I'm reinstalling cluster nodes with SLES11-SP1. The nodes are boot on SAN and will use the official RDAC driver once installed. But during installation (boot from the network using PXE) there is no multipathing driver present and therefore some activities, like the search for disks and partitions are very slow.
I would like to modify the SuSE-supplied network-install initrd to use dm-multipath during installation. Multipathing with dm-multipaht works and I have a multipath.conf file. I can add those to the initrd just fine. But I'm stuck in how to get the module loaded and the multipathd daemon started automatically during the install process. There is a program called 'init', which is the SuSE installer.
How can I get my 'modprobe dm-multipathd' and 'multipathd' started before handing over control to the install program named 'init' ?
