Note the following:

• If a node in the appliance is factory reset or reimaged, the version-specific hotfix must be applied on that node immediately after it is added back to the appliance and updated to the appliance.
• If an appliance is upgraded to any of the versions mentioned in the previous table, the version-specific hotfix must be applied on all nodes in the appliance after you commit the upgrade.

Special Note for Flex 2.1 relating to Air Gap 

In the case of appliance recovery, first install the 2.1 hotfix (which has IRE Air Gap capability) and then start WORM storage server instances to retain the filtering rules that were in effect before the factory reset or the reimage.
