Subject: [gentoo-kernel] LiveCD installation not recognizing megaraid RAID set
Date: Mon, 27 Jul 2009 09:22:18
Message-Id: 5185b3ce0907270222w2e3fb8cbuba3c08295474e8d3@mail.gmail.com
1 I was trying to put gentoo on a dell poweredge 1950 quadcore xeon machine
2 with three disks connected to a lsi PERC 5/i raid controller. In the BIOS
3 settings, all three disks were added to the controller for a RAID5 set up.
4 When I boot from LiveCD (2008 version with 2.6.24-r5 kernel) with
5 dmraid='-ay' option, it came up not recognizing the RAID set, as I only saw
6 "control" under /dev/mapper. modprobe megaraid was okay, so was modprobe
7 raid5. Under /dev, I only saw sda, but there was no sdb, sdc. So it looked
8 like there was only one disk but the system did not recognize it as a raid
9 set. Booting from LiveCD with dmraid='-ay' doscsi didn't help. I got the
10 same result. If I did a dmraid -ay in bash, I got "No RAID disks". Could
11 anyone point me to some instructions on how to make Gentoo recognize the
12 PERC 5/i RAID controller?
13
14 I tried both 32bit and 64bit gentoo and results were the same.
