Does anyone have any experience hooking these two together? I have tried everything I can think of -- but the Dell (Centos 6.7) can't see any of the LUNS. I am at the latest drivers from Emulex and Firmware -- the "hbacmd" has no issues seeing things.

I see hosts in the /sys/class/fc_hosts .. tried running various utilities like rescan-scsi-bus.sh and no errors -- but no new LUNS, etc. I see the device driver loaded, etc.

So no doubt there are some parameters / setting needed specifically to hook up to this HP SAN .. but I have NO clue what they could be.

Has anyone done this? !?!?

Haven't done this as we use RHEL with Qlogic rather than Emulex and our disk arrays have been EMC and later Hitachi VSP. At one point the HP arrays were OEMed Hitachi's but I don't know if that is so any more.

The reason I'm writing is your comment you can see the hosts but can't use them. Most disk arrays have a facility to map the disks (LUNs) you've created to specific servers much in the same way you do in your SAN Switch zoning. That is to say you often have to zone in your switch AND map the drives to specific hosts. If you zone the disk array to your server via a switch but do not also map the disks to your server within the array itself you'll see the array but won't be able to access the disks in such a setup. I'm thinking this may be your issue.

Thanks @MenaWater -- I have forwarded your idea to the SAN guys ... I'm just a lonely Linux guy who is just now dabbling on my first Linux -> SAN setup. Quite a learning experience !

By the way. CentOS6 is a binary compile of RHEL6 so the RHEL6 storage administration guide might be helpful for your CentOS6 setup:

OK -- the SAN guys fooled around with a bunch of settings and hooking it up directly to the SAN (bypassing the Fabric) -- and viola.. It all started to work just fine. I had to do nothing on the Linux side -- once the magic combination on the SAN was done, blam -- it started seeing all the LUNS and mapped them just fine. Go figured! Thanks everyone for the help though -- I learned a TON !
