Fiber channel disks are not working in CentOS 5.5.

**Pandeyji** · 06-05-2011

Hello everyone, I am doing one experiment on my system and I am facing some problem within it. I am trying to set up a new CentOS 5.5 server with an LSI 7402XP fiber channel HBAcard connected with 28 SATA drives. I have connected disks and there is no RAID and LVM. After connecting I have rebooted the system, it is showing me /dev/sdc/ and on entering it shows /sys/class/scsi_disk. When I am selecting the anyone option it shows me status as running. Whenever I am trying to or write drives directly the dd gets failed . so guys cab anyone help me this matter. I am waiting for your replies.

Hey I have gone through to your problem, and I think this is the problem of kernel. Just go through to below log and change as per requirement:

Code:

[root@localhost dev]# /sbin/mkfs /dev/sdc
mke2fs 1.39 (29-May-2006)
/dev/sdc is entire device, not just one partition!
Proceed anyway? (y,n) y
mkfs.ext2: Device size reported to be zero.  Invalid partition specified, or
        partition table wasn't reread after running fdisk, due to
        a modified partition being busy and in use.  You may need to reboot
        to re-read your partition table.

[root@localhost dev]# dd if=/dev/sdc of=/tmp/foo

Hello I just wanted to say thanks to all who have helped me for this matter. I have tried all the methods and trick on my system but finally above posted content worked for me. I installed kernel independent mpt fusion driver from official website of Linux. After that I tried installing open Solaris on my system and it worked for me, it made the folder /dev/dsk. And finally I got success in it, thanks a lot guys without you it was not possible for me to do such big operation. Enjoy the Technology.
