Unknown Collection Error


I have just started to see this error when it tries to collect from a pair of FAS3250s running 8.1.2:

Discovery:Error:Unknown Collection Error
Last Success:Today @ 10:30am
Last Attempt:Today @ 2:30pm
Illegal attempt to assign a primary resource key to null or unknown.

It was running fine before then.

Any thoughts?

Hi, I have the same issue.

FAS3250 8.1.3P1 7-Mode

OnCommand Balance

I also get the error message "Unknown Collection Error" on Statistics Collection.

Discovery seems fine.

Restarted the Virtual Machine Appliance but no success.

Please assist me.


We have been seeing this at a few sites. Please open a support case; they will triage, and get it to engineering as needed.


I too see this in my lab here in Scottsdale.


We've had this as well, restarting the service on OCB was the fix, unfortunately we lost the data during that time.
