Dell OpenManage is certified on certain updates on RHEL releases. We recently tried to install OpenManage on RHEL 4 update 2 and the IPMI driver would not load. Support told me that I needed to get to update 6 in order for it to work. Instead, I only updated the kernel and kernel-devel package and was able to get OpenManage to work. However, when I look at /etc/redhat-release, it still says update 2.
My question is, what does it take for that the file to officially get updated to the next "update" number? I know that if I do a full update through up2date, the OS will get updated. What is the specific part of the update that tells the OS to now display that it is at the next "update" release?
