Fiber channel disks are not working in CentOS 5.5.
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. |

Re: Fiber channel disks are not working in CentOS 5.5.
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 0+0 records in 0+0 records out 0 bytes (0 B) copied, 4.8e-05 seconds, 0.0 kB/s [root@localhost dev]# yes | dd of=/dev/sdc dd: writing to `/dev/sdc': No space left on device 1+0 records in 0+0 records out 0 bytes (0 B) copied, 0.00091 seconds, 0.0 kB/s |

Re: Fiber channel disks are not working in CentOS 5.5.
I have gone through to the above posted log and I came to know that if you want to that log on your console then you need to follow this path /var/log/messages and change it wherever necessary. All the best! See tye below entries: Code: May 4 11:23:05localhost kernel: device-mapper: uevent: version 1.0.3 May 4 11:23:05 localhost kernel: device-mapper: ioctl: 4.11.5-ioctl (2007-12-12) initialised: dm-devel@redhat.com May 4 11:23:05 localhost kernel: Fusion MPT base driver 3.04.13rh May 4 11:23:05 localhost kernel: Copyright (c) 1999-2008 LSI Corporation May 4 11:23:05 localhost kernel: Fusion MPT FC Host driver 3.04.13rh May 4 11:23:05 localhost kernel: GSI 20 sharing vector 0x5A and IRQ 20 May 4 11:23:05 localhost kernel: ACPI: PCI Interrupt 0000:0b:00.0[A] -> GSI 18 (level, low) -> IRQ 90 May 4 11:23:05 localhost kernel: mptbase: ioc0: Initiating bringup May 4 11:23:05 localhost kernel: ioc0: LSIFC949E: Capabilities={Initiator,Target,LAN} May 4 11:23:05 localhost kernel: scsi6 : ioc0: LSIFC949E, FwRev=01031b00h, Ports=1, MaxQ=1023, IRQ=90 May 4 11:23:05 localhost kernel: GSI 21 sharing vector 0x62 and IRQ 21 May 4 11:23:05 localhost kernel: ACPI: PCI Interrupt 0000:0b:00.1[b] -> GSI 19 (level, low) -> IRQ 98 May 4 11:23:05 localhost kernel: mptbase: ioc1: Initiating bringup May 4 11:23:05 localhost kernel: ioc1: LSIFC949E: Capabilities={Initiator,Target,LAN} May 4 11:23:05 localhost kernel: scsi7 : ioc1: LSIFC949E, FwRev=01031b00h, Ports=1, MaxQ=1023, IRQ=98 |

Re: Fiber channel disks are not working in CentOS 5.5.
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. |
