[OmniOS-discuss] Only grub after boot

[Paul B. Henson]

Josh, did you ever try booting the 2tb drive off the sata controller?

When the box posts, does the hba bios properly report the size of the 2tb drives? When I first installed my lsi hba with 3tb sata drives, it showed them as invalid during post. They worked fine with the os, but the hba bios didn't recognize them. After I updated the hba bios, it properly reported them as 3tb drives. Given grub relies on the hba bios to access the drive, if it doesn't recognize the drive it won't work. 

Btw, his pool does have ashift=12, they are 4K drives. But that shouldn't matter to grub, particularly stage1 loading stage2, which just uses bios calls to read raw sectors? That's where it's failing.

It seems as though there is an issue with the Seagate ST2000NX0243 (2TB) drives, can anyone corroborate this or recommend a good method for running disk diagnostics / verifying OmniOS compatibility?
