I am trying to get multipath working an Intel Multi Flex server MFSYS25 with 2 SAS storage controllers. There are other postings in this forum about this as well as how-to here but none of these seem to work in my case so I am starting from scratch. Removed multipath-tools and multipath-boot packages etc. I am planning to create a wiki page for this configuration. Any help would be greatly appreciated.
On my first attempt, after installing multipath-tools and multipath-boot, I had to change my /etc/fstab UUID entries to dm entries in order for the discs to mount. I left my /boot/grub/menu.lst untouched, but multipath did not work:
