Synchronization Tab
The Synchronization Tab provides commands for these options:
• Changing the synchronization state of the system (synchronize or
disqualify)
• Initiating a switchover
• Forcing the disqualified secondary to become the primary
The commands available are described in the Commands in the Synchronization
Tab section on page 117.
This tab also provides information about the last four synchronization attempts
in the Recent Synchronization Attempts log. Attempts are identified by N or N-
X. If the redundant chassis fail to synchronize, a cause is identified in the Recent
Synchronization Attempts log.
The causes and their interpretations are described in the Recent Synchronization
Attempts Log section on page 118.
