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:
vcs – indicates the Cluster Edition is running with the VCS cluster subsystem
native – indicates the Cluster Edition is running without the VCS cluster subsystem
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]
