#Skype4B – Backup Pool Failover and Failback : PartII


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.
