FAS6030 comes up on previous version of Data ONTAP after a NDU

After doing an Non-Disruptive Upgrade (NDU) on a clustered filer, it may come

up in the previous version of Data ONTAP after the system reboot.



Workaround


1) download new kernel on node1

2) do 'cf takeover' on node2. node1 will do a shutdown and reboot.

3) Reboot node1, it will go to 'Waiting for Giveback'. Check the console and determine if it booted on the correct kernel. If it did, proceed to step#7

4) Press Ctrl-C and go to the Maintenance Menu

5) Halt

6) At the loader, type boot_primary

7) At this point, the node should be booted on the correct release and be at 'Waiting for Giveback'

8) On node2, do 'cf giveback'

9) node1 will complete booting.


Note! This can also happen on a FAS3070
