Hi Raul, Yes, it seems like-stuff.
Thanks for pointing out the same still applies to RHEL5.6 . There is a opened
bugzilla at https://bugzilla.redhat.com/show_bug.cgi?id=649705
. Low priority, of course
(for Redhat), as no response at all. They seem
to ignore that sometimes we have to do demostrations to prospective customers,
etc, and the image of all these messages popping out from the console and the
logs are unforgettable. Alvaro De:
linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] En nombre de Martinez-Sanchez, Raul Hi Alvaro, I have also opened a
ticket with RedHat for the same reasons on rhel5u6 and a DS5020 and a DS3524
which I believe they are both active/active and multipath seems to treat them
as active/passive, but I guess this is for another mailing list. Raúl From:
linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Alvaro Hi, DOC-35489 only partionally
approaches the problem. I have it too, on a passive/active IBM DS4000 array and
RHEL5.5. I've excluded from lvm.conf any SAN partitions as per the note (and
also made a new initrd boot, as lvm.conf is included at boot time as the /
partition I have it LVM'ed) , but messages still apears on bootup. They always
dissapear when multipathd service starts and its scsi_dh_rdac discipline is
loaded. Even opened a case with
Redhat, and obtained the same response (but not workaround): "it's
entirely harmless, they are normal". Alvaro De:
linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] En nombre de Martinez-Sanchez, Raul Hi Balaji, According to RedHat
documentation some Storage Array Devices configured in active/passive mode and
using multipath will display this I/O error messages, so this might also be
your case (see https://access.redhat.com/kb/docs/DOC-35489),
this link indicates that the messages are harmless and can be avoided following
its instructions. The logs you sent do
not indicate anything related to fencing, so you might need to send the
relevant info for that. Cheers, Raúl From:

devices are in passive path. Environment : RHEL 5.4 & EMC SAN Please suggest how to overcome this issue. Support
will be highly helpful. Thanks in Advance
