You can set an external managed disk (MDisk) as a quorum disk by using the command-line
interface (CLI).
Note: Quorum functionality is not supported for internal drives on nodes.
To set an MDisk as a quorum disk, use the chquorum
command.
When setting an MDisk as a quorum disk, keep the following recommendations in
mind:
- When possible, distribute the quorum candidate disks so that each MDisk is provided by a
different storage system. For a list of storage systems that support quorum disks, search for
supported hardware list at the following website:
www.ibm.com/support
- Before you set the quorum disk with the chquorum command, use the
lsmdisk or lsdrive command to ensure that the MDisk you want
is online. If you want to set a drive as quorum, use lsdrive to make sure it is
online. If you want to set an MDisk as quorum, use lsmdisk to make sure it is
online.
