I am involved in moving some servers to different zone within the same data-center. There are no IP changes, so I would think this is the same as normal server shutdown. The server will be out for more than 24 hours.

In terms of DBA perspective, I was thinking about stopping the SQL services before they shutdown windows box, and start the SQL services after server up and running.

Anyone have any other suggestions? Also, from app server side, do they need to be shutdown as well? If you had similar experience, or if you know the actual steps, please share.

Thanks in advance,
SueTons.

This will work just fine.

Down for 24+ hours??? Wow...that's a LONG outage!

Thanks for your reply, do you know if the app server need to be shutdown as well? or not necessary?
or it just requires a reboot after windows box and SQL services are up and running?

It Depends. If the app servers are going to be looking to the SQL Server for a connection you may want to put of a "sitedown" page to let users know the site/application will be unavailable

Isn't it better for the web server to be shutdown also? Since it will be more than 24 hour?

If the web server doesn't serve any other purpose, then there should be no issues with it - good luck!

What you mean if web server doesn't serve any other purpose? Isn't it apps connecting through web servers, if you have a better understanding, please explain.

If these servers have mirroring in place, when the principal server shuts down, do I need to shutdown the mirror server(DR) as well? Or it's okay to leave mirror server up and it will stay as stand-by?

Re: Web Server: a web server can be used for anything and not necessarily SQL-related applications, so the reason I even mentioned this was for you to check to make certain nothing else is using the web server before you shut it down for a day.

EDIT :: Mirroring - from what I've read you should be okay with this, but I would make sure you verify the steps for rolling over to your DR server just to be sure (I'm not overly strong on mirroring)
