Then the output of multipath is imho indeed right. For me it shows the setup you've described - one raidgroup, shared via 2 LUNs (usually one per default on SP A, one on SP B, attached via 2 paths per SP to a switch, accessed from your server via 2 HBAs. If you have access to the Navisphere cli tool - please post the output of ./navicli -h IP_OF_ONE_OF_YOUR_SPs getlun I think this will show that my hint is right. Imho you want to create a second raid group and share it via 2 LUNs, too. </pre> <blockquote type="cite"> <pre wrap=""><a class="moz-txt-link-freetext" href="http://christophe.varoqui.free.fr/wiki/wakka.php?wiki=TestedEnvironments">http://christophe.varoqui.free.fr/wiki/wakka.php?wiki=TestedEnvironments</a> </pre> </blockquote> <pre wrap="">I hope there's nothing wring with the stuff I've written about the EMC/CX in there, if you find anything please let me know - I don't look in there often.
