Changing membership mode

You need not generally change the membership mode because creating a VCS service group automatically changes an instance to vcs mode.

Use the qrmutil --membership-mode option to change the membership mode. The cluster must be shut down. The syntax is:

qrmutil --[-Q | quorum-dev=quorum_device --membership-mode=mode

where:

For example:

qrmutil --quorum-dev=/dev/vx/rdsk/quorum_dg/quorumvol --membership-mode=vcs

To manually configure the Cluster Edition to load VCMP and activate the VCS integration, add membership mode = vcs to the cluster configuration file. After you add this line, the Cluster Edition starts as part of the VCS service group. To configure the Cluster Edition without the Veritas cluster subsystem, enter membership mode = native to the cluster configuration file.

This example sets the membership mode to vcs:

[cluster]
name = isles
max instances = 4
primary protocol = udp
master device = /sybase_cfs/data/master.dat
config file = /sybase_cfg/ASE-15_0/ase.cfg
interfaces path = /sybase_cfg/ASE-15_0/ase.cfg
membership mode = vcs

The Cluster Edition starts in native mode if you do not include vcs or native as the parameter for the membership mode = line, or if you do not include the line.

Changing the membership mode in the cluster configuration file has no affect after you generate the master database. After the master database is generated, use qrmutil to change the membership mode:

qrmutil --quorum-dev= quorum_path --membership-mode=[vcs|native]
