HP Serviceguard for Linux Version A.11.19 Release Notes, April 2009

IMPORTANT: As of Serviceguard A.11.19, this capability requires Quorum Server
Version A.04.00. (It is also provided in a patch to Serviceguard A.11.18 with Quorum
Server Version A.03.00, but Quorum Server Version A.03.00 does not support an alternate
subnet with Serviceguard A.11.19.) See “Quorum Server Upgrade Required if You Are
Using an Alternate Address” (page 12).
Support for HPVM and VMware ESX Server
Serviceguard for Linux supports HP Integrity Virtual Machines (HPVM) version 3.5,
4.0, or 4.1, and VMware ESX Server (VMware) versions 3.5 and 3.0.2.
IMPORTANT: Versions 3.5, 4.0, or 4.1 are the only versions of HPVM that Serviceguard
for Linux A.11.19 supports. See the HP Serviceguard for Linux Certification Matrix at
http://www.hp.com/info/sglx, for the most up-to-date compatibility information.
Serviceguard for Linux A.11.19 supports using an HPVM or VMware ESX server virtual
machine as a cluster node (but not as a package). HPVM is supported on HP Integrity
systems; VMware ESX Server is supported on x86 systems.
For installation and configuration information for each type of virtual machine, see the
documents listed under “For More Information” (page 28).
Points to Note
• HPVM nodes. If any Serviceguard cluster node is an HPVM virtual machine, the
