Serviceguard NFS Toolkit A.11.11.06, A.11.23.05 and A.11.31.05 Administrator's Guide

NOTE: The file name of the NFS_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.
• STATD_RETRY, MOUNTD_RETRY, NFSD_RETRY, PCNFSD_RETRY and
NFS_FLM_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 rpcbind process 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.
NODE_NAME thyme NODE_NAME basil NODE_NAME sage
4. Set the RUN_SCRIPT and HALT_SCRIPT variables to the full path name of the control script
(/etc/cmcluster/nfs/nfs.cntl or whatever you have renamed it). You do not have
to specify a timeout for either script.
RUN_SCRIPT /etc/cmcluster/nfs/nfs1.cntl
RUN_SCRIPT_TIMEOUT NO_TIMEOUT
HALT_SCRIPT /etc/cmcluster/nfs/nfs1.cntl
HALT_SCRIPT_TIMEOUT NO_TIMEOUT
5. If you want to run the NFS monitor script, set the SERVICE_NAME variable to indicate the
NFS monitor script:
SERVICE_NAME nfs1.monitor
