Removing Drives with cfgadm

Newer Sun kit has a feature where when you unconfigure an internal drive for removal a blue light comes on indicating the device is ready for removal. This is quite useful when you are performing break fix to a remote location, so that the engineeers know which drive to pull.
This works when removing tape drives as well as in the example below
