IBM SG24-5131-00 manual Configuring Run-Time Parameters, Defining Application Servers

Service IP Label	If IP address takeover is being used, list the IP label to be
	moved when this resource group is taken over. Press F4
	to see a list of valid IP labels. These include addresses
	which rotate or may be taken over.
File Systems	Identify the method for checking consistency of file
Consistency Check	systems, fsck (default) or logredo (for fast recovery).
File Systems Recovery	Identify the recovery method for the file systems, parallel
Method	(for fast recovery) or sequential (default).
	Do not set this field to parallel if you have shared, nested
	file systems. These must be recovered sequentially. (Note
	that the cluster verification utility, clverify, does not report
	file system and fast recovery inconsistencies.)
File Systems to Export	Identify the file systems to be exported to include in this
	resource group. These should be a subset of the file
	systems listed above. Press F4 for a list.
File Systems to	Identify the subset of file systems to NFS mount. All nodes
NFS Mount	in the resource chain that do not currently hold the
	resource will attempt to NFS mount these file systems
	while the owner node is active in the cluster.

These settings also have to be synchronized throughout the cluster. Therefore Synchronize Cluster Resources has to be chosen from the corresponding SMIT Menu.

If the Cluster Manager is running on the local node, synchronizing cluster resources triggers a dynamic reconfiguration event (DARE, see 8.5.3, “DARE Resource Migration Utility” on page 169).

4.3.1.2 Configuring Run-Time Parameters

There are two types of Run-Time Parameters for a node that can be chosen. One of them is the debug level, which can be switched from high to low, meaning all cluster manager actions are logged, or only errors are logged, respectively. The other is the differentiation whether the node uses NIS or DNS nameservice or not, to enable the cluster manager to turn that off in case it would interfere with its actions. Both of these parameters can be changed while the cluster is running.

4.3.1.3 Defining Application Servers

Application servers are another resource that can be configured into a Resource Group. They consist of a (hopefully meaningful) name, in order to enable the cluster manager to identify the application server uniquely, as well
