Will Connecting To a New LUN Disconnect Other LUNs?

Hello, 

  What you are doing is VERY dangerous!  When you have such an open access control, ANY initiator on that network can connect to it and overwrite the data.  It will show as a foreign disk to be reformatted. 

 To answer your direct question, NO.  Connecting other servers to these volumes, will NOT disconnect the old ones. 

 So the first thing you need to do is shutdown the old cluster.  Then change the access on the volumes so that ONLY the new servers can access the volumes. 

 Then bring up the new cluster.  You will likely have to import it into the cluster as a resource, since it's a new cluster. 

 If you have any other volumes with open access right, then please fix them too.  Any employee with a laptop and access to that network could destroy all your data. 

 For example when you bring up this new cluster if all of your volumes on that SAN are wide open, it will see them all. So you could by accident destroy data. 

Regards,

I'm well aware of how bad it is to have access perms set to all *'s. Unfortunately, I don't think the last IT guy/company knew much at all, so it was just setup to allow everyone to connect. The whole network is messy. One thing at a time... Thanks for the input!
