Hi all,
Currently we're running everything on C: but I've convinced management to split out, what's the command to add drives ?
Thanks guys

We're adding drives to the database server. 🙂

A better question is, "What is the best procedure to move database system and user databases to new drives?"

That would be a far better question, because there's no SQL command to add drives to a server. 😉

Firstly, you don't want to move the binaries, as that would require a reinstall of SQL. To move database files, ALTER DATABASE ... MODIFY FILE, then take the DB offline, move the files (via Windows Explorer), bring the DB back online

Was always going to let the binaries stay put on C:\, I think MS still recommend they reside on the same drive as the OS.

Couple of further questions please....

Should the system databases be best moved in any particular order?

Any objection however to scripting out the file move part?

To be honest, other than TempDB, I'd probably leave the others alone for now. Moving master is not the same as moving other databases, model and MSDB are also slightly more involved

Scripting with what? SQL can't do the file moves.

I hear you. According to MS it's straightforward 🙂

DOS, there are gonna be quite a few destination folders.

--edit - dumb question, disregard 🙂

CMDShell, there are gonna be quite a few destination folders.

That won't work because the server will be active to use it, which means that the files will be locked by SQL Server and won't be able to be moved.

Not if he's taken the user databases offline, SQL does not need to be shut down to move user databases around.

Understood and absolutely agreed. I was talking about the system databases, which seemed to be the concern for moving.
