Daniel, What happened with your VM problems?
Which config failed? The one that you got working, or the new one when you tried to replicate? Which version of linux are you using? >From this linux log, I only see one thing that is interesting " fsf_prot_status 0x00000080". This is connection initializing. There are 3 ways to get this: 1. The fibre channel link is not up. If you look at the SE, you should see online operating when the link is up. Did someone unplug the fibre from the channel? Are the optics in your channel, the switch, and the fibre consistent? Either all short wave, or all long wave. Is the switch trying to run at a speed that the channel doesn't support? 2. Are you issuing lots of chccwdev --online, chccwdev --offline, chccwdev --online, .... We'll send this status up if the QDIO and FSF parts of the channel get out of sync. QDIO quickly initializes. FSF doesn't because it has to communicate with the switch, and this status is a way to tell the operating system to be patient. 3. Very similar to 2... We're waiting on FDISC reply from the switch. Are there any clues on the fabric login status panel on the SE? Have you seen this redpaper? http://www.redbooks.ibm.com/redpapers/pdfs/redp4125.pdf It has some details about the SE panels. I hope this helps.

Port security has been toggled, WWPNs have been added and removed from the zone. This is becoming incredibly frustrating. If anyone can provide any answers..

If it only reports the one you had attached, it doesn't sound like the switch zones are setup properly to let the LPAR see the DASD subsystems. Has the SAN admin registered the physical WWPN of the card with the switch zone, or the NPIV WWPNs (displayed on Q FCP output)? The latter is necessary in NPIV environment.

That particular output was from a different device (i.e. 5001).. my terminology is a little off. Our SAN admin swears it's configured correctly on the switch.

Are there other WWPNs listed in the SCSIDISC output beyond what you have sent? If so, what does SCSIDISC see with them? If not, has the switch been told about the NPIV WWPNs that the VM LPAR will be using (that is, those listed in Q FCP)? What specific messages do you get when varying on the EDEV? One other thing... the FCP subchannel (5000 in your example below) shouldn't be attached to a particular user if it is going to be used as part of an EDEV. It should be free so that VM can attach it to the SYSTEM itself at the time the EDEV is varied online. (The FCP can be used for multiple paths/LUNs at once, so in reality the FCP should be either free or attached to SYSTEM.) The ATTACH 5000 TO * command would be used for a guest to use, such as for SCSIDISC or Linux itself configuring SCSI.

I only know basic commands and concepts, but really need to get this working. Our san is connected, and other LPARs can see the storage. the CHPID is online. I can attach the storage (ATTACH 5000 to *) and SET EDEV blahblahbah.. but when i try to vary on the storage,i get a NO PATH TO DEVICE error. Anyone have any ideas?
