The DB2® cluster
services tiebreaker
is set up initially in the installation GUI when the first instance
is created. Change the cluster manager quorum type only if a problem
occurs with the specified disk or the configuration changes.
Before you begin
- The DB2 pureScale® instance
must be stopped on all hosts before the quorum type can be changed.
The cluster manager must remain online.
- If you are changing to a disk tiebreaker, you can specify the
disk in a device path format or as a PVID or WWN number. The disk
you specify cannot be used for any other purpose.
- The disk option for the cluster manager can be entered in the
form of a device path (for example: /dev/hdisk0), or as a PVID (port
virtual local area network identifier) or WWN (world wide name) number.
- To perform this task, you must be the DB2 cluster
services administrator.
