Configure mirroring for CentralMgmt database (xds and lis)

Hi all,

Seems like CentralMgmt doesnt have any mirroring enabled,since i can only see xds and lis on the primary backend server.

What is the correct way to enable mirroring for these databases and is it safe to do during work hour?

You can use "Install-CsMirrorDatabase" cmdlet as described in this article: https://technet.microsoft.com/en-us/library/jj204992(v=ocs.15).aspx and use -DatabaseType switch to add the missing databases (CentralMgmt for example). As usual, outside of working hours is always preferred :-)

Hi Drago and thanks for tips.

My issue is that when i run get-csdatabasemirrorstate -poolfqdn lyncfepool01.domainlocal i see that xds and lis doesnt have Mirror.

If i run Install-CsMirrorDatabase -SqlServerFqdn lyncsql11.domain.local DatabaseType CentralMgmt -FileShare \\lyncdfs01.domain.local\LyncFileStore\ i get error No databases were found for mirroring or witness setup.

Ideas?

thanks!

This is strange. I just broke the mirror for xds in my lab and the command promptly executed and created it. I assume lyncsql11.domain.local in your command is the primary back end for the pool?

If so, I suggest open a case with Microsoft Support.

Hi,

have now updated with CU11 and run Install-CsDatabase CentralManagementDatabase SqlServerFqdn  lyncsql11.domain.local  SqlInstanceName RTC Verbose.

then ran : Install-CsMirrorDatabase -SqlServerFqdn lyncsql11.domain.local DatabaseType CentralMgmt -FileShare \\lyncdfs01.domain.local\LyncFileStore\ i get error No databases were found for mirroring or witness setup.

So i have same issue.How can i re-build the cms database so it creates a mirror?

thanks!

Managed to fix this.Seems like the error was that i was pointing to Lync fileshare,but should instead point to Lyncmirroring (mirroring used between SQL/backend servers).

Now all is ok and Centralmngt is mirrored.

thanks!
