Installing Redhat 4 U 4 on PowerEdge (hence forth referred as server) having QLogic 2310F fiber channel card and Xiotech Magnitude 3D SAN [san booting linux]

 

Steps:

 

  1. Connect server to the fiber switch over the fiber cable
    1. Note the switch port
  2. Go to the QLogic utils <ctrl –Q> when booting the server
  3. Note the WWN number of the qlogic card.
  4. Do the zoning on  the fiber switch
  5. Go to the Xiotech san (ICON)interface.
  6. Assign a lun to that WWN number
  7. On the server side do the setting required for booting from windows.
    1. Refer QLogic guide.
  8. Boot from the Redhat disk 1
  9. Follow the standard procedure
  10. After it says anaconda running, a new and better gui would come up. When it does. Go to the console <ctrl> <alt> <F2>.
  11. Cat /proc/scsi/qlaxxx/0 or it can be 1 depending on the availability of scsi devices
  12. Check if there are ‘*’ on the last lines
  13. If they are there then
  14. Do echo “scsi add-single-device <scsi deviceid> 0 0 <lun number>” > /proc/scsi/scsi
  15. Generally if raid array is disabled scsi id would be 0 and lun number depends on the setting done on the SAN.
  16. Do cat /proc/scsi/qlaxxx/0 or it can be 1 depending on the availabity
  17. Check if there is some change in the line which were having ‘*’ previously. One line should not have ‘*’ on it. If there is no change probably there is some error while giving the echo command. Do it again
  18. Go to the gui installation menu <ctrl> <alt> <F2>.
  19. Proceed towards the installation
  20. Choose the correct physical disk while installation. DO NOT INSTALL ON LOCAL DISK. You can check the disk sizes to insure this.
  21. Once you finish with the installation.
  22. Again boot from the Redhat disk
  23. But in the rescue mode.  : linux rescue
  24. When the anaconda starts again to console
  25. Do steps from 10 to 18
  26. Proceed fwd. it will search for the already installed Redhat partition
  27. go go go
  28. Continue when it ask you to search for them
  29. chroot /mnt/sysimage
  30. Go to /etc/modprobe.conf
  31. Add a entry to it --- > options scsi_mod max_luns=255 default_dev_flags=0x242
  32. Make the ram disk again
  33. Go To /boot
  34. mkinitrd –f –v <kernel image name you want to create for>  < kernel name> example mkinitrd –f –v initrd-2.6.9-42.ELsmp.img 2.6.9-42.ELsmp
  35. You are done!! Reboot. Make sure BIOS is set to boot from qlogic card.
