[Xen-users] SR Creation

["James Alspach" <jalspach@xxxxxxxxxxxxx>]

About a month ago I ran some initial tests of iSCSI SR’s in XenSource.  As a new user I wanted to learn how to set them up and how they worked.  That all went great.  Now I am trying to set up our production environment and am running into problems. 

It turns out that when I tested I used the software initiator and not the HBA’s.  The instruction I found said to use lvmoiscsi but now I see that I should have used lvmohba since we are using QLogic iSCSI HBA’s. I discovered this because, after these tests, we moved all of the HBA’s onto a separate VLAN and set up jumbo frames.  Therefore, when I attempted to connect the old way (lvmoiscsi) it did not work, obviously I was on the wrong network and the network I was on did not support jumbo frames.

 

Now when I go to the command line and run:

xe sr-probe type=lvmohba device-config:target=10.1.4.100

I get a more or less empty dev list. All that is returned is the host, name, manufacturer and id.  I do not get any other info. 

What am I missing?

 

I can ping the iSCSI host using the tools in the QLogic software but only up to a packet size of somewhere over 1450; 1475 and above fails. This makes me think that the MTU on the VLAN is set wrong which I am looking into now. 

 

Are there any other checks I should do to narrow this down?

 

Thanks;

James
