multipathing ?


our oracle(oracle 10G) server got a serious problem, the OS is SLES 9 SP4, two HBA adapters(QLogic 2340) with NetApp FC Storage(FAS3140), we have installed multipath-tools on this server and ensure that physical connection and swith configuration are correct, but we only can see a path? any advices will be appreciated.

:~ # multipath -ll

Please do not post your question in more than one location! That makes it hard for people to follow the discussion.

If you decide your question would be better served in another location, please use the REPORT button, and ask a moderator to move it for you.

I am going to have this thread closed, in favor of your other thread here: http://www.linuxquestions.org/questi...athing-781392/

Thanks.

Sasha
