202 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
Example 6-7   Using lsmdisk (some columns are not shown)
IBM_Storwize:ITSOV7K:superuser>lsmdisk -filtervalue mdisk_grp_name=Pool0
id name   status mode  mdisk_grp_id mdisk_grp_name capacity ctrl_LUN_#
0  mdisk0 online array 0            Pool0          826.4GB 
Delete
A storage pool can be deleted with the GUI only if no volumes are associated with it. Select 
Delete to delete the pool immediately without any additional confirmation.
If there are volumes in the pool, Delete option is inactive and cannot be selected. Delete the 
volumes or migrate them to another storage pool before proceeding. For more information 
about volume migration and volume mirroring, see Chapter 7, “Volumes” on page 241.
After you delete a pool, the following actions occur:
/SM590000All the external MDisks in the pool return to a status of Unmanaged.
/SM590000All the array mode MDisks in the pool are deleted and all member drives return to a status 
of Candidate.
To delete storage pool with CLI, use rmmdiskgrp.
Properties
Select Properties to display information about the storage pool. Additional information is 
available if you expand the View more details section. By hovering over the elements of the 
window and clicking [?], you see a short description of each property, as shown in 
Figure 6-16.

Note: Be extremely careful when you use rmmdiskgrp command with -force parameter. 
Unlike the GUI, it does not prevent you from deleting a storage pool with volumes. This 
command deletes all volumes and host mappings on a storage pool and these cannot be 
recovered.
