we have two 2012 servers running SQL 2012 in an alwayson configuration which support our SharePoint farm.

We would  like to take a snapshot for them before making some troubleshooting changes and want to know what the best practice is.

I am assuming that we should shut them both down before taking the snapshot.

Assuming this is correct, how do I go about shutting them down gracefully and then bringing them back up?

Hmm. yes, I see.  Thank you.   I am not sure I would want to have to do a restore but backing it up first just in case is not a bad idea.

Perhaps I could shut down the entire farm, snapshot everything and then do my updates/troubleshooting/fixes.

I could then shut it all back down and either remove or revert the snapshots.  That might keep the timing issues at bay.

I would not want to run very long with a growing delta disk.

Do you have any instructions on shutting everything down?  (SQL 2012 in an always on configuration.)

I believe the right way is to do a "planned manual failover"

Turn off the secondary
Turn off the primary
snapshot
turn on the primary
turn on the secondary
go back to automatic

Disclaimer: This is all based on my limited research, there isn't much available and I've never done this personally.

Edit: you can also take an availability group offline, this might be better:

We have not done the snapshot yet but this is probably the way we will go.

I wanted to make sure you got your points .

Thanks, let us know how it goes. The way MS designed Always-On is so that it is ALWAYS on.
