Kris: I really do not want to have to downgrade the OS. Unless there was some change in the kernel API calls Power Path uses, it really should not matter because the basic kernel version would be the same. Yes there would be point versions. The Power Path driver is a kernel loadable module. When the kernel does change, then there is a directory that has to be created in the new kernel tree and rpm run again with the --replacepkgs option to reinstall the modules. I had to do that several times for RH AS 4.X. Another reason is because we compile our Application on the systems and expect our customer to keep their system up to date. It really makes it very complex to tell them to upgrade everything but the kernel until you hear different. Then for all I know there could be several kernel upgrades say from 5.1 to 5.4 and the driver is only supported up to 5.2 or will be. Myself and our customers can not easily if at all select the one to upgrade to. The latest one is the only one shown by yum.

I think the issue is that the kernel module is compiled by EMC for specific kernels, not dynamically on installation. The reason I got was to ease the support load for EMC. I really, really like PowerPath and will do what I need to do to run it, even if that means running a slightly older RHEL release.

I know, your first thought is, so why are you asking this list about it and not EMC? I have asked EMC indirectly (see below) and did not really like their answer. I have some new systems that I installed RH EL 5.1 on with the assumption that EMC Power Path would be supported on it. And I think it was, is. I have Power Path install on some other systems running RH AS 4.6. Because the SAN is from EMC is the reason our SAN group wanted me to use Power Path. While waiting for our SAN group to allocate disk space and cable up the systems I have been keeping the system up to date via yum. Along the way the kernel version has changed and the over all system is now RH EL 5.2. So when the SAN group told me the SAN was all connected and I needed to install EMC Power Path is when it was identified there is a problem. It will not install. When rpm is run with the latest file from EMC I get an error stating the software is for RHEL5. That's correct, just RHEL5, no dot anything. I had our SAN group contact EMC and the response back from EMC was RH EL 5.2 will not be supported until the 4 QT of this year. So my first question is has anyone else run into this problem? If so what did you do? I know I can probably use the Multi Path software that comes with Linux, but I would like to keep all my systems configured as mush the same a possible. This just makes dealing with the SAN group a lot easier.
