
If you are using an alternate address on a Serviceguard version earlier than A.11.19, you must
upgrade the Quorum Server to version A.04.00 before you upgrade the cluster. See About the
Alternate Quorum Server Subnet (page 31) for more information.
CAUTION: If you fail to do this, the upgraded cluster will be running without a cluster lock until
you have upgraded the Quorum Server.
Serviceguard Manager Available from the System Management Homepage (SMH)
For details, see “Serviceguard Manager” (page 25).
NOTE: The earlier, station-management version of Serviceguard Manager is obsolete (as of
Serviceguard A.11.18). The last version of Serviceguard that supports that product is A.11.17
(A.11.17.01 on HP-UX 11i v3).
Support for Mixed-OS Clusters (HP–UX 11i v2 and 11i v3)
With some limitations, HP now supports Serviceguard clusters in which some nodes are running
HP-UX 11i v2 and some 11i v3. You may want to take advantage of this if you are currently running
Serviceguard A.11.19 on HP-UX 11i v2 and want to upgrade the nodes to 11i v3 over a period
of time, in preparation for upgrading to Serviceguard A.11.20.
IMPORTANT: The cluster must be running Serviceguard A.11.19. Serviceguard A.11.20 does
not run on HP–UX 11i v2.
For more information, see “Mixed Clusters” (page 36).
Support for Veritas Products from Symantec
For the most up-to-date information, check the HP Serviceguard/SGeRAC/Serviceguard Storage
Management Suite/Serviceguard Manager Plug-in Compatibility and Feature Matrix, at the address
given under “Compatibility Information and Installation Requirements” (page 36).
Version 4.3 of HPVM or HP-UX vPars and Integrity Virtual Machines 6.1Required
HP Integrity Virtual Machines (HPVM) 4.3 and HP-UX vPars and Integrity Virtual Machines 6.1 are
supported with Serviceguard A.11.20 March 2012 patch and later. See “Support for HP Integrity
Virtual Machines (HPVM)” (page 33) for more information about HPVM. See also “About
cmappmgr” (page 31).
ipnodes Entries Needed in /etc/nsswitch.conf
Beginning with version A.11.19, Serviceguard uses calls that require ipnodes entries to be
configured in the /etc/nsswitch.conf. See “Safeguarding against Loss of Name Resolution
Services” in Chapter 5 of Managing Serviceguard for more information.
Legacy Packages
As of Serviceguard A.11.20, new package features are being implemented only in modular
packages (those created using the method introduced in A.11.18).
IMPORTANT: Support for legacy packages (created using the earlier method) will be withdrawn
altogether in a future release. Use the modular method to create new packages whenever possible.
See Chapter 6 of Managing Serviceguard for more information.
