Description

This article describe one known issue when setting up a new High Availability Pair.

After configuring the HA on the primary firewall as per How to Configure High Availability (HA), the Primary firewall will show the message "Error Contacting Peer HA Firewall" ; "Cannot force failover: Peer's link status is worse than us"

Cause

This error might be related to one of the following:

Version mismatched, both firewall Firewall doesn't have the same Firmware version.
You have a cabling issue. This means the standbys unit has less links that are up than the primary; Meaning: your standy unit has an interface that is down, but on the primary it's up.
Portshield enabled on the Secondary (Peer) Firewall's interfaces
Administration Password is not the default one or is not the same on both firewalls.

Resolution

Resolution for SonicOS 7.X

This release includes significant user interface changes and many new features that are different from the SonicOS 6.5 and earlier firmware. The below resolution is for customers using SonicOS 7.X firmware.

Check the current SonicWall firewall firmware version

Login to the SonicWall Management interface.
Navigate to the Dashboard.
Go to Overview | Device | General
You will able to see the firmware version under General

Check the Portshield status on the Secondary (Peer) firewall's interfaces: How to disable Portshield
On the Primary firewall, change the Administration Password to the default one:
1. Navigate to the Device Tab.
2. Go to Settings| Administration Settings and scroll down to Administrator Name & Password
3. Set a new password for the Administration that is identical to the Secondary administration password.
  CAUTION: It's highly suggested to use the default password since we assume the secondary is on factory default and so it's set to the default password as well.

After doing this, if everything is properly set up (control interface properly connected, serial numbers correct on HA configuration, and port shield disabled on the Secondary), the HA should start the process of synchronizing the configuration.

The Administration Password can be, of course, changed back to a custom one after the HA Pair is correctly synchronized.

Resolution for SonicOS 6.5

This release includes significant user interface changes and many new features that are different from the SonicOS 6.2 and earlier firmware. The below resolution is for customers using SonicOS 6.5 firmware.
