HP Serviceguard Version A.11.20 Release Notes, August 2011

NOTE: There are files in CM-CORE that are reserved for HP support. Do not change these files.
Do not move, alter, or delete the following:
• /usr/contrib/bin/cmcorefr
• /usr/contrib/bin/cmdumpfr
• /usr/contrib/bin/cmfmtfr
• /usr/contrib/Q4/lib/q4lib/cmfr.pl
• /var/adm/cmcluster/frdump.cmcld.x (where x is a digit)
NOTE: If you did a swremove of an older version of Serviceguard before the swinstall, a
zero-length binary configuration file (/etc/cmcluster/cmclconfig) may be left on your
system. Remove this file before you issue the swinstall command. If you do not remove the
zero-length binary configuration file, the installation will proceed correctly, but you may see error
or warning messages such as:
Bad binary config file directory format.
Could not convert old binary configuration file.
These messages may safely be ignored.
If You Need To Disable identd
CAUTION: HP does not recommend disabling this security feature, as it maintains the integrity
and high availability of your data.
If you must disable identd, do it after installing Serviceguard but before each node rejoins the
cluster (for example, just before issuing the cmrunnode or cmruncl command).
Instructions are in Chapter 5 of the Managing Serviceguard manual, under the heading “Disabling
identd” in the section “Managing the Running Cluster”.
Upgrading from an Earlier Serviceguard Release
You can upgrade to Serviceguard A.11.20 from any earlier release (whether or not that release
is still in support life), but you can perform a rolling upgrade only from A.11.19. Read the bullets
that follow carefully before proceeding.
• This release of Serviceguard requires HP–UX 11i v3. For information about HP-UX upgrade
paths, see the HP-UX Installation and Upgrade Guide at http://www.hp.com/go/
hpux-core-docs —> HP-UX 11i v3.
• In order to do a rolling upgrade to Serviceguard A.11.20, you must be running A.11.19.
If you are running an earlier version, upgrade to A.11.19 before attempting a rolling upgrade
to A.11.20. See “Rolling Upgrade” (page 44).
This restriction does not apply to non-rolling upgrades. For more information about non-rolling
upgrade, see Appendix D of Managing Serviceguard, which you can find at the address
