2.2.3 Reconfiguring quorum

Refer to "Adding and removing a node from CIM" for the GUI procedures.

CLI

The configuration can be changed at any time and is effective immediately. When a new node is added to the quorum set of nodes, the node being added must be part of the cluster so as to guarantee that the new node also has the same quorum configuration. Removing a node from the quorum set can be done without restriction.

When the configuration information is given to the command rcqconfig(1M) as arguments, it performs the transaction to CFREG to update the configuration information. Until CIM is successfully configured and gets the initial state of the quorum, CIM has to respond with the quorum state of False to all queries.

Example

Display the states of all the nodes in the cluster as follows:

fuji2# cftool -n
Node    Number  State   Os      Cpu
fuji2   1       UP      Solaris Sparc
fuji3   2       UP      Solaris Sparc

Display the current quorum configuration as follows:
```
fuji2# rcqconfig -g
```
Nothing is returned, since all nodes have been deleted from the quorum.
Add new nodes in a quorum set of nodes as follows:
```
fuji2# rcqconfig -a fuji2 fuji3
```
Display the current quorum configuration parameters as follows:
```
fuji2# rcqconfig -g
QUORUM_NODE_LIST= fuji2 fuji3
```
Delete nodes from a quorum set of nodes as follows:
```
fuji2# rcqconfig -d fuji2
```
Display the current quorum configuration parameters after one node is deleted as follows:
```
fuji2# rcqconfig -g
QUORUM_NODE_LIST= fuji3
```
Add a new node, fuji10 (which is not in the cluster), in a quorum set of nodes as follows:
```
fuji2# rcqconfig -a fuji2 fuji3 fuji10
Cannot add node fuji10 that is not up.
```
The quorum cannot be set because fuji10 is specified that is excluded from the cluster. The quorum set remains empty.
```
fuji2# rcqconfig -g
```
Nothing is returned, since no quorum configuration has been done.
