MDisks are managed by using the MDisks by Pools pane. To access the MDisks by Pools 
page, browse to Pools → MDisks by Pools, as shown in Figure 6-9.
Figure 6-9   MDisks by pool
The pane lists all the MDisks available in the system under the storage pool to which they 
belong. Both arrays and external MDisks are listed. For instructions on operations with array 
MDisks, see 6.2, “Working with internal drives and arrays” on page 207. To implement a 
solution with external MDisks, see 6.3, “Working with external controllers and MDisks” on 
page 227.
To list all MDisks visible by the system with the CLI, use the lsmdisk command without any 
parameters. If required, you can filter output to include only external or only array type 
MDisks.
