1330 A suitable managed disk (MDisk) or drive for use as a quorum disk was not found.

Explanation

A quorum disk is needed to enable a tie-break when some cluster members are missing. Three quorum disks are usually defined. By default, the cluster automatically allocates quorum disks when managed disks are created; however, the option exists to manually assign quorum disks. This error is reported when there are managed disks or image mode disks but no quorum disks.

To become a quorum disk:

  • The MDisk must be accessible by all nodes in the cluster.
  • The MDisk must be managed; that is, it must be a member of a storage pool.
  • The MDisk must have free extents.
  • The MDisk must be associated with a controller that is enabled for quorum support. If the controller has multiple WWNNs, all of the controller components must be enabled for quorum support.

A quorum disk might not be available because of a Fibre Channel network failure or because of a Fibre Channel switch zoning problem.

User response

  1. Resolve any known Fibre Channel network problems.
  2. Ask the customer to confirm that MDisks have been added to storage pools and that those MDisks have free extents and are on a controller that is enabled for use as a provider of quorum disks. Ensure that any controller with multiple WWNNs has all of its components enabled to provide quorum disks. Either create a suitable MDisk or if possible enable quorum support on controllers with which existing MDisks are associated. If at least one managed disk shows a mode of managed and has a non-zero quorum index, mark the error that you have just repaired as fixed.
  3. If the customer is unable to make the appropriate changes, ask your software support center for assistance.
  4. Run the fix procedure from the event log menu in the GUI.
