Editing the NFS Monitor Script (nfs.mon)
The NFS monitor script, nfs.mon, contains NFS-specific monitor
variables and functions. The nfs.mon script is an optional component of
HA/NFS. The hanfs.sh file specifies whether the NFS monitor script is
used. The following steps describe how to configure the NFS monitor
script:
1. To monitor the File Lock Migration script (nfs.flm), set the
NFS_FILE_LOCK_MIGRATION variable to 1, and set the
NFS_FLM_SCRIPT name to match the hanfs.sh script value for this
variable:
NFS_FILE_LOCK_MIGRATION=1
NFS_FLM_SCRIPT="${0%/*}nfs1.flm"
NOTE The file name of the NFS_FLM_SCRIPT script must be limited to 14
characters or fewer.
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.
These arguments are passed using the NFS_SERVICE_CMD line in the
hanfs.sh file.
