4.11.4 How to Enable or Disable the CCD Quorum

Typically, the cluster software requires a quorum before updating the CCD. The -q option enables you to disable this restriction and to update the CCD with any number of nodes.

Run this option to enable or disable a quorum when updating or restoring the Dynamic CCD. The quorum_flag is a toggle: on (to enable) or off (to disable) a quorum. By default, the quorum is enabled.

For example, if you have three physical nodes, you need at least two nodes to perform updates. Because of a hardware failure, you can bring up only one node. The cluster software does not enable you to update the CCD. If, however, you run the ccdadm -q command, you can toggle off the software control, and update the CCD.

# ccdadm clustername -q on|off
