<p>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></o:p></p>
<p><o:p> </o:p></p>
<p>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></o:p></p>
