Merge Failure Troubleshooting
Recovering from a Merge Failure with Fabric Manager
To recover from a merge failure using Fabric Manager, follow these steps:
Step 1 Select the CFS tab for the application that you are configuring and check the merge field to identify a
switch that shows a merge failure. For example, choose Fabricxx > All VSANS > DPVM and select the
CFS tab to determine if there is a merge failure for DPVM.
Step 2 Set the Config Action drop-down menu to commit and click Apply Changes to restore all peers in the
fabric to the same configuration database.
Recovering from a Merge Failure with the CLI
To recover from a merge failure using the CLI, follow these steps:
Step 1 To identify a switch that shows a merge failure, issue the show cfs merge status name application-name
command. Example command output follows:
Switch# show cfs merge status name ntp
Physical Merge Status:Failure [ Mon Nov 22 06:49:52 2004 ]
Failure Reason: Conflicting entries in the compared databases
