MASLIB Return Code 08, Reason Code 0130

Symptom

When using MASLIB to add a volume to an MTL, the following error message may occur:

M VOLSER EDCMAS01 00001 MCE RETURN CODE = 0008, REASON CODE = 0130

Resolution

The combination of RC08 with RSN130 is not documented in at least some versions of the IBM DFSMSdfp Diagnosis Reference. It means that the specified volume already resides in this tape library. It is issued by CBRBLMCE and was added with OW45305.

Besides the situation of attempting to manually add a volume more than once to an MTL, this error may also occur if you are using RMM, because RMM automatically adds scratch volumes to the MTL. In this case you do not need to run MASLIB to add the volumes.
