Configuring a Serviceguard NFS Legacy Package
To configure a Serviceguard NFS legacy package, complete the following tasks, included in this
section:
• “Copying the Template Files”
• “Editing the Control Script (nfs.cntl)”
• “Editing the NFS Control Script (hanfs.sh) ”
• “Editing the File Lock Migration Script (nfs.flm)”
• “Editing the NFS Monitor Script (nfs.mon)”
• “Editing the Package Configuration File (nfs.conf)”
• “Configuring Server-to-Server Cross-Mounts (Optional)”
• “Creating the Cluster Configuration File and Bringing Up the Cluster”
Copying the Template Files
If you will run only one Serviceguard NFS package in your Serviceguard cluster, you do not
have to copy the template files. However, if you will run multiple Serviceguard NFS packages,
each package must have its own package configuration file and control script.
NOTE: Serviceguard NFS Toolkit requires Serviceguard A.11.13 (or above). To enable the File
Lock Migration feature (available with 11i v1 and 11i v2), you need Serviceguard A.11.15 or
above.
To ensure that the File Lock Migration feature functions properly, install HP-UX 11i v1 NFS
General Release and Performance Patch, PHNE_26388 (or a superseding patch). For HP-UX 11i
v2, the feature functions properly without a patch.
There is an additional NFS specific control script, hanfs.sh, which is delivered along with the
Serviceguard NFS Toolkit product. All of the NFS specific functions and variables have been
extracted from the original Serviceguard package control script to this control script. You must
configure this control script, too.
For each Serviceguard NFS package, create a copy of the following scripts with a unique name.
For example:
cd /etc/cmcluster/nfs
cp nfs.conf nfs1.conf
cp nfs.conf nfs2.conf
cp nfs.cntl nfs1.cntl
cp nfs.cntl nfs2.cntl
cp hanfs.sh hanfs1.sh
cp hanfs.sh hanfs2.sh
cp nfs.flm nfs1.flm
cp nfs.flm nfs2.flm
NOTE: The nfs.flm script is available on 11i v1 and 11i v2.
Editing the Control Script (nfs.cntl)
The control script, nfs.cntl, is different as of the A.11.11.02 and A.11.00.05 releases. For
Serviceguard NFS Toolkit A.11.00.04 or lower for HP-UX 11.0 or Serviceguard NFS Toolkit
A.11.11.01 or lower for HP-UX 11i v1 using Serviceguard A.11.09 (or below) framework, see
“Editing nfs.cntl for NFS Toolkit A.11.00.04 and A.11.11.01 (or lower)” (page 30) to edit the
control script, nfs.cntl.
