Using sam I can see the following two devices are unused
0/4/1/0.4.0 1 Unused -- 286102 COMPAQ BF3008AFEC тФВ
тФВтФВ 0/4/1/0.5.0 1 Unused -- 286102 COMPAQ BF3008AFE C
How do I figure out the size of these two disks?
Are these two disks or should I see one?
How do I find out the RAID level?
I dont see them as /dev/ciss but as standard SCSI disks.
Please help will be truly appreciated

Re: MSA30 - Need help
The MSA30 is a JOBD enclosure, does not create RAIDs by itself. You must do that on the SCSI adapter if it supports hardware RAID, or on the OS.
In an MSA30 the disks are all on the same channel, or 7 on one channel and 7 on another. In your case SCSI ID 0, 1, 2, 3, 4 and 5 are on the same channel, connected to the same controller, so there should not be any difference on how the OS sees them.

I dont see any SmartArray SCSI controller, which one is it being used for the disks?
Also, is there any guide that shows you how to create a RAID 1 with thouse 2 disks? can it be done from SAM?
Thanks

Re: MSA30 - Need help
C1010 Ultra160 Wide LVD A6829-60101
It's a dual channel SCSI HBA
On channel 0 you have the MSA30 with 6 disks
On channel 1 you have a DAT72
You have no SmartArray, so no hardware RAID.

Re: MSA30 - Need help
2 options:
- Mirror with LVM (from one bus to the other)
- buy a smartarray controller for hardware RAID
Hope this helps!

Torsten.
