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

indicating thatthe package is halting abnormally (for example because
of the failure of a service it depends on).
• cmviewcl -v -f line has a new field, last_halt_failed, that shows
whether the last invocation of the halt script of a package on a node succeeded or
failed. The value is no if the halt script ran successfully, or was not run since the
node joined the cluster, or was not run since the package was configured to run
on the node; otherwise it is yes.
• You can use cmmakepkg -l (letter “l”) to see a list of all available modules,
including non-Serviceguard modules such as those supplied in the HP Toolkits.
• You can use cmgetconf -P to write out the configuration information for all
packages in the cluster to a specified location; for example:
mkdir /tmp/pkgconfig
cmgetconf -c clusterA -P /tmp/pkgconfig
Alternate Quorum Server Subnet
Serviceguard 11.19 allows you to configure an alternate subnet for communication
between the cluster nodes and the Quorum Server. You can do this from the command
line or in Serviceguard Manager. For details and instructions, see the HP Serviceguard
Quorum Server Version A.04.00 Release Notes at http://docs.hp.com -> High
Availability -> Quorum Server.
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 13).
Support for HPVM, VMware ESX Server, and Xen Virtual Machines
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); and is also supported on Xen hosts,
where it can manage virtual machines as packages, and can also monitor applications
via cmappmgr (see “About cmappmgr” (page 23)). HPVM is supported on HP Integrity
hosts running HP-UX; VMware ESX Server and Xen are supported on x86 systems.
For installation, configuration, and compatibility information for each type of virtual
machine, see the documents listed under “For More Information” (page 34).
Points to Note about VM Nodes
• HPVM nodes. If any Serviceguard cluster node is an HPVM virtual machine, the
amount of time Serviceguard needs to wait for a failed node’s I/O to complete
