Kevin & Georg,
 
I didn't see the original request, so I'm not sure which Tape Alert flag 19h you're referring to or the exact question.  Regardless, none of the current Tandberg Data US-designed products set this flag.  (Georg has already received a response for our Oslo-designed products.)
 
My best guess at the intended usages:
 
    SMC-2 Tape Alert 19h - Operation invalid at this time.  Probably used to indicate operations that are currently not possible (e.g. move medium involving an open I/E Port)
 
    SSC-2 Tape Alert 19h - Redundant interface port has failed.  Only applies to multi-ported drives.  (e.g. FibreChannel GBIC failure)
 
    ADC Tape Alert 19h - Dual port interface error.  The meaning is probably a reflection of the SSC-2 redundant port failure.  Under ADT & ADT-2, I suspect this can only apply to non-bridged libraries or libraries bridged through a multi-port drive.  (Odd that it's arbitrarily limited to dual-port in ADC.)

Action Items from yesterdays ADI meeting





Hello Kevin
 
Here is answer for our Action Item from yesterday’s ADI meeting:
Sorry for the delay. Are you the right person for this answeer?

To Action Item on Tape Alert flag 19h.
 
I have checked with Tandberg Data here in Oslo and they do not implement this flag in their libraries or loaders.
At least not in the libraries developed here in Norway. What they do in the libraries from Exabyte, now Tandberg Data
I do not know.
Our opinion here at Tandberg Storage is that this flag is some kind of bucket where you put all cases that does not fit anywhere else.
We generally do not like unspecified TA flags like this. We should either remove it or make clear that this is a flag that can be used to indicate that
The library has an unspecified problem. The action should probably be something like that “If the problem persist, call a service representative”.
Unless someone comes up with a more specific use for this flag, I would probably vote for the removal solution.
