Problem



A backup or duplicate job to a deduplication folder fails because it thinks there is already media in the virtual drive. 


Error



V-79-57344-33037 - Error - Mount failed.
Physical Volume Library Media not found.
V-79-57344-33037 - Unable to acquire device for the specified pool and media 

Environment



 

 


Cause



A cache coherency problem occurs when multiple servers are accessing the same target deduplication device.  One server finishes using the virtual drive in the deduplication folder and removes the virtual media, but the other server doesn't recognize the change.  When the other server attempts to use the virtual drive, it thinks there is still media in it, and produces the error.

When this error occurs, a line such as the following will be placed into the adamm.log file.

[2342] 12/04/12 23:21:33.316 DeviceIo: ostscsi: Image 144 is already in drive 2
