False Disk Shelf mismatch error on Active/Active NetApp Filer

Message:

cf.fsm.shelfCount.fewerShelves:CRITICAL]: Disk shelf count mismatch: partner sees more of our A shelves on its B loop (14) than we do (13).

OnTap Version: 7.3.1

I got this bug while doing giveback of cluster, checked all the hardware and disks but they are working fine and there is no problem. Further checking in now site shown some light and I found a workaround for this.

Type the command 'options cf.takeover.on_disk_shelf_miscompare off'. This should be executed explicitly even if the option 'cf.takeover.on_disk_shelf_miscompare' value is already off

As of now there is no fix for this and NetApp has identified it as bug id 349449.
