Subject: [Caos] hardware RAID for HP DL165 G6 server
Message-ID: <494906.94330.qm@web111301.mail.gq1.yahoo.com>

Hi All,

I've added a few new nodes to an existing CAOS Linux/Perceus 1.5 cluster. 
It all worked fine, Perceus detected them and booted without any problems, except that it doesnt see the local disks. Cannot see anything like them in /dev/.

Those are SAS disks attached to a hardware RAID controller. HP has the driver for it, mpt2sas, on their but it is a binary and compatible only with RedHat kernels, while my CAOS installation runs 2.6.31.6-2 now on the nodes. 

lspci says: 
RAID bus controller: Broadcom BCM5785 (HT1000) SATA Native SATA Mode


Could you please advice me, whether there is a way to use this controller with CAOS kernel? I'm pretty happy with how the OS works, so I wonder if there is a way to find/install a driver for the RAID.
