Determining the relationship between VDisks and MDisks using the CLI

You can determine the relationship between virtual disks (VDisks) and managed disks (MDisks) using the command-line interface (CLI).

Select one or more of the following options to determine the relationship between VDisks and MDisks:

To display a list of the IDs that correspond to the MDisks that comprise the VDisk, issue the following CLI command:
```
svcinfo lsvdiskmember vdiskname/id
```
where vdiskname/id is the name or ID of the VDisk.
To display a list of IDs that correspond to the VDisks that are using this MDisk, issue the following CLI command:
```
svcinfo lsmdiskmember mdiskname/id
```
where mdiskname/id is the name or ID of the MDisk.
To display a table of VDisk IDs and the corresponding number of extents that are being used by each VDisk, issue the following CLI command:
```
svcinfo 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 given VDisk, issue the following CLI command:
```
svcinfo lsvdiskextent vdiskname/id
```
where vdiskname/id is the name or ID of the VDisk.
