Hi All
I attempted upgrading SRX340 in a cluster from version 15.1X49-D40.6 to version 21.2R3.8 but encounter an error below while upgrading.
WARNING: Not enabled dual root partition on secondary node
ISSU not allowed
I applied the command ''request system snapshot slice alternate all-members'' but still got the same error.
The upgrade Path to 21.2R3 is as follows
==================
First Hop upgrade to - 19.4R3
Second hop upgrade to - 20.4R3
Third and final upgrade to 21.2R3
Has anyone see this error and managed to resolve it?
Thanks
