Symptoms:
- You have updated NSX-T from 2.3 to 2.4 or above some time in the past and have had other subsequent upgrades.
- You use a weak passphrase, that is one which is less that 8 characters, no numbers, no upper case or special characters.
- If you need to restore the backup taken with a weak passphrase, this fails with passphrase error:
Restore process failed. 'Cluster' restore failure, possibly, due to a bad passphrase
- In the NSX-T manager /var/log/syslog you can see the following error:
