These release notes describe the following topics:
Obtaining Technical Assistance
These release notes are to be used in conjunction with the Cisco LocalDirector Configuration and Command Reference Guide, Version 4.2.
This section describes the new LocalDirector Failover enhancement in LocalDirector Version 4.2.2.
The LocalDirector failover feature now enables an active unit in a LocalDirector failover pair to automatically detect recovered communication of a failed interface on the partner unit, and then request the failed partner unit to switch to standby mode. Thus, you no longer have to issue the failover reset or failover active commands to manually restore a failed primary LocalDirector.
With this enhancement, interfaces continue to function on a failed LocalDirector. This allows the failed LocalDirector to continue attempting to send hello packets on each interface and discern if an interface has re-established communication with the partner.
If an interface on a failed unit has re-established communication with the active unit, then the active unit recognizes the failed interface as operational. If all interfaces and the failover cable are considered to be operational by the active unit, then the active unit sends a message over the failover cable causing the failed unit to switch to standby mode.
The following syslog message indicates if communication for a specific interface is working:
Unit: Monitoring on interface 1 normal
The following syslog message indicates when the active unit is sending a message over the failover cable to the partner and causes the partner to switch to standby mode:
Unit: Hello communication resumed for all interfaces, resetting partner
|
Note Unit can be Primary or Secondary, depending on whether it is the primary or secondary unit as determined by the failover cable. |
