Subject: Direct disk access on IBM Server
Date: Tue, 19 Apr 2011 15:21:39 +0200 [thread overview]
Message-ID: <iok28i$tp6$1@dough.gmane.org> (raw)
I have recently got an IBM x3650 M3 server, which has a "Serveraid
M5014" raid controller. Booting from a Linux CD (system rescue CD) and
running lspci identifies this raid controller as:
LSI Logic/Symbus Logic Megaraid SAS 2108 [Liberator] (rev 03)
The controller works fine for hardware raid - I can open its bios setup
utility, and set up a RAID5 (or whatever) with the disks I have. The OS
then just sees a single virtual disk.
But I would like direct access to the sata drives - I want to set up
mdadm raid, under my own control. As far as I can see, there is no way
to put this controller into "JBOD" or "direct access" mode of any sort.
Does anyone here have experience with this card, or can give me any hints?
The only idea I have at the moment is to put each disk within its own
single-disk RAID 0 set, but then I don't get sata hot-swap
functionality, SMART, hddtemp, etc.
Thanks for any clues or hints,
David
