4. Perform Steps 1 to 3 on the other Equalizer in the failover pair.
Upgrading Failover Configurations from Versions prior to 7.2.1
The upgrade script contains facilities to migrate a version 7.1 format failover configuration (stored
in /etc/eq.static) to the new format used in 7.2 and later systems.
When the upgrade script runs, it will detect the presence of a valid configuration in the eq.static file.
If it finds this file, the script prompts you whether to migrate the failover configuration.
If you respond ‘y’ to the upgrade script’s prompt, the configuration file will be migrated to the
upgrade partition, and the following message displayed:
IMPORTANT NOTE: configuration file transfers will be disabled when the
system reboots. You may re-enable configuration sharing by clearing
the dont transfer checkbox in the equalizer global parameters page.
If you are configuring failover between two different types of
Equalizers, where one contains a built-in switch and the other does
not, configuration file transfers must remain disabled between the two
systems. (See release notes)
This indicates that when the system reboots, the dont transfer flag is set and any changes that are
made to the configuration of this system will not be shared with the failover peer. You may clear the
dont transfer flag once the system reboots, provided the failover pair is not both operating in single
network mode and a combination of a switch-integrated system with a non-switch system. See
“Using Failover with Different Equalizer Models or Versions” on page 51 for more information.
Changing the Network Mode between Single and Dual
It is important to delete the failover configuration before changing the network mode between single
and dual network on an Equalizer that is already configured for failover. If the network mode is
changed before the failover configuration is deleted, the web browser interface will become
unusable because the configuration parser generates error messages stating that the failover
configuration does not match the network mode.
Troubleshooting Changes between Network Modes without Deleting
Failover Configurations First
The following manual procedure deletes the failover configuration and should only be used if the
network mode was changed without first deleting the failover configuration. You should follow this
procedure with the assistance of a member of Coyote Point’s technical support team.
1. Log into the Equalizer via SSH using the eqsupport account or as root via the serial port.
2. # mount –w / (if using the eqsupport account, you must use su first)
3. Edit the file to remove the interface stanza and save it.
# ee /var/eq/eq.conf (vi may be used as well)
4. # shadow /var/eq/eq.conf
5. # shutdown -r now
This command reboots Equalizer.
