[OmniOS-discuss] Problem with passed-through HBA

[alka]

I use about 20 IBM 1015 with OmniOS now (All-In-One passthrough and barebone) 
without problem (all my IBM 1015 are crossflashed to LSI 9211-IT mode).

Are you using vanilla IBM or crossflashed ones?
If the first is true, reflash the IBM.

(I use OmniOS/OI only so cannot say if this is a ZOL -> Solaris problem)
