Configuring a Serviceguard NFS failover package
Configuring a Serviceguard NFS failover package for a CFS environment is similar to configuring
the package for a non-CFS environment. The main difference is that you must configure one
failover package for each server that exports CFS. Use the following procedure to configure a
failover package.
1. Copy the following scripts and make a spearate copy for each package (one package for
each server)
# cd /etc/cmcluster/nfs
# cmmakepkg -p /etc/cmcluster/nfs/nfs1.conf
# cmmakepkg -s /etc/cmcluster/nfs/nfs1.cntl
# cp /opt/cmcluster/nfs/hanfs.sh hanfs.1.sh
# cp /opt/cmcluster/nfs/nfs.mon nfs1.mon
# cp /opt/cmcluster/nfs/nfs.flm nfs1.flm
# cmmakepkg -p /etc/cmcluster/nfs/nfs2.conf
# cmmakepkg -s /etc/cmcluster/nfs/nfs2.cntl
# cp /opt/cmcluster/nfs/hanfs.sh hanfs.2.sh
# cp /opt/cmcluster/nfs/nfs.mon nfs2.mon
# cp /opt/cmcluster/nfs/nfs.flm nfs2.flm
2. Edit the nfs.cntl scripts (nfs1.cntl, nfs2.cntl). Do not modify the FILESYSTEMS section (leave
it commented out), since the file systems are mounted and unmounted by the CFS packages.
Specify the IP address for the package and the subnet to which the IP address belongs.
IP[0]=15.13.114.243
SUBNET[0]=15.13.112.0
This IP address is the relocatable IP address for the package. NFS clients that mount the file
systems in the package will use this IP address to identify the server. You should configure
a name for this address in the DNS, NIS or LDAP database, or in the /etc/hosts file.
3. Set the HA_NFS_SCRIPT_EXTENSION to 1.sh in the nfs1.cntl file
HA_NFS_SCRIPT_EXTENSION = "1.sh"
This will set the NFS specific control script to be run by the package to hanfs.1..sh as we
have named it in the copy command above. Set this to 2.sh in nfs2.cntl.
4. Edit the hanfs.sh scripts (hanfs.1.sh and hanfs.2.sh) as follows
