Sun Cluster 3.0 Data Services Installation and Configuration Guide

Configuring Sun Cluster HA for NFS Extension Properties

You are not required to set any extension properties for Sun Cluster HA for NFS.

See Appendix A, Standard Properties for details of all Sun Cluster properties.

How to Configure Sun Cluster HA for NFS Extension Properties

Typically, you configure extension properties by using the Cluster Module of Sun Management Center or the command line scrgadm -x parameter=value at the time you create the NFS resource. You can also configure them later by using the procedures described in Chapter 9, Administering Data Service Resources.

Table 7-2 describes extension properties you can configure for Sun Cluster HA for NFS. Some extension properties can be updated dynamically, others only when the resource is created. The Tunable column indicates when the property can be updated.

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 the fault monitor is to be restarted by the process monitor facility during the time window specified by the Monitor_retry_interval property. Note that this property refers to restarts of the fault monitor itself, rather than to the resource. Restarts of the resource are controlled by the system defined properties Retry_interval, and Retry_count. See the scrgadm 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 the fault monitor fails is more than the value specified in the extension property Monitor_retry_count within this period, the fault monitor is not restarted by the process monitor facility.

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
