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
- Resolve any known Fibre Channel network
problems.
- 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".
- If the customer is unable to make the appropriate changes, ask
your software support center for assistance.
