I have this problem where a new install of Windows Server 2022 Datacenter on DELL R650 doesn't show any of the DELL Unity LUNs as available disks on Disk MGMT to format.

 

iSCSI Initiator settings show the LUNs correctly recognized.

MPIO settings have iSCSI Multipath checked

 

When I uninstall the MPIO service I can see the LUNs as available disks on Disk MGMT, but they show repeated the number of path the server has available

 

Event viewer shows an error that tells "an error occurred while the system tried to claim a Multipath I/O path"

 

Any ideas?
