Right, that is in agreement with both the Avago whitepaper and the
bits from the HP web site.

The on-board 2308-4i has a RAID-1 set connected, configured in the BIOS
before installing the OS. From dmesg:
**
scsi 0:1:0:0: Direct-Access LSI Logical Volume 3000 PQ: 0 ANSI: 6
scsi 0:1:0:0: RAID1: handle(0x0143), wwid(0x0dafbe8ecd4f4330), pd_count(2), type(SSP)
scsi 0:1:0:0: qdepth(128), tagged(1), simple(1), ordered(0), scsi_level(7), cmd_que(1)
**
So, one of these must be true:
1) The machine came from HP with the IR firmware, yet MegaCli64
does not work on the 2308-4i. For the record, it dies because
/dev/megaraid_sas_ioctl_node is not created when MegaCli64 is run,
as it is on PowerEdge machines.
2) The machine came from HP with the IT firmware, yet there is some
way to create a RAID-1 in the BIOS with it.
3) There's something I'm missing and/or I'm completely barking mad.
Any further clues appreciated.
Cheers,
Zube
