Is this the correct command line syntax to put cluster "DAG-TEST" back online after it has mysteriously gone offline for 60 seconds?

C:\Cluster /cluster:DAG-TEST  /on:domain_name   /wait:60

Yes your syntax does look correct but have you checked the event logs or Cluster log to see why the resource keeps going offline in the first place?

Yes, we have 2 Exchange server in the DAG and they are across a 10 mile WAN link from each other. Occasionally they lose communications with each other and that breaks the DAG.

When I attempt to run the following command but substituting the actual domain name
C:\Cluster /cluster:DAG-TEST  /on:domain_name   /wait:60
I get the error: Invalid option 'on'.
Also the Cluster cmd does not have an "/on" option.

has anything changed on your network recently?
What is the latancy between sites?
I presume the proper DNS enteries are in place for you domain?

As a test try this:

C:\Cluster /cluster:DAG-TEST  /on:node1   /wait:60
C:\Cluster /cluster:DAG-TEST  /on:node2   /wait:60

Q1:has anything changed on your network recently?
A1: Not that I am aware of.

Q2:What is the latancy between sites?
A2: When I ping the DAG IP which is across the WAN link, it's 2ms or less response time.

Q3:I presume the proper DNS enteries are in place for you domain?
A3: Yes they are.

Q4: As a test try this: C:\Cluster /cluster:DAG-TEST  /on:node1   /wait:60
A4: The syntax is the problem, open a cmd prompt on a system where you have installed
       MS Failover Cluster manager. Type Cluster /?; the "/on" and "/wait" options are not
       valid options.

Q5: I need to know the "correct" syntax, if any exist to bring a cluster online using the command prompt.

Oh wait a second...

I you may be missing resource group name.

Try something like this:

C:\Cluster /cluster:DAG-TEST  /group ResourceGroupName /on:Node1 /wait:60

Ok, you may be on to something here. I'm able to cluster status using the group name. Will try bringing the cluster online the next it goes offline. Will let you know what happens.

Sorry for being slow to respond, but so far, my DAG cluster has not gone off-line to test the command.

Cluster /cluster:DAG-TEST  /group ResourceGroupName /on:Node1 /wait:60
This command is close to the resolution, I replaced "/on:Node1" with "/online:Node1". However since my DAG has not gone off-line lately I have not been able to test using this command.
