I need to do a new CentOS net install on a new server having the Supermicro X7DVL-3 motherboard: http://www.supermicro.com/products/motherboard/xeon1333/5000V/X7DVL-3.cfm Based on that info I assume the board having a "8x SAS Ports via LSI 1068E Controller". We received the server with 3 drives + 1 spare as hw RAID-5 preinstalled. During bootup I see that the drives are initialised and everything seems ok. The issue I am facing is that when trying to install CentOS no hard drives are recognised. I am a bit confused as others have reported CentOS 5.3 and 5.4 working "out of the box" with the same controller: http://www.linux-archive.org/centos/287219-installing-centos-5-4-64bit-server-lsi-sas-1068e-controller.html So I assumed that the megaraid_sas driver shipped with CentOS should support the controller? What confuses me also is the output of lspci: MegaRAID SAS 3208 ELP Does this mean its not the 1068E controller inside but something else? Or CentOS misidentifies it? So I assume the controller is not supported and I need a binary driver for it. For 1068e it should be: http://www.lsi.com/storage_home/products_home/standard_product_ics/sas_ics/lsisas1068e/index.html and the driver I need is inside the file mptlinux-4.26.00.00-1-rhel5.5.x86_64.dd.gz But how do I go applying this driver during installation as the server has no floppy drive? And what happens if I get the driver installed and then the server's kernel is updated? Do I need reinstall the driver somehow? Best regards, Peter
