Hello.
I have a proxmox cluster and ME4024 storage.
Configured iSCSI Multipath as written in the instructions.
For the test, I disconnected the port wire, the address of which is connected in proxmox. At the same time, the machine continued to work for me until I turn it off.
The main question.
After pulling out the wire, the device and the LVM drive become with question marks.
I think that means. that iSCSI Multipath does not work and does not switch to another route.
Is that how it should be or not?
