Hello,
I have 3 proxmox nodes. I want to cluster with Hitachi FC. But I couldn't get FC to work. Where am I doing wrong? Thanks for helping.

The disk seems to be present, at least on the node where you provided "multipath" output from. So that would mean you have FC working.

The first thing to do is to ensure that all 3 nodes can see the disk/s in "lsscsi" and "lsblk".
Then you need to configure "multipath" properly on all 3.
You then need to provision LVM volume group from one node only. You appear to have a partition on the disk now. Unless you have a logical reason to have it - get rid of it.
All partition and LVM manipulations need to be done on "mpath" device, not on "sdX" devices.
After you finish all of the above, you can then add LVM type storage in PVE GUI.

Good luck

I did as you said. Unfortunately, it does not appear when I want to add a disk.

I think something's going on, man. I don't understand where this datadisk came from, but it looks like it's corrupted.

I'd disable the multipath and zero out/wipe one of the underlying devices directly then. Or start from scratch on your storage array by re-creating the LUN.

I guess you can also try to wipe sdb or sdc directly at this point, you have nothing to loose.

Hello friend, I created a 2TB space with the fidsk command. Then I mapped the area I created. I'm so close. I can use this area on Host 1, but it is not active on other hosts.
fdisk /dev/mapper/mpath0_E590
vgcreate iscsi /dev/mapper/mpath0_E590-part1

I am not exactly sure what your screenshots are showing. In general, screenshots are not the best way to communicate information.
You should utilize CLI commands/outputs and encode it with CODE tags.

What I can see is that you have "?" on other nodes that possibly indicates that storage was not made properly available across the cluster.
You need to examine the output of:
lsblk - on each host
multipath -ll - on each host
cat /etc/pve/storage.cfg (should be identical on each host if cluster was properly configured)
pvesm status - on each host

The Volume Group will not necessarily be activate everywhere until your actually start using it, ie create a slice for VM running on that node or migrate a VM there.

Hello
After restarting the server everything went back to normal. Multipath works very well, thank you very much my friend, I'm glad to have you.

Don't partition unnecessarily. This is a windows thing, no one else does this. It's useless and just complicates things. Create the volume group directly on the device.
