We do have some qlogic cards currently, but that's in a separate environment using SecurePath and Active/Passive MSA.
Thanks, Simon
Solved! Go to Solution.

Re: QLogic or Emulex with SAN/XP12000, given the choice?
Qlogic drivers are built into the Linux kernel, making the overall installation administration process somewhat easier.
Mostly though I end up replacing the drivers with the latest from Qlogic.
Emulex drivers may require you build a new initrd ram disk manually. Not difficult if you have the right drivers.

Re: QLogic or Emulex with SAN/XP12000, given the choice?
could check these steps
Here is the plan for handling the lpfc module.
├в ┬в Boot in single user mode or comment the fstab for the SAN volumes and come up with new kernel.
├в ┬в reinstall the lpfc rpm
├в ┬в Copy the old /lib/modules/2.4.21-47.ELsmp/kernel/drivers/scsi/lpfcdd.o to the corresponding new kernel location(/lib/modules/2.4.21-53.ELsmp/kernel/drivers/scsi/lpfcdd.o)
├в ┬в Take a backup and Edit the /etc/modules.conf and comment the entries for lpfc
# grep lpfc /etc/modules.conf
alias scsi_hostadapter1 lpfcdd
alias scsi_hostadapter2 lpfcdd
├в ┬в Take a backup of the existing initrd image and create a new one.
mkinitrd /boot/initrd-2.4.21-53.ELsmp.img 2.4.21-53.ELsmp
├в ┬в Revert the changes on /etc/modules.conf
├в ┬в Reboot to check everything works fine with the 3rd party kernel module (lpfc).
