HP Serviceguard Version A.11.18 Release Notes, September 2008

Serviceguard now supports cell OL* (online addition and deletion of cells) on HP
Integrity servers that support them).
For more information about using Serviceguard with partitioned systems, see the
white paper HP Serviceguard Cluster Configuration for HP-UX 11i or Linux Partitioned
Systems at http://docs.hp.com -> High Availability ->
Serviceguard ->White Papers.
You can now use the FSWeb utility to configure LVM volumes in a Serviceguard
cluster (and SLVM volumes if the add-on product Serviceguard Extension for Real
Application Cluster (SGeRAC) is installed).
For more information about FSWeb, see the fsweb (1m) manpage.
With the patch listed under “New Features for September 2008 Patch” (page 20),
Serviceguard supports the increased number of LVM volume groups supported
by the HP-UX 11i v3 0809 Fusion release; the maximum number of volume groups
you can configure in a Serviceguard cluster is the maximum supported by HP-UX.
See the HP-UX documentation for details.
Serviceguard A.11.18, with the patch listed under “New Features for September
2008 Patch” (page 20), supports LVM 2.0 volume groups, both for data and the
cluster lock. See About LVM 2.0” (page 47).
Changes First Introduced in Earlier Releases
The following important changes have either been introduced since the previous edition
of the Serviceguard Release Notes was published, or may affect the upgrade from an
earlier release.
As of A.11.16, Serviceguard supports HP Integrity Virtual Machines (HPVM).
IMPORTANT: Serviceguard A.11.18 supports only version 3.0 or 3.5 of HPVM.
See the Serviceguard/SGeRAC/SMS/Serviceguard Mgr Plug-in Compatibility and Feature
Matrix, on docs.hp.com -> High Availability, under the heading
Serviceguard -> Support Matrixes, for the most up-to-date compatibility
information.
Serviceguard A.11.18 supports an HPVM either as a package or as a cluster node.
If any Serviceguard cluster node is a virtual machine, the amount of time
Serviceguard needs to wait for a failed node’s I/O to complete increases.
See About HPVM and Cluster Re-formation Time” (page 48).
As of A.11.16, Serviceguard uses Access Control Policies to control access to, and
administrative control over, the cluster.
