Overview of Serviceguard NFS with
Serviceguard A.11.17 Support
Serviceguard NFS Toolkit A.11.23.05 can work with Serviceguard
A.11.17. Serviceguard A.11.17 supports Veritas Cluster File System
(CFS) which allows a file system to be created that can be mounted by all
nodes in a cluster environment. The detailed information of using
Serviceguard NFS Toolkit A.11.23.05 with Serviceguard A.11.17 is as
follows:
• Serviceguard NFS Toolkit A.11.23.05 does not support sharing of
CFS file systems. Serviceguard NFS Toolkit will support it in a
future release.
• Serviceguard NFS Toolkit A.11.23.05 supports the new variable
HA_NFS_SCRIPT_EXTENSION in the control script (nfs.cntl). This
new variable can be used to modify the name of the NFS specific
control shell script (hanfs.sh) that is associated with a package.
For example, if you set the HA_NFS_SCRIPT_EXTENSION variable to
hapkg or hapkg.sh, then the NFS specific control script executed by
the package corresponding to this nfs.cntl file will be
hanfs.hapkg.sh. The default shell script name for this variable is
hanfs.sh.
• Serviceguard with Veritas CFS feature integration provides the
capability of creating a file system that can be mounted by all nodes
in a cluster. The Serviceguard CFS feature provides performance
improvement and cache coherency.
HP recommends that you use the Serviceguard CFS feature instead
of setting up server-to-server cross-mounting configuration. To use
Serviceguard with the Veritas CFS feature, you need to install
Serviceguard version A.11.17. For more information, refer to
Managing Serviceguard, 12th Edition at the following web site:
http://docs.hp.com/en/ha.html#Serviceguard
Serviceguard A.11.17 is not available on HP-UX 11i v1 systems, so
Serviceguard CFS support is only applicable to HP-UX 11i v2.
