Device mapper multipathing

Hi,

Is anybody who has used device mapper for Linux willing to share their experience?

I have been using Qlogic multipathing so far with the qla2300_conf module on RHEL3. No problem with it, but I am moving to RHEL4 and the needed qla2xxx_conf module is missing from their rmps distribution. So instead I have done a few tests with device mapper multipathing, seems to work fine so far, but nothing can beat real world experience.

Thanks,
L.
