How do you delete a drv device

To delete a device the command file is

delete dev symdevname;

symconfigure automatically adds ', raidset=false;

with drv devices it does not for some reason so the command file must contain the full syntax

delete dev 'symdevname', raidset=false

if the drv has been used then it will be in the below state

     DRV Device                    Standard Device                  Status
-------------------- ------------------------------------------- ------------
              Inv.                                        Inv.
Sym           Tracks Physical                        Sym  Tracks DRV <=> STD
-------------------- ------------------------------------------- ------------

Not Visible     06A2               0 Not Visible     037E      0 SplitNoInc

so in order to delete the device you must convert it first

cmd file syntax:

convert dev 06a2 to unprotected;

then the device can be deleted as above
