How I can create Exchange DAG without witness server? Classic cluster can assign LUN for qourum.

Please help.

Just use a file and print server or something like that for your FSW.

Can I create DAG without any additional server (file/print)? just add a LUN in a cluster?

I know of no way to create a DAG without a witness server.

Maybe you have a link to the technet article?

I know of no TechNet article documenting my lack of knowledge of how to create a DAG without a witness server.

you can create a dag with an odd number of members and the file share witness won't be used, BUT as Ed said,you will still need to specify a file share witness when you create the DAG.

Also, comparing to a DAG to a normal cluster is like comparing oranges and lemons.  sure they are both citrus fruits, but they are completely different.

You must have a domain controller, no? But in that case, you need to add "Exchange Trusted Subsystem" into Domain\administrators group...

It's my experience that you can't create the DAG without the witness server.  When you have an odd number of nodes, the witness server won't be used, but it has to be there.

Thanks
