INSTALLING QLOGIC FC DRIVER ON RHEL 4 - 4/18/2017

1]  mkdir /qla2xxx

2]  cd /qla2xxx

3]  Download the driver source files, 
    qla2xxx.vx.yy.zz.dist.tgz
 
    [ex:  qla2xxx-8.01.04b6.dist.tgz ]

    NOTE: SOMETIMES THE SUFFIX IS WRONG
          If not "*.tgz" rename it to *.tgz"

4]  tar -zxvf qla2xxx.vx.yy.zz.dist.tgz

6]  cd  qlogic     [/qla2xxx/qlogic]

7]  ./drvrsetup

8]  cd qla2xxx-x.yy.zz  [ex: qla2xxx-8.01.04b6 ]

7]  ./extras/build.sh new  (both cleans & builds)

TO LOAD DRIVERS MANUALLY:

   modprove -v qla2400

TO UNLOAD DRIVERS MANUALLY:

   modprobe -r qla2400

TO MAKE A RAMDISK IMAGE TO LOAD THE DRIVER:
(assumes you've done steps 1 through 7)

A] ./extras/build.sh install  (installs .ko files)

B]  Edit /etc/modprobe.conf file and add these lines:

alias scsi_hostadapter2 qla2xxx_conf  # SANsurfer use only
alias scsi_hostadapter3 qla2xxx       # common module
alias scsi_hostadapter4 qla2400       # for QLA24XX cards

options qla2xxx ql2xfailover=0
options scsi_mod max_luns=255    # <<< NOT max_scsi_luns

C]  cd /boot

D]  cp -f initrd-2.6.[kernel version].img initrd-2.6.[kernel version].img.bak

    [ex:  cp -f initrd-2.6.9-22.ELsmp  initrd-2.6.9-22.ELsmp.bak ]

E]  mkinitrd -f initrd-2.6.[kernel_version].img [kernel_version]

    [ex: mkinitrd -f initrd-2.6.9-22.ELsmp  2.6.9-22.ELsmp ]

F]  reboot the system to load the RAMDISK image w/QLogic driver.

SNIA API LIBRARY PACKAGE:
(assumes you've done steps [1] through [7], above.

1]  cd /qla2xxx/qlogic   (you may already be there)

2]  ./libinstall  (installs/sets up HBA API library)

TO UNINSTALL THE API LIBRARY:

    ./libremove

YOU MUST DISABLE FAILOVER SUPPORT IN THE DRIVER:
To disable in the modprobe.conf file, add this AFTER the driver:

options qla2xxx qla2xxx ql2xfailover=0

TO MANUALLY DISABLE FAILOVER:

    insmod qla2xxx.ko ql2xfailover=0; insmod qla2400.ko

    I'M NOT SURE THAT THIS METHOD (ABOVE) REALLY WORKS IN RH.
