Re: LSI MegaRAID installation

[steve%prd.co.uk@localhost (Steve Blinkhorn)]

Fujitsu 
Tech Support tell me the chip is vendor 8086 product a106.

I have gone back to square one, initialised a pair of disks in RAID 1
mode, set the BIOS to RAID rather than AHCI mode, and see from dmesg
that this configures at ahcisata0.

According to Ubuntu it is an LSI SAS-3 3108 (Invader).

So: is there currently no driver? is there something I am not doing
correctly so that the RAID controller is not recognised?  or am I just
misunderstanding what I should expect to see in the install process (I
was expecting to see one virtual disk to partition, not two physical
disks).
