Connecting openfiler iSCSI to 3 ESX Hosts with vSphere
Well this is what I have.
I have 1 vsphere 4.0 server controlling all of this.
2 ESX 4.0
1 ESX 3.5
1 Openfiler iscsi with two targets each 450GB.
I have the ESX machines and the openfiler connected to a Flat network on a Gigabit switch.
Then all of the machines are connected to a gigabit switch on the main network with different NICS.
The problem I am having is I can get the iscsi setup on two ESX hosts at once, but when I try to get the 3rd machine to map the LUN it just says there is none available. I see the two disks under the storage adapter tab, but when I go to the Storage tab and look at the datastores it only shows the local disk. I do a rescan and when it completes it comes back with only the local datastore.
I have rebooted the Openfiler server and the ESX hosts in question. However when they come up a different 2 ESX servers will have the iscsi datastore mapped.
I am going batty trying to figure out why only two ESX hosts can have the iscsi attached? I want to use this for VMotion and have had it working in the past with just two ESX Hosts.
