Do we need to create a different iSCSI group for different host? Because I thought iSCSI group is to group hosts/initiator based on OS like vmware, Windows.
My case is:
I have an ESXi host: vm1.
iSCSI group: ig_vm1
Using lun setup I map the lun and the iSCSI group
Now I have a 2nd ESXi host: vm2
Using lun setup I map the lun to the SAME iSCSI group (ig_vm1).
I cannot see the LUN from vm2
The LUN apprears in vm1
I unmap the LUN /vol/vol0/qtvm2/lun0 from ig_vm1 and create another iSCSI group for it and map it. Now it shows in vm2.
We should create different iSCSI group for each host?

It depends -- if you have your ESX servers managed via VirtualCenter and want to vMotion between the ESX servers, you need all ESX servers to have access to the same filesystems. In that case, you'd simply make a single igroup and put all the ESX iSCSI IQN's into it.
If the hosts aren't managed by VirtualCenter, each ESX server should only have access to its own filesystem.
