HP Serviceguard Version A.11.17 Release Notes, March 2006 (revised)

Serviceguard Version A.11.17 Release Notes
Installing Serviceguard on HP-UX 11i v2
Chapter 1 27
3. The swremove command should be issued from one system at a time.
That is, if Serviceguard is being de-installed from more than one
system, it should be removed from one system at a time.
If your system is left with a zero-length binary configuration file
(/etc/cmcluster/cmclconfig), you should remove it.
4. Before doing an swremove of both the Serviceguard and the Event
Monitoring Service (EMS) products, make sure that all user-written
resource monitors are terminated.
NOTE When you remove Serviceguard from a system, the Event Monitoring
Service (EMS) is not automatically removed. If you intend to
re-install Serviceguard at a later time, or if you are installing a
different version of Serviceguard, you should check if this version of
Serviceguard requires a newer version of EMS, and if so, remove the
existing EMS version separately before re-installing Serviceguard.
If You Are Upgrading from Earlier Releases
Rolling upgrade to A.11.17 for HP-UX 11iv 2 is supported only if
upgrading from Serviceguard A.11.15 or greater for IPF on HP-UX 11i v
1.6 or 11i v2, and for A.11.16 or greater on PA.
A rolling upgrade is not supported if you are currently using VERITAS
CVM or CFS; these require a fresh install.
NOTE A cold install of the operating system during a rolling upgrade is not
supported. This is because the Serviceguard conversion tools cannot be
guaranteed to match the same network PPA numbers that were in use
before the upgrade. Also, disk device file names can be changed by a cold
install, causing mismatches between the Serviceguard configuration and
the system configuration.
