Since upgrading one of our storage servers to version 7 we are having problems with Vmware seeing the the target and volumes.
What we have noticed is that the fibre switch is showing that the port is in both modes (target/initiator), i have tried different ports and it is the same on the second FC switch as well. This is causing the problem with vmware because as soon as i plug a version 6 DSS server into the port it all works correctly.
So it seems that Version 7 of DSS does not advertise itself correctly.
Similar problem here with 10GBe cards connected to a 10GBe SFP switch.
The link status of the ethernet card and the switch shows up, but we cant get a ping through it.
With V6 on the same hardware it works perfectly
We are looking into this driver issue with the V7 and have the developers checking it out, we might need to get you another small update. Thanks for doing all the testing and verifying the network
Even though I have it working it is not as stable as DSSV6 was as we are getting some disconnection errors. I did raise a support call and mentioned the issue and I was told this was by design, really!!!! doesn't sound right. Why take a backward step and expect users to have to force fibre channel switch ports to certain settings. I am starting to think that we upgraded from DSSV6 that was working to DSSV7 that is less stable and worst of all we had to pay for this. I must admit that the interface is better in V7
Hang tight.... We found a similar issue on monday with a case, the support team is getting the developers involved to get some small update for the DSS V7. I placed a note on your ticket and the other case to run it up the ladder. I will have them reply to you when they get this small update ready.
Thanks todd,
hopefully it will be quick as these servers are in production and have our entire vm network in there, i am moving one of the servers back to V6 to get some stability

Ok I have managed to find out how to fix this, it appears that with DSSV7 the switches are not seeing the qlogic fibre cards as qlogic cards. So I had to disable the I/O Streamguard on the ports of the fc switch that the servers where plugged into. Now I can see all the volumes and targets with the vmware servers
