Hello!
To your first question, GPFS is a full device allocation, therefore, anything you wish to allocate will be consumed as an NSD.
Regarding your second question, yes, that disk is more than likely empty and therefore can be used for GPFS.
Finally, GPFS can run on one node (a single node quorum) and can have additional nodes added to it later. Make sure you have good time synchronization (xntpd) and decent performing disk storage.
Best regards,

One more thing, GPFS is pretty tolerant, just make sure you define "dataOnly" and "metadataOnly" disks when you create your NSDs (mmcrnsd). In this case, allocate 'x'-amount of storage for dataOnly NSDs and a relatively small disk for metadataOnly.
Good luck. If you have any questions, let me know.
