Diagnosing a missing path to PGB
On an ES40 node $1$dga devices only have paths to PGA. On ES47 paths to both PGA and PGB are present. SHOW DEV FG/FULL displays WWID's on both controllers and no errors. Port lights are green (activity light flashing too) on both controllers and on switch. A SET PATH=PGB/ENABLE results in:
-SYSTEM-E-NOSUCHPATH, specified path does not exist
I suppose this could still be a hardware issue but are there any other online tests I can make before swaping the KGPSA? Zoning comes to mind but that looks correct and I can see both controllers from the switches.

Re: Diagnosing a missing path to PGB
I don't remember what the output of 'SHOW DEVICE FG/FULL' looks like, but I don't think it shows any controller or LUN WWNs. Have you checked on the EVA if the port WWN of ES40's PGB0 is assigned to the host entry?

Re: Diagnosing a missing path to PGB
When you created the host definitions there, did you see both WWIDs, one for each KGPSA?
Where those two wwids bnched into one host, or to two individually labeled hosts? In the latter case, was the Virtual Disk in question present both hosts?
Hein.

Re: Diagnosing a missing path to PGB
OpenVMS does not use Secure Path - it has multipathing embedded.

Re: Diagnosing a missing path to PGB
It was on the EVA side. I had in the back of my head that one of the KGPSA's was swapped out a few months back but didn't remember the EVA needs to know that (I last did that as part of the EVA "class" well over a year ago). I added the new host port on the EVA side, did SYSMAN IO AUTO and the PGB path was back.
Thanks a bunch!
