Cool! I think I've heard about this patch once before. I will have to give
it a try.  Dual-pathing is something we have been wanting for a long time.
Do you think this patch something that is likely to one day be merged with
the kernel such that we can count on it being with us for a while?

Does anyone know of any driver for Clariion based disk arrays? I don't
think the Sun T3 uses Clariion does it? We have a ton (many tons,
literally :) that we are currently using with Solaris that we would love
to be able to attach to Linux systems. These things are hardware RAID
arrays with dual RAID controllers in them. When one RAID controller fails
something special has to be done to transfer the LUNs from the dead
controller over to the live one. They call this "ATF" or "Automatic
Transparent Failover" and they don't seem to ship it for Linux. Only NT
and Solaris. I've tried talking them into considering it but not had any
success.

This is Linux Country. On a quiet night, you can hear Windows NT reboot!
