We have an IBM SAN DS4500 connected to two hosts IBM eSeries MXE460 (eight nodes) via Fiber Channel and two Brocade Switches. We believe that our SAN system is configured properly, we can create Arrays, LUNs and Zoning are online. But somehow when we present the storage to the VMWare host (ESXi 4), nothing is showing up in VSphere (after running multiple time "Rescan All" on all HBAs). Also, we believe that we provided the right WWN from the Brocade Switches, we retrieved the WWN when we created the Zone.
Now, I would like to know if someone can tell me how to check if the HBAs are communicating properly between the SAN, Brocade Switches AND the VMWare Hosts (MXE 460). I tried so many things, but don't know what to do now - if someone can give me some hints then this would be GREAT!
If you need further details, please let me know.
Please don't ask me to place a call with IBM, this would be the last resort.
