Hello Lars,
Thank you very much for your mail.
Well, unfortunately I don't have a choice and musst use kernel 2.4 :-(
But therefore we use mostly Suse :)
Any more options ? We tried the qlogic fail-over driver. But it looks like
that this driver are unable to handle the way over 2 fabrics to a lun.
Regards,
Martin Lonkwitz

You should use DM multipath. md multipath isn't going to perform well for you in 2.4 (unless you're using the SLES8 kernel, which is hacked up quite a bit).
With 2.6, Device-Mapper has been choosen for the multipath IO to be implemented in.
