Sun Cluster 3.0 U1 Data Services Installation and Configuration Guide

Configuring Sun Cluster HA for NFS Extension Properties

Typically, you use the command line scrgadm -x parameter=value to configure extension properties when you create the NFS resource. You can also use the procedures in Chapter 11, Administering Data-Service Resources to configure them later. You are not required to set any extension properties for the Sun Cluster HA for NFS data service. See Appendix A, Standard Properties for details of all Sun Cluster properties.

Table 7-2 describes extension properties that you can configure for the Sun Cluster HA for NFS data service. You can update some properties dynamically. You can update others, however, only when you create the resource. The Tunable column indicates when you can update the property.

Table 7-2 Sun Cluster HA for NFS Extension Properties


Name/Data Type	Default	Range	Tunable	Description
`Lockd_nullrpc_timeout` (integer)	`120`	Minimum = `60`	Any time	The time-out value (in seconds) to use when probing `lockd`.
`Monitor_retry_count` (integer)	`4`	`0` - `2,147,483,641` `-1` indicates an infinite number of restart attempts.	Any time	The number of times that the process monitor facility (PMF) restarts the fault monitor during the time window that the `Monitor_retry_interval` property specifies. Note that this property refers to restarts of the fault monitor itself, rather than the resource. The system-defined properties `Retry_interval` and `Retry_count` control restarts of the resource. See the `scrgadm`(1M) man page for a description of these properties.
`Monitor_retry_interval` (integer)	`2`	`0` - `2,147,483,641` `-1` indicates an infinite amount of time.	Any time	The time (in minutes) over which failures of the fault monitor are counted. If the number of times that the fault monitor fails is more than the value that is specified in the extension property `Monitor_retry_count` within this period, the PMF restarts the fault monitor.
`Mountd_nullrpc_restart` (Boolean)	`True`	None	Any time	A Boolean to indicate whether to restart `mountd` when a null `rpc` call fails.
`Mountd_nullrpc_timeout` (integer)	`120`	Minimum = `60`	Any time	The time-out value (in seconds) to use when probing `mountd`.
`Nfsd_nullrpc_restart` (Boolean)	`True`	None	Any time	A Boolean to indicate whether to restart `nfsd` when a null `rpc` call fails.
`Nfsd_nullrpc_timeout` (integer)	`120`	Minimum = `60`	Any time	The time-out value (in seconds) to use when probing `nfsd`.
`Rpcbind_nullrpc_reboot` (Boolean)	`True`	None	Any time	A Boolean to indicate whether to reboot the system when a null `rpc` call on `rpcbind` fails.
`Rpcbind_nullrpc_timeout` (integer)	`120`	Minimum = `60`	Any time	The time-out value (in seconds) to use when probing `rpcbind`.
`Statd_nullrpc_timeout` (integer)	`120`	Minimum = `60`	Any time	The time-out value (in seconds) to use when probing `statd`.
