There is an upgrade path that must be followed if you are currently at an older code level. The appliance will warn you if you attempt to upgrade from a level that is too old. What release are you currently at?
There is also a document that may help:
Sun Storage 7000 Unified Storage System: How to upgrade a clustered system (Doc ID 1447284.1)
Ended up needing an Engineer, there were all sorts of problems with this storage (I inherited it).
Nearly there thou.
I'm looking around trying to find AOM setup info rather than be stuck on a 'tip' session.
This is not clustered and the current SW/FW is SunOS Release 5.11 Version firstname.lastname@example.org,1-1.11 64-bit.
