When you have completed your selections, click Apply at the bottom of the Configure
Matrix window.
Remove membership partitions
Before using this option, verify that Matrix Server is offline on all nodes in the cluster.
When you click Remove, a dialog listing the current membership partitions is
displayed. Select the partition that you want to delete. When you have completed
the dialog, click Apply at the bottom of the Configure Matrix window.
The mx config mp commands
The mx config mp set and repair commands can be used while Matrix Server
is either online or offline; however, only the operations listed under “Online
operations” on page 245 can be performed while Matrix Server is running. For other
operations, Matrix Server must be offline on all nodes in the cluster.
Determine disks/partitions available for membership partitions
To determine the disks that can be used for membership partitions, run this command:
mx config mp list_avail_disks [--noHeaders] [--csv] [--showBorder]
Next, run the following command to see a list of the available partitions on one of
the available disks.
mx config mp list_avail_partitions [--noHeaders] [--csv] [--showBorder]
<disk uuid>
Add membership partitions
Use this command to add new membership partitions:
mx config mp set [--recreate] [--force] [--reuse] <uuid1/partno>
[<uuid2/partno> <uuid3/partno>]
A cluster can have either one or three membership partitions. Specify the UUIDs and
partition numbers for the partitions to be added. If you are adding two membership
partitions, you will need to specify the existing membership partition and the two
partitions that will be added.
The options are:
--recreate
Allow existing membership partition information to be destroyed.
