Serviceguard NFS Toolkit A.11.31.02, A.11.11.06, and A.11.23.05 Administrator's Guide

NOTE: The file name of theNFS_FLM_SCRIPT script must be limited to 13
characters or fewer.
NOTE: The nfs.mon script uses rpcinfo calls to check the status of various
processes. If the rpcbind process is not running, the rpcinfo calls time out after 75
seconds. Because 10 rpcinfo calls are attempted before failover, it takes
approximately 12 minutes to detect the failure. This problem has been fixed in
release version 11.11.04 and 11.23.03.
2. You can call the nfs.mon script with the following optional arguments:
• Interval - the time (in seconds) between the attempts for checking if NFS
processes are up and running. The default is 10 seconds.
• Lockd Retry - the number of attempts to ping rpc.lockd before exiting. The
default is 4 attempts.
• Retry - the number of attempts to ping the rpc.statd, rpc.mountd, nfsd,
rpc.pcnfsd, and nfs.flm processes before exiting. The default is 4 attempts.
• Portmap Retry - the number of attempts to ping the rpcbindprocess before
exiting. The default is 4 attempts.
These arguments are passed using the NFS_SERVICE_CMD line in the hanfs.sh
file. In order to set these optional arguments, all of the preceding arguments must
also be specified in the NFS_SERVICE_CMD line.
Editing the Package Configuration File (nfs.conf)
1. Serviceguard A.11.17 provides a new package configuration file template. The
new package configuration file template introduces the following dependency
variables:
• DEPENDENCY_NAME
• DEPENDENCY_CONDITION
• DEPENDENCY_LOCATION
The above parameters are not supported in Serviceguard NFS Toolkit A.11.23.05.
By default, these variables are commented out in the nfs.conf file.
2. Set the PACKAGE_NAME variable.
PACKAGE_NAME pkg01
You can use the default package name if you will run only one Serviceguard NFS
package on your Serviceguard cluster. Each package must have a unique name.
3. Create a NODE_NAME variable for each node that will run the package. The first
NODE_NAME should specify the primary node. All the NODE_NAME variables
following the primary node should specify the adoptive nodes, in the order in
which they will be tried.
