To display summary information for the MAID shelves and RAID sets (LUNs):

ov_copan list [device_or_shelfID]
ov_copan listluns [device_or_shelfID] [-m raidlist] 

To display more detailed information about RAID sets, volumes, or drives:

ov_copan listinfo [device_or_shelfID] [-m raidlist] [-v] 
ov_copan listvols [device_or_shelfID] [-m raidlist] 
ov_copan listdrives [device_or_shelfID] [-m raidlist] 

For details about the variables, see “Summary of the ov_copan Command Syntax” in Chapter 2. For more information, see the ov_copan(8) man page.

If you accidentally delete an OpenVault component, you can repair the damage by updating the OpenVault component information for the shelf:

ownernode# ov_shelf update shelfID

If you try to delete a volume that contains data, you will get an error message. For example:

dmfserver# dmvoladm -l maid_ls -c "delete C00A00"
delete: VSN C00A00 ignored - usage is not zero.
Database was not modified.

You must flag the volume as sparse in order to cause DMF to move the data to a new volume before you can delete it. See “Deleting a Volume from a RAID set” in Chapter 6.
