Hi Vincent,

I don't see a tape drive in the message (just the library), so I would
suspect the library itself. You might find these documents useful:

https://www.ibm.com/support/knowledgecenter/en/SSGSG7_7.1.1/com.ibm.itsm.msgs.server.doc/ioerrorcodes.html
https://www.ibm.com/support/knowledgecenter/SSGSG7_7.1.1/com.ibm.itsm.msgs.server.doc/ioerrorcodes_ascdesc.html#ioerrorcodes_ascdesc

Key=04 == "hardware error"
ASC=15 ASCQ=01 == "Mechanical positioning error"

The library itself might have more information in its logs.
