Failed while processing disk descriptor descriptor on node nodeName.
One of these errors can occur if an NSD server node does not have read and write access to the disk. The NSD server node needs to write an NSD volume ID to the raw disk. If an additional NSD server node is specified, that NSD server node will scan its disks to find this NSD volume ID string. If the disk is SAN-attached to all nodes in the cluster, the NSD volume ID is written to the disk by the node on which
the mmcrnsd command is running.
