on my 7-mode lab system i got this message: BGNA108061:monitor.shelf.warning:warning]: Fault reported on disk storage shelf attached to channel 0a. Check fans, power supplies, disks, and temperature sensors
THIS SHOULD NOT BE APPLIED OR TESTED IN PROD SYSTEMS - CONTACT NETAPP SUPPORT SO THEY CAN GIVE YOU ACCURATE AND SAFE GUIDELINES. THIS CAN TECHNICALLY BRICK YOUR HARDWARE - SO YOU BETTER JUST LEAVE THE WARNING ALONE (the warning usually doesn't cause actual harm).
Now that the disclaimer is done
If you have another few working shelves from the same model and firmware versions, you can see in the other ones which one of the VPD lines is correct, using sasadmin expander_cli <HBA port.shelf ID> 'vpd 16' (and 17). copy it to notepad or use grep if running from linux to look for line 0180 (as your mismatch shows).
if you see o all of them showing the same value, it's should be OK to copy the correct VPD on your shelf to the corrupted one on the same shelf.
I don't have the expander_cli commands in hand to copy, but i'd assume you can type help, ? or leave blank and it will list the commands....
Again, NetApp support could provide better advice and not do it in this way, they have a dedicated description for each line in the VPD, the expected values and guidelines what can be copied (most of the corrupted lines) and what not (lines contain serial numbers, incorrect shelf IDs etc).
Unfortunately we are unable to assist with this, as the system is out of support, and the support process includes obtaining logs, running the case number with the logs through an internal tool, or manually consulting with engineering, and if the system is not under support, those are not options.
Turning the system and shelves off, entirely, leaving it for 5 minutes and turning it all on again may clear the error. Otherwise, turning it off, moving the disks and IOMs across to another shelf would be an option, as the error is on the backplane, not the IOMs or drives.
As @GidonMarcus says, the data can be copied from a "good" shelf, but understanding what "good" is and what is a viable shelf to copy it from is not a clear question, even for us. I've done some crazy things, but I wouldn't be doing this without support guidance. I cannot stress this enough to anyone else finding this post, but contact support for assistance, do not try to fix it with these instructions with the view to contacting support if it doesn't work.
