Ok, here is the real answer: you can not.

When a failover starts, it starts. There is no parameter where you can set a
"pause" because of your san disks who need to failover.

What you can do however is to create a "scripted geo-cluster"

1) script your "failover commands"
2) add this script as a resource to your cluster
3) make your disk resources dependent on your script

this way, on failover, your script fires on node 2 first, your disks are not
failed over in the san / still at node 1, but your script takes care of
this, and your disk resources do not come online until your script finishes.

script finish / online --> disks on san are failed over --> physical disk
resources come online properly

and please see this blog (
http://msmvps.com/blogs/jtoner/archive/2007/05.aspx ) from John Toner on
this subject, it details how you do this on an EMC Clariion, but you
probably can apply methods to your specific environment.

Please realize, if you do all this, you are NOT using a qualified solution,
I am afraid you are running a NON-supported solution.

I would never run production applications on such a scripted geo-cluster.
Because I can think of many, many scenarios where your script would not
execute or not pick up the exact conditions to determine the correct action.
Also a scripted geo-cluster will have a risk of a split brain due to not
picking up the correct information, or not having the logic to deal with the
situation/failure.

Testing with this in a test/lab environment, sure ! I have done it, good fun
!

rgds,
Edwin.

Guys, all I want to "please" know is where do you set the number of
seconds
to wait before failover occurs from one node to another in Windows Server
2003? Is this done in CLuster Administrator? If so, where do I set this
property?

Thank you.

are you using for this ?

I want to change the number of seconds MSCS failover occurs so it does
not
conflict with SAN failover.

Thank you.

I want to set a property in Cluster Administrator: number of
seconds to
wait
before failover occurs from one node to another in Windows Server
2003.

Thank you.

To set the value of the ClusSvcHeartbeatTimeout property, run the
following
command from a command prompt:

cluster.exe /cluster:clustername /prop
clussvcheartbeattimeout=number
of
seconds

where clustername is the name of the cluster and number of
seconds is
the
number of seconds that you want to use in the calculation of the
heartbeat.

But, I would not mess with it. What are you trying to accomplish.
