IBM TS 4300: Got empty SNMP response

Hi,
sorry for this confusion, I’d looked in the wrong file. The tape library will be detect by this scan function:

def scan_ibm_tape_library(oid):
    return oid(".1.3.6.1.2.1.1.2.0").startswith(".1.3.6.1.4.1.32925.1")

If this not in the bulkwalk, then checkmk will not check the needed OIS’s. The needed data für some checks is in the wolk. Did you try with SNMP V1 or SNMP v2C?

Regards,
Christian
