The mmwindisk command
On Windows nodes, use the mmwindisk command to view all disks known to the operating system along with partitioning information relevant to GPFS.
For example, if you issue mmwindisk list,
your output is similar to this:
Disk Avail Type Status Size GPFS Partition ID
---- ----- ------- --------- -------- ------------------------------------
0 BASIC ONLINE 137 GiB
1 GPFS ONLINE 55 GiB 362DD84E-3D2E-4A59-B96B-BDE64E31ACCF

Where:
- Disk
- is the Windows disk number as shown in the Disk Management console and the DISKPART command-line utility.
- Avail
- shows the value YES when the disk is available and in a state suitable for creating an NSD.
- GPFS Partition ID
- is the unique ID for the GPFS partition on the disk.
The mmwindisk command does not provide the NSD volume ID. You can use mmlsnsd -m to find the relationship between NSDs and devices, which are disk numbers on Windows.
