[OpenIndiana-discuss] OI 151_a7 crashing when trying to import ZFS pool

[alka]

On OI, a LSI 9211 reflashed to IT mode + an LSI expander is the best solution.

In future the LSI 9207 is a better option (comes with IT firmware out of the box)
But this controller is quite new. While OmniOS supports it already I have heard of problems with current OI 151a7
