19# Usage:
20#   mmdelnsd {"DiskName[;DiskName...]" | -F DiskFile}
21# or
22#   mmdelnsd -p NSDid [-N Node[,Node]]
23#
24# where:
25#
26#   "DiskName[;DiskName...]"  is a ";"-separated list of NSD names.
27#
28#   DiskFile                  is the name of a file containing the names
29#                             of the NSDs to be deleted.
30#
31#   -p NSDid                  is the NSD volume id of a GPFS NSD.
32#
33#   -N Node[,Node]            is a list of nodes to which the disk is attached.
34#                             If not specified, the disk is assumed to be
35#                             directly attached to all nodes in the cluster.
36#                             Although -N is processed the same as for other
37#                             GPFS commands (i.e., you could also specify
38#                             a longer node list, a node file, or a node class),
39#                             only the first two nodes will be used.
40#
41# Note:  The second format of the command is intended primarily for use
42#        after a successful removal of the disk from the mmsdrfs file,
43#        but a failure to clear the NSD volume id of an NSD disk.
