  • During the upgrade to 11.7 a storage node goes into an unknown state and the upgrade.log on the appliance is failing with the below Error:

Upgrade.log:

  • Can see network isolation events from the remaining nodes when they attempt to communicate with the affected one. 

dynip.log

WARNING -- Possible network isolation: Node has no contact with other nodes. If this warning persists, use the /usr/sbin/add_node_ip.py command to tell this node the address of another node in the grid. See the Recovery and Maintenance Guide for details.

  • The Storage node cannot connect to any GRID node on any GRID port and the IP of the affected node is missing from the element grid_ips in nft ruleset. Checked by running the below command:
