Hi Vipul


- utils diagnose test

Command not exist

Cluster Manager may be in a bad state.

Use the command 'utils service restart' to restart Cluster Manager

  • Cisco Employee,

utils dbreplication clusterreset all command should follow by cluster reboot.


if you dn want to reboot the cluster, you run the command


utils dbreplication reset all


thanks,

Dear Vipul


I opened a case in Cisco TAC. Took the case your coworker John-Paul.

Yesterday at night,  I performed a reboot the cluster and then, all servers have a replication count of 348 and all servers have a good replication status.

The customer wants to know why this problem occurred. Please, if you have an idea, could you tell me what are the reasons that could cause this problem?.


TIA.


Cristian
