To display a list of IDs that correspond to the volumes that are using this MDisk, issue the following CLI command:
```
lsmdiskmember mdiskname/id
```
where mdiskname/id is the name or ID of the MDisk.
To display a table of volume IDs and the corresponding number of extents that are being used by each volume, issue the following CLI command:
```
lsmdiskextent mdiskname/id
```
where mdiskname/id is the name or ID of the MDisk.
To display a table of MDisk IDs and the corresponding number of extents that each MDisk provides as storage for the specified volume, issue the following CLI command:
```
