I thought it would work to upgrade only the kernel. It seems very strange that you have to upgrade all those userland utilities. Did you try with some RPM frontend like up2date that makes "clever" choices for you, mayhaps? If so try downloading the RPM and installing it directly with the rpm utility. When looking at the package description of the 2.6.18-36 RPM, I don't really see any conflict that should cause this - the conflicts are the exact same as in the latest RHEL5 non-beta kernel (2.6.18-8.1.10), so there's no reason why it wouldn't work to install the beta kernel directly without upgrading any other packages. I can't see any, at least. > I've downloaded and compiled the latest multipath source (0.4.8). Now > I need to compile the rdac hardware handler against my current kernel > source. Can anyone provide me with the latest, patched source? The source RPM is available from RHN. Go to Channels, then All channels, find Red Hat Enterprise Linux (v. 5 for [your arch here]), expand it and find the associated beta channel. Enter it, go to Packages and search for "kernel", follow the appropriate link and you should have a source RPM download link there. > Tore, I know you have it!

Now I'm hoping I can get > instructions on how to compile the rdac hw handler against my kernel. I'm using 2.6.23-rcX or the kernel from RHEL 5.1 beta. Or you can try to grab the RHEL5 (2.6.18-8.1.10) kernel sources as well as the source RPM for 2.6.18-36, copy over driver/md/dm-mpath-rdac.c and also add the relevant changes to Makefile and Kconfig, and with some luck you'll be able to build a module that's insertable on 2.6.18-8.1.10. But first I'd try some more to install the kernel from 5.1 beta. I'm quite confident it should work just fine.
