To perform the BackupPool failover open Skype for Business Server Management Shell on backup pool.
In my setup, I have Se01.uc.lab and Se02.uc.lab.
Now I am performing pool failover as my first server “Se01.uc.lab” is down.
Go to the Se02.uc.lab and open management shell.
Run “Invoke-CsManagementServerFailover –BackupSqlServerFqdn <backuppoolfqdn> -BackupSqlInstanceName rtc -Force
After CentralManagement failover, you can verify the status.
Run “Get-CsManagementStoreReplicationStatus –CentralManagementStoreStatus”
It will show the new active central management server in my setup “Se02.uc.lab”
Now, you can invoke the pool failover.
“Invoke-CsPoolFailover –PoolFqdn <primary pool fqdn> -DisasterMode –Verbose”
After finishing the failover process you can verify the same from topology builder as well. Now you can Se02.uc.lab is active Central Management Store.
Pool Failback:
Follow the below steps for failback process.
Once you Primary Pool comes up open Skype for Business Server Management Shell
Run “Get-CsService –CentralManagement” to get the current status. Now you can see below, Central Management “Active” status is showing False in primary server while backup/secondary server is True.
Now perform the failback process.
Run “Invoke-CsPoolFailBack –PoolFqdn <Primary Server Fqdn> -Verbose
Now perform the central management failover to primary server or you can leave the central management on backup server.
To perform failover run “Invoke-CsManagementServerFailover –BackupSqlServerFqdn <primary server fqdn> -BackupSqlInstanceName rtc -Force
Once you are done with the failback you can verify the same.
Run “Get-CsManagementStoreReplicationStatus –CentralManagementStoreStatus”
You can verify the same from topology builder as well.
