EMC – VNX: USM reports an error “Assistance needed for upgrade”

If you’re trying to do an OE upgrade on a VNX you might get the following error after you’ve run through the “Prepare for Installation” phase.


Turns out you just need to upgrade USM to the latest version. You can do this manually or via USM. Further information on this error can be found on support.emc.com by searching for the following Primus ID: emc321171.

Incidentally, I’d just like to congratulate EMC on how much simpler it is upgrade FLARE / VNX OE nowadays than it was when I first started on FC and CX arrays. Sooo much nicer …
