Fiber Channel storage problems

[xPakrikx]

Hi

We have strange problem with Proxmox VE 5.3.8 + Dell SCv2020 over FC.
HDDs in storage have 512n sector size but fdisk reports physical sector size 4096 and also I/O size is very high.
On top of that we use multipathd.

Disk /dev/sdd: 3 TiB, 3298534883328 bytes, 6442450944 sectors

After i create VM on this volume and install OS i get this error:

Partition 1 does not start on physical sector boundary.
Partition 2 does not start on physical sector boundary.

VM works but there no problem like this Dell Eqallogic over iSCSI.

Thanks for advice
