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 every server that exports CFS.

1. Copy the following scripts and make a separate copy for each package. You

must create 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

# 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

2. Edit the nfs.cntl scripts (nfs1.cntl, nfs2.cntl). 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 must configure a name for this IP 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) 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
