| 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. |
