I can see and write only on the LUN called mail, I'm not able to see ql

thanks for your help,

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

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.

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.


Hope that helps,

best regards


Bernd
