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? > Another alternative is the linux-driver for the SUN T3.

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. --=20 Tracy Reed http://www.ultraviolet.org This is Linux Country.
