Setting a quorum disk using the CLI

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 SAN Volume Controller 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:

  • Before you set the quorum disk with the chquorum command, use the lsquorum command to ensure that the MDisk you want is online.
