Hello,
i have 2 server with ESXi installed and iSCSI configured with two interface each for redundant connection.
I will update one of these two server with proxmox 8, pass all vms then update the other server.

I have as a storage a ME5024, two address each pool.
How can i configure iSCSI and multipath (that's what is called, i think(?) ) on the new proxmox to make it work like the new system?

Thanks for your help

Thanks for your response.
Have you already done a similar operation?

I read the documentation and one things it doesn't sound to me: after the edits to multipath file, it says:
Via the GUI (only applicable for iSCSI LUNs): First, create an iSCSI storage in the GUI as described above.

I will se the LUNs in the Storage list, or only when i'll create LVM on iSCSI i see the new LUNs?

Also, on a second note, i read something related to open-iscsi, that's not needed in my case?
 
PS fixing post as I misread it due to lack of coffee in the blood stream :-)

Hi @Alyke , there are two primary ways to configure iSCSI in PVE: manual and via PVE. You should try to stick to PVE managed option, as it is easier. Once you've configured the iSCSI storage pool your devices will be discovered, and if there are more than 1 path, the system will see duplicate entries. That would be the time to configure the Multipath.
Once Multipath is in-place, you can then place LVM on Multipath device. It is important to use DM device, not the underlying SDx.

The article below goes over a lot of the concepts:

Hi @Alyke , presumably you already have the iSCSI scaffolding in your existing cluster. As such, you should not need to do anything as you are upgrading an existing, already configured PVE node.

You have asked about multipathing - do you not have it configured now on your nodes?

Hi,
I don't have anything at the moment, it will be a new installation.
Now there are two ESXi server, i will install Proxmox on one first, configure everything, import all vms then update the other server.
I need to replicate what is now on ESXi in a Proxmox Cluster

I think manually is as the link you posted ^

Then, after that I need to set up Multipath to have everything working
