Release Notes
55
• [Ref. #24597] If an Application Server (whose iControl services are initially online) is added to
an existing redundancy group in the role of Backup, the iControl services of this new
Backup Application Server continue to run after the server has been added to the group.
Workaround: Before adding an Application Server to a redundancy group as a Backup,
make sure you stop iControl services first.
•
[Ref. #24199] Connection to a Backup Application Server may be lost if either of the
following is true:
• The configured IP address, in the Redundancy Configuration Form’s Extra IP field, is
outside the group’s subnet.
OR,
• There is no configured IP address in the Redundancy Configuration Form’s Extra IP
field, and the factory default IP address is outside the group’s subnet.
Workaround: Disconnect and then reconnect the Backup from the network.
•
[Ref. #23834] When a user connects a device to the network with the same IP address as one
of the Main Application Servers in Auto-failover mode, the Main could become
Yellow/Unknown and a failover could be triggered.
•
[Ref. #23639] Backup Application Server keeps Main’s host name after a reverse takeover if
not taking Main’s IP address.
Workaround: Change host name on Backup Application Server back to Backup host
name.
•
[Ref. #23624] Cluster synchronization problem when replacing a Main Application Server
after a failover without taking the Main’s IP address.
Workaround: The documented procedure (Replacing an Application Server in a
Redundancy Group) in the iControl User's Guide outlines the appropriate steps you should
take depending on whether you have chosen to have the Backup take the Main's IP address
or not.
•
[Ref. #23470] After a failover, the backup files listed on the iControl Backup page of the
Application Server that is now online are the backup files of the configured Backup and
not the configured Main. The backup files on the newly online Application Server should
be from the configured Main.
Workaround: Perform a Reverse Takeover. After a Reverse Takeover, the Main’s backup files
are available on the Main Application Server and the Backup Application Server’s backup
files are on the Backup Application Server.
•
[Ref. #23402] After a takeover, the cluster goes into Manual mode and does not
automatically re-enable the Autofailover function after a reverse takeover is performed.
Workaround: Log on to the configured Backup Application Server’s Webmin, navigate to
the Redundancy Configuration Form, manually re-enable the Autofailover function for all
Main Application Servers, and then click Apply.
