xsan/emulex config cookbook?

[gw1500se]

Can someone point me to an xsan cookbook. I am having no success with the xsan admin book. I have my xraid setup, I have my emulex in fabric mode on all ports. I installed xsan and started the admin client. That is where my success ended. The admin client cannot see any LUNs on the fibre channel. Although I suspect a problem with the emulex setup I can find nothing of any value for setting it up other then using the smart port fabric settings. TIA.

On your emulex, you should set all ports attached to storage as “Target with Stealth” and all ports attached to HBAs as “Initiator with Stealth”. If your emulex is actually a switch, you should be OK. Most emulex boxes aren’t actually true fabric, but act more like hubs (the 355 and 375). On those switches, you should set the HBAs on your clients manually to 2GB/Arbitrated loop. I don’t know much about the emulex siwtches that are actually fabirc, so i don’t know if you need to manually set speed/topology on those.

Thanks for the reply. It is difficult to diagnose this type thing when one doesn’t know what to expect. In any case your suggestion did not seem to help (I could find nothing in any of the documentation about it, how do you find this stuff out?). Is there something else I should be setting on the Emulex (355) other then the Smartports to what you said? What about the zone stuff? I’m pretty much clueless here with just the Apple and Emulex documentation.

If you connect the Xserve RAID directly to the host (ie. take the switch out of the equation), does it see it?

Even with the switch in the host sees, and has mounted, the Xraid. It is Xsan admin that does not see the LUNs.

Got it! The Xraid logical volume must be partitioned using Disk Utility ‘Free Space’ rather then the default ‘OS Mac Journaled (Extended)’.
