Serviceguard NFS Toolkit A.11.11.06, A.11.23.05 and A.11.31.03 Administrator's Guide

4. Edit the hanfs.sh scripts (hanfs.1.sh and hanfs.2.sh). if you want to monitor NFS services
(by running the NFS monitor script). To monitor NFS services, set the NFS_SERVICE_NAME
and NFS_SERVICE_CMD variables
NFS_SERVICE_NAME[0]=nfs1.monitor
NFS_SERVICE_CMD[0]=/etc/cmcluster/nfs/nfs1.mon
In hanfs.2.sh, set NFS_SERVICE_NAME[0] to nfs2.monitor and set NFS_SERVICE_CMD[0]
to /etc/cmcluster/nfs/nfs2.mon. If you do not want to monitor NFS services, leave these
variables commented out.
5. Edit the nfs.conf scripts (nfs1.conf and nfs2.conf) as follows
a. Specify the package name
PACKAGE_NAME SG-NFS1
b. In nfs2.conf set the PACKAGE_NAME to SG-NFS2
c. The PACKAGE_TYPE should be set to the default value (FAILOVER)
d. Set the NODE_NAME variables for each node that can run the package. The first
NODE_NAME should specify the primary node, followed by adoptive node(s) in the
order in which they will be tried
NODE_NAME thyme
NODE_NAME basil
e. Set the RUN_SCRIPT and HALT_SCRIPT variables to the full path of the control script,
with no timeout
RUN_SCRIPT /etc/cmcluster/nfs/nfs1.cntl
RUN_SCRIPT_TIMEOUT NO_TIMEOUT
HALT_SCRIPT /etc/cmcluster/nfs/nfs1.cntl
HALT_SCRIPT_TIMEOUT NO_TIMEOUT
Similarly, set the RUN_SCRIPT and HALT_SCRIPT variables to
/etc/cmcluster/nfs/nfs2.cntl in nfs2.conf
f. Set the DEPENDENCY_NAME, DEPENDENCY_CONDITION, and
DEPENDENCY_LOCATION variables so that the failover package will only run if the
export package is already running
DEPENDENCY_NAME SG-CFS-XP-1-dep
DEPENDENCY_CONDITION SG-CFS-XP-1=UP
DEPENDENCY_LOCATION SAME_NODE
g. To monitor NFS services, set the SERVICE_NAME variable
SERVICE_NAME nfs1.monitor
h. In nfs2.conf, set SERVICE_NAME to nfs2.monitor. The SERVICE_NAME variable in
the nfs.conf scripts must match the NFS_SERVICE_NAME[0] variable in the
hanfs.sh.script. If you do not want to monitor NFS services, leave this variable
commented out.
i. Set the SUBNET variable in both nfs1.conf and nfs2.conf
SUBNET 15.13.112.0
Starting a Serviceguard NFS failover package
Use the following procedure to start a failover package.
1. Copy the configuration files to each server in the cluster
# rcp -p /etc/cmcluster/nfs/* (hostname) :/etc/cmcluster/nfs
2. Verify the cluster and package configuration files on each server
# cmcheckconf -k -v -C /etc/cmcluster/cluster.conf -P /etc/cmcluster/nfs/nfs1.conf
-P /etc/cmcluster/nfs/nfs2.conf -P /etc/cmcluster/nfs/nfs2.conf
