Hi, >>I'm trying to configure a new emc cx storage, I have the following: >> >> >>I defined two lun on the storage however I'm able to see only one LUN >> >>multipath -l show the following: >> >>multipath -l >>mail (36006016086f01600e46f567adb8cda11) >>[size=150 GB][features="1 queue_if_no_path"][hwhandler="1 emc"] >>\_ round-robin 0 [active] >> \_ 1:0:1:0 sdd 8:48 [active][ready] >> \_ 1:0:1:1 sde 8:64 [active][ready] >> \_ 2:0:1:0 sdh 8:112 [active][ready] >> \_ 2:0:1:1 sdi 8:128 [active][ready] >>\_ round-robin 0 [enabled] >> \_ 2:0:0:0 sdf 8:80 [active][ready] >> \_ 1:0:0:0 sdb 8:16 [active][ready] >> \_ 1:0:0:1 sdc 8:32 [active][ready] >> \_ 2:0:0:1 sdg 8:96 [active][ready] >> >> >> did you probably just share one raid group via 2 LUNs? 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. >http://christophe.varoqui.free.fr/wiki/wakka.php?wiki=TestedEnvironments > > 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.
