It looks like you are not getting logged into the fabric (which you should be able to check from the SE Fabric Login Status page) (see page 19 http://www.redbooks.ibm.com/redpapers/pdfs/redp4125.pdf ) If you aren't, switch log reviews may be the next step. FWIW, i have the exact same messages after weekend fabric work here and we are failing to login. VM Support has said the -62 is outside of vm. The last time we struggled here it was the domain in the switch. We have the added wrinkle of having channel extension equip in the middle now.

Based on prior email, C05076FAE3000400 is the WWPN of your virtual FCP adapter (because NPIV is in place). It starts with a "C". But 50060E80042CC20C looks to me more like a storage side WWPN. What is the "real WWPN" of your FCP adapter 5000? Might start with "5005", though a "5006" prefix is certainly also possible. (Someone who knows FCP better than I might know vendor prefixes and things like that.) When you had Linux up (instead of CMS), what did you find in these pseudo files? /sys/bus/ccw/devices/0.0.5000/physical_wwpn /sys/bus/ccw/devices/0.0.5000/wwpn The latter should be 0xc05076fae3000400. What is the other? (If you did not have NPIV in effect, then the two would match or one be zeros.) Since you said that you have it working on one or two other systems, how to they look by comparison? For zoning and masking and all that, it is not clear to me that you need to specify the real WWPN (of the HBA, of the FCP adapter) when NPIV is in play. Eric? What do you say about that? You certainly DO need to zone and mask the storage and the fabric to the virtual WWPN (the one with the "C050" prefix). -- Rick; <>< On Tue, Apr 20, 2010 at 09:13, Daniel Tate <daniel.t...@gmail.com> wrote: To answer someone's earlier question, yes, we've seen every redbook imaginable related to this, tried to do a direct zfcp attach, set edev. I can't give too much info away about our organization but we are using cisco san switches, if that makes a difference. Both the perm and the virtual WWPNs are in our zone. Port security has been toggled off then on, the entire CHPID has been toggled as well. NPIV is on everywhere, NPV is off. Another earlier question was were we doing a lot of attaches/detaches, and the answer is yes. unfortunately its not easy to read this debug information - at times i've had to go to the source code of the zfcp driver to make an educated guess at what the "perr" and "ferr" codes were with codes 0x0d and 0x05 (thanks to the person who clarified those).

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.

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.
