Hannes, I'm confused that SLES 9 added a parameter, multipath=, to switch "off multipathing in the initrd, ie for the root fs"
but Novell says specifically for SLES 9 that "Currently, DM MPIO is not available for either the root or the boot partition, as the boot loader does not know how to handle MPIO." (see http://support.novell.com/techcenter/sdb/en/2005/04/sles_multipathing.html ) Puzzles me since my experience is coding the multipath= kernel parm on SLES 9 zSeries doesn't suppress, enable, or affect multipathing with multipath-tools. Can you be more detailed about the intent of the multipath= parm? Or point me to some documentation that explains use of this new feature? danke -------------------------------------------------------- This e-mail, including any attachments, may be confidential, privileged or otherwise legally protected.

The multipath= parameter is for switching off multipathing in the initrd, ie for the root fs. And as you already pointed out it's platform agnostic. Why did you think it's somewhat platform dependent?
