Hi Richard,
<div class=""><br class="">
</div>
<div class="">I would echo the previous comment about having a test cluster where you at least do some basic functionality testing.</div>
<div class=""><br class="">
</div>
<div class="">Also, as I’m sure you’re well aware, a kernel upgrade - whether or not you’re upgrading GPFS versions - is an especially good idea on RHEL systems right now thanks to “Dirty Cow”.</div>
<div class=""><br class="">
</div>
<div class="">We do not generally install every GPFS PTF as it comes out … mainly we install PTF’s that fix problems we are encountering … but when we are upgrading GPFS we also generally take the opportunity to do a full yum update as well.</div>
<div class=""><br class="">
</div>
<div class="">HTHAL…</div>

I think GPFS upgrades are a fine opportunity to check the FAQ and update to latest tested/supported OS versions. But please remember to check all components in the "Functional Support Matrices", and latest kernel tested.<br class="">

As a general rule, when updating GPFS to a newer release, would you perform a full OS update at the same time, and/or update the kernel too?<o:p class=""></o:p></div>

Just trying to gauge what other people do in this respect. Personally I’ve always upgraded everything at once – including kernel. Am I looking for trouble?<o:p class=""></o:p></div>
