HOWTO: Configuring the Fibre Channel Adapter

1. Edit/Verify the fiber host adapter module will load after the scsi host adapter modules.
• {to force the fiber host adapter to load AFTER the scsi host adapter modules, the fiber host adapter "qla2x00" must be listed after all the other scsi host adapters and must have the highest number. You must first move the line with "scsi_hostadapter qla2x00" below all the other scsi_hostadapter lines. Then renumber all the "scsi_hostadaptern" entries including the "scsi_hostadapter qla2x00" starting with blank (' ') and then '1', '2' and so-on.} 
  
  
2. Add the line "options scsi_mod max_scsi_luns=128".

3. Example:

   -- ORIGINAL modules.conf

   alias eth0 eepro100

   alias scsi_hostadapter qla2x00  # This line must be moved down below the

   alias scsi_hostadapter1 aic7xxx   # "alias parport_lowlevel parport_pc" line

   alias scsi_hostadapter2 ips

   alias eth1 e1000

   alias parport_lowlevel parport_pc

   alias usb-controller usb-ohci

   
   

   -- NEW modules.conf

   alias eth0 eepro100

   alias scsi_hostadapter aic7xxx  # scsi_hostadapter1 renumbered to scsi_hostadapter

   alias scsi_hostadapter1 ips    # scsi_hostadapter2 renumbered to scsi_hostadapter1

   alias eth1 e1000

   alias parport_lowlevel parport_pc

   alias scsi_hostadapter2 qla2x00   # After line has been moved and renumbered

   alias usb-controller usb-ohci

   options scsi_mod max_scsi_luns=128   # Added new line
   
   

4. mv /boot/initrd-2.4.2-2smp.img /boot/initrd-2.4.2-2smp.img.old [enter]

   mkinitrd /boot/initrd-2.4.2-2smp.img 2.4.2-2smp [enter]

   lilo [enter]

   Attach the fiber cable from the storage node to the Triton Controller.

   init 6 [enter] {to reboot the storage node}
