This chapter discusses the following:
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.
