Sample configuration file for removing a node from the cluster


Sample configuration file for removing a node from the cluster
Prev	Removing a node from SFCFSHA clusters	Next

You may use this sample file as reference information to understand the configuration changes involved when you remove a node from a cluster.

The existing sample configuration before removing the node sys3 is as follows:

The existing clusterclus1comprises three nodes sys1, sys2, and sys3 and hosts a single database.
The database is stored on CFS.
The database is managed by a VCS database agent.

The agent starts, stops, and monitors the database.

Note:

The following sample file shows in bold the configuration information that is removed when the node sys3 is removed from the cluster.

include "types.cf"
include "CFSTypes.cf"
include "CVMTypes.cf"

cluster clus1 (
        UserNames = { admin = bopHo }
        Administrators = { admin }
        UseFence = SCSI3
        )

cluster clus1 (
        UserNames = { admin = bopHo }
        Administrators = { admin }
        UseFence = SCSI3
        )

system sys1 (
        )
system sys2 (
        )
system sys3 (
       )

Note:

In the following group app_grp, the sys3 node must be removed.

group app_grp (
        SystemList = { sys1 = 0, sys2 = 1, sys3 = 2 }
        AutoFailOver = 0
        Parallel = 1
        AutoStartList = { sys1, sys2, sys3 }
        )

Note:

In the following application resource, the sys3 node information must be removed.

App app1 (
										Critical = 0
										Sid @sys1 = vrts1							
								  Sid @sys2 = vrts2
          Sid @sys3 = vrts3
          )

Note:

In the following CVM and CVMCluster resources, the sys3 node information must be removed.
