HP Serviceguard Version A.11.19 Release Notes, March 2009

Quorum Server Upgrade Required if You Are Using an Alternate Address
If you are using an Alternate Quorum Server Subnet (page 37), you must upgrade the
Quorum Server to version A.04.00 before you upgrade the cluster to Serviceguard
A.11.19.
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 “About Serviceguard Manager” (page 26).
NOTE: The earlier, station-management version of Serviceguard Manager is obsolete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. See “Mixed Clusters” (page 45).
Version 3.5, 4.0, or 4.1 of HPVM Required
If you intend to use HP Integrity Virtual Machines (HPVM) with Serviceguard A.11.19,
you must install or upgrade to HPVM 3.5, 4.0, or 4.1; these are the only versions
currently supported with Serviceguard A.11.19. See “Support for HP Integrity Virtual
Machines (HPVM)” (page 41) for more information about HPVM.
Legacy Packages
In A.11.19, you can still create new packages using the legacy method (the method
used before Serviceguard A.11.18; see “Configuring a Legacy Package” in Chapter 7
of Managing Serviceguard). In some cases new capabilities provided in modular packages
(those created by the method introduced in A.11.18) have been added to legacy packages
as well. But after A.11.19, new features will be implemented only in modular packages.
IMPORTANT: Support for legacy packages will be withdrawn altogether in a future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.
.rhosts Deprecated
Using the .rhosts file as a means of allowing root access to an unconfigured node is
deprecated as of Serviceguard A.11.19; support for this method will be withdrawn in
a future release. You should use $SGCONF/cmclnodelist instead. See “Allowing
