Retrieving and Interpreting Event Messages
Event messages generated by hardware monitoring can be delivered using a variety of notification methods.
To simplify receiving event messages you may want to use the email and/or textfile notification methods. Both
of these methods, which are included in the default monitoring, receive the entire content of the message so
you can read it immediately.
Methods such as console, syslog, and SNMP alert you to the occurrence of an event but do not deliver the
entire message. You are required to retrieve it using the resdata utility. For these methods, the event
notification will include a message similar to the following:
Execute the following command to obtain event details: /opt/resmon/bin/resdata
-R 392036357 -r /storage/events/tapes/SCSI_tape/10_12_5.0.0 -n 392036353 -a
It is important that you execute the command exactly as indicated, including the two critical number fields
that are indexes for the resdata entries.

the medium with a fresh one. Alternatively, if the medium is not
removable, the device has experienced a hardware failure.
