Re: Configure failover in seconds

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

You can modify the isAlive and looksAlive timeouts, as well as the number of times to restart a resource, and the interval between restarts via cluadmin. Right click your disk resource, go to properties, then advanced.

Adjust the looksAlive and isAlive timeouts to suit your needs. You'll probably have to experiment to find the optimal settings since you don't want to ignore failed resources.

Good luck!

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.
