CBR4101I   Library library-name Control Unit, Library Manager incompatible.

Explanation

An error has been detected during Library Automation Communication Services (LACS) processing for the MOUNT or DEMOUNT function. Library library-name returned a unit check in response to the mount or demount order. The library sense information indicates that the control unit and the library manager are incompatible for one of the following reasons:
  • The control unit and the library manager microcode levels are not compatible.
  • The sequence number of the control unit does not match the value known to the library manager.
  • The library manager has received a valid message type from the control unit, but it contains information not recognized by the library manager.

System action

The LACS request fails with a permanent error return code. Messages issued by the caller of LACS are written concurrently with this message.

Operator response

Search problem reporting databases for a fix for the problem. If no fix exists, contact an IBM® service representative to arrange for the appropriate microcode level to be installed in the control unit or the library manager, or both.

Programmer response

Resubmit the failing job.
