I had executed the same command with the "-report_disc " option. And it is indeed showing that there's a descrepancy.
The result shows the 2 NDMP drives I've got configured to be missing. The thing is, the other one is non problematic at all.
From the -report_disc result, it shows that the non-problematic drive's path and the newly replaced drive path to be the same. Though, from GUI, you will see that the newly replaced drive has a different path.
Scan detects both drive and even shows their serial number.
I am thinking of deleting the object of the newly replaced drive but my concern is that, will it ask me for the NDMP password when I tried adding it back?
