Series and the topic for today were Core Server Reliability and Patching Deep-dive.
The Webcast was recorded and is available online from the link above.
Patching is easier in Skype for business compared to Lync.
Here comes the QnA session, 6 questions and answers, enjoy!
Is a restart always required after patching a server?
No, a restart is not specifically required unless it is required by the updates themselves.
If a Front-end is rebooted after patching, is there still a need to use Invoke-CsComputerFailback?
Yes, a failback has to be done after a computer failover.
Can the failover/ failback commands be used with S4B on Windows 2008 R2?
Is there any noticeable difference for admins or end users if you have S4B running on an OS with Windows Fabric v2?
No, not to noticeable to admins, however, v3 has improved handling of network latency between other pool members.
Can you explain the difference in Invoke-CsComputerFailOver from Stop-CsWindowsService -graceful?
Invoke-CsComputerFailOver proactively moves the routing groups. It has the same "-graceful" behavior, but will not break quorum.
Should we patch one server at the time or multiple Front-end servers at the same time?
One at the time, but this is still much faster than in Lync Server 2013.
