Ok.. I have 3 ESXi 4.1 hosts. Each host connects a NAS storage system. As I had some spare network board I loaded the NAS server (Open-E) with them to give more badwidth
Each host has it's own 1GB link to the NAS, and it's own IP
Host 1 172.16.1.1 ---> Open-E 172.16.1.10
Host 2 172.16.1.2 ---> Open-E 172.16.1.11
Host 3 172.16.1.3 ---> Open-E 172.16.1.12
In each host I modified the HOST files so that CompDSS is mapped to the Open-E IP
When creating datastores I used this CompDSS:/VM1 where VM1 is the disk
So essentially each VM Host connects to the same physical location
Now.. I have just set up VCenter Server. I have added the 3 hosts and I can see the 3 Datastores (one on each Host), however
it looks like VCenter does not recognise it as the same location so I cannot VMotion from one host to another.. I have to Migrate changin the datastore.
If I was to do that then I would be writing over my existing data (Very Bad)
Can anyone suggest how I can do this.
Many Many thanks
Check storage documentations to see how to configure it for multipath and for vSphere.
But seems that the problem could be in the network configuration where each host use a different target IP.
