Installing and Conﬁguring Serviceguard NFS

Conﬁguring a Serviceguard NFS Package

Chapter 238

4. Specify the IP address for the package and the address of the subnet

to which the IP address belongs.

IP[0]=15.13.114.243

SUBNET[0]=15.13.112.0

The IP address you specify 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 or NIS database, or in the

/etc/hosts ﬁle.

5. If you want to run the NFS monitor script , set the

NFS_SERVICE_NAME variable to the value of the SERVICE_NAME

variable in the package conﬁguration ﬁle. Each package must have a

unique service name.

NFS_SERVICE_NAME[0]=nfs1.monitor

If you do not want to run the NFS monitor script, comment out the

NFS_SERVICE_NAME and NFS_SERVICE_CMD variables:

# NFS_SERVICE_NAME[0]=nfs.monitor

# NFS_SERVICE_CMD[0]=/etc/cmcluster/nfs/nfs.mon

By default, the NFS_SERVICE_NAME and NFS_SERVICE_CMD variables

are commented out, and the NFS monitor script is not run.

You do not have to run the NFS monitor script. If your NFS package

conﬁguration ﬁle speciﬁes PKG_SWITCHING_ENABLED YES and

NET_SWITCHING_ENABLED YES (the defaults), the package will switch

to the next adoptive node or to a standby network interface in the

event of a node or network failure. The NFS monitor script causes

the package failover if any of the monitored NFS services fails.

6. If you run the NFS monitor script, set the NFS_SERVICE_CMD

variable to the full path name of the NFS monitor script.

NFS_SERVICE_CMD[0]=/etc/cmcluster/nfs/nfs.mon

The path name for the executable script does not have to be unique to

each package. Every package can use the same script. Multiple

instances of the monitor script can run on the same node without any

problems, and if a package fails over, only the instance associated

with that package is killed.

If you do not want to run the NFS monitor script, comment out the

NFS_SERVICE_NAME and NFS_SERVICE_CMD variables:
