Shelf ID showing as 204 (instead of the assigned 12).

Hello, 

 

I just recently had NetApp Support replace a damaged IOM for the B side on a 224C disk shelf and after plugging in cables, one of the nodes (on a 2 node cluster) shows a shelf ID of 204 (when it's supposed to be 12). Anyone seen this before? System is cabled correctly physically and only 1 nodes shows it incorrect, not the other. Config Advisor came back clean and 'sysconfig' shows Multi-Path HA for both nodes. Very weird. 

 

As shown on the incorrect node...

I would also verify with support.   They have had me to do takeover/givebacks as part of troubleshooting quirky shelf issues.

I have seen some odd stuff with shelves before.  But what's support say?  Have they had to try to re-seat the IOM or do a take-over?    How's the firmware look?  is it current or stuck updating?

That's bizarre. I wonder if something else is still wrong. Definitely have our HW folks look. From my initial glance I don't know why this would happen but something is definitely off.

 

If it's just cosmetic it should function just fine.

Thanks for all the insight! I have tried reseating the IOM, but only for about 10 seconds. Have not done a takeover/giveback. I would need to schedule an MX for that since we have customer data on that array.
