VMware Sharing Same SAB Storage Among VMs.

I have an ESXi connected via iSCSI directly to a SAN.  I have one VM on the ESXi.  That VM is connected to an iSCSI SAN.  

What's the best way to go about making another VM just like the first one that uses the same data on the SAN?

In answer to your first question No.

Multiple VMs cannot access the same iSCSI volume or LUN, concurrently, if you do this the LUN or volume will become corrupted.

if you want VMs accessing the same data you need to use Windows Shares or NFS.

Clone the VM using vCenter if available.

or use this method in my article

When I do this I get an error that says insufficient disk space.  I'm not sure how to check what is insufficient.

So now I'm very confused.  I have a VM that is using the SAN storage but the whole iSCSI initiator thing I did yesterday isn't even turned on.

check the datastore storage space

The summary for the VM shows 2 datastores.  datastore1 and Production. 527 GB Provisioned, 527 GB Used.

I want the VMs to share the same data.

you have two VMs, and want to share the same data?

That is the reason for lack of storage space......

datastore is full.

I have one VM right now.  I want to make several that can access the same volume data  on the SAN.

I think datastore1 is on the physical hard drive on the machine.  I don't even want to use that.

I would like everything to reside on the SAN.

so copy the VM to Production.

or Create a New VM and select the SAN datstore, is the SAN datastore Production?

Yes, SAN datastore is production

do you want to store the VM on the SAN, or have the OS in the VM access the SAN via iSCSI?

how does this existing VM access the SAN?

okay so VMs stored on the SAN?

I want to have the OS on the VM access SAN via iSCSI.  Can I make all my VMs access the same volume on the SAN?

Yesterday I made a VM that accessed the SAN via iSCSI.  I tried coping that VM and it broke the first VM.  Now the copied VM accesses the proper volume but the Windows iSCSI initiator isn'teven running.

I'm starting over.  I'm making a VM that uses the majority of Production datastore as a file server and all my other VMs will access that server for data.  Am I on the right road now?

Correct, thats the way to do it. with Windows File Shares
