M204.2734  IARV token error - return code​=​token2​,​ reason code​=​x'hexValue'

The IARV64 z/OS system service failed with the indicated error. IARV64 system services are required when above the bar storage is requested, most likely as the result of the setting of the NUMBUFG CCAIN parameter, which requests above the bar disk buffers.

System manager response: Consult the IARV64 documentation in the "Authorized Assembler Services Reference" for the release of z/OS being run.

In the unlikely event that this is not helpful (since this error should not occur in normal use of any above the bar storage facilities), contact Technical Support.
