This looks like some multipath relate issue. It looks like the multipath devices are not working properly. Can you please post the output of # multipath -ll Since RHEL 6.2 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.
Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
It's been 4 years since I asked for more information on this bug. |
