Changing SCSI Bus sharing mode from Physical to None

I need to make some configuration changes on one of the SCSI controller which has got 12 RDM attached into the Guest OS (Windows server 2003).

Does that cause any outage or drive letter change to the Operating system ?
what is the impact caused by doing this ?

Thanks.

Thanks for the reply,

in this case I cannot make any backup because the backup software failed to take snapshot of this VM (File Server).
You may want to check why, you cannot backup, RDM LUNs, could be the issue.
It is, but my concerns is about changing the scsi bus sharing type only ?

Downtime is fine for me, but what happened after I changed the scsi bus type ?

If you don't mine me asking what is causing you to change you SCSI mode?  have you check to make sure the mode you are changing to is support by your SAN?
comp,

THe reason is that the VM was provisioned wrongly :-) a simple mouse click on the "physical" mode prevents the Snapshot of C: drive and also DRS and VMotion.
