Currently i'm away from the server and can read only dmesg from 
equivalent one (that is up now)
amr0: <LSILogic MegaRAID 1.51> mem 0xfc0f0000-0xfc0fffff irq 28 at 
device 10.0 o
n pci3
amr0: <LSILogic MegaRAID SCSI 320-1> Firmware 1L19, BIOS 1.04, 64MB RAM
But i do not remember the exact card name :(

jbod? What do you mean? just to attache them to the plain SCSI 
controller and try to boot? (it should not work because they have LSI 
format of some kind i think). Or there is a way to do this on the 
controller itself?
And because of multiple Hot Spare disks were used (drives were 
migrating) i'm not sure which drive is the RAID1 part and which is Hot 
Spare.

And the matter is that i do not care alot about RAID1 (it is OS), but i 
do care about RAID5 - it is data.

Best regards,
Anton
