10.0pt;font-family:Arial;color:navy'>There seem to be lot of issues with OCFS2
related to failover and all. We tested the same scenario, we brought down
one HBA and the node went down, even though there was another HBA and we were
using PowerPath. We brought down one SP in our Clariion, node went down, even
though the second SP is still functioning. We have decided to not to use OCFS2
and instead go with ASM. I opened a ticket with oracle to ask when ocfs2 will
be certified, they didn't give me any time frame instead suggested ASM is
the way to go.<o:p></o:p></span></font></p>
