Hi
I am setting up a new environment with 2 x DELL R410 hosts and a DELL MD3200i iSCSI SAN. Running ProxMox 2.1-1
The hosts have 4 NICS, two for networking and two for iSCSI.
There are 2 x 4 iSCSI NICs on the MD3200i.
I have an HP switch with VLANs between the hosts and iSCSI.
There is one LUN on the SAN which I want to share between the two hosts to allow migration of VMs between the hosts.
I spent 6 hours researching the setup of the disk array and multipath but I'm actually more confused now than before I started.
I think I have multipath working as I get the following on both hosts (I am only using one NIC on each controller of the MD3200i):
The problem I am faced with now is how to get the storage usable by the hosts. I am unsure what to do next- with command line and what can be done in the v2.0 GUI.
What is the relationship between Multipath, volume groups and LVM volumes?
Do I need to create a volume group?
Do I have to do it manually or is it done automatically when I add the storage through the gui?
There doesn't seem to be a definitive guide on how to achieve what I want from start to end.
Any help would be appreciated.
thanks
Gordon
