could you please specify the exact kernel versions you are referring to? I'm not sure which version update 3 was. We are currently running 2.4.21-15.0.3.ELsmp. We can't really use a newer version, because we need IBM's sdd driver for SAN vpaths and they are slow in certifying new kernels ... maybe telling them about specific issues might speed up the process.
A lttle bit OT: I don't know the IBM thing but I expect it's all about multipathing some FC connected SAN disks. Maybe you also use qla2300 cards. We were forced to use HP's secure path for this. It's expensive and it's also never available for updated kernels in time. Now we are just using the multipathing/failover which is built in into the qla2300 drivers of the newest RedHat kernels and it works like a charm.
thanks for the info. I've told our systems people about this and they are now playing around with it. Our situation is probably a little more complicated than usual because of an additional layer of virtualization that is introduced by the IBM SVC stuff. There are four "raw" devices visible for each volume ...
