We did have our array upgraded to 3.1.3
I cant claim it went totally uneventfull, but my upgrade succeded, though with a strange task failed error:
2014-04-04 123330 CEST Error t2cpg NL_r6 is already associated with an AO configuration.
2014-04-04 123330 CEST Error Task exited with status 1
2014-04-04 123330 CEST Failed Could not complete task.
It made little sense to my why it would fail, since i only have a single AO, which is a three tier one. albeit it is not the one the array originally came with.
Its been running now for the last week without issue, and im moving into production tomorrow.
So crossing fingers ofcause
