Hi dm-developers,

I'm having problem with multipathing device-mapper with my linux server, 
but this was resolved by Thread "multipathing flip flopping on Sun 6140" 
very well 
(http://www.redhat.com/archives/dm-devel/2007-August/msg00066.html)

The configuration is the same:

X4600 Server
2 HBA's Emulex
SAN STK6140

but in dmesg i have the following error message:

Buffer I/0 error on device sdf, logical block 0
end_request: I/0 error, dev sdf, sector 0

Did you know the error message?

Thanks,
Gustavo Riveros
