when changing the motherboard, the disks do not appear

Hi team,

I have changed the motherboard in my sparc t5-2 server, but when I start the server, I see that services such as local filesystem are in a maintenance state, and I have checked with the format command, and I see that disks are missing and therefore, the local file system It is under maintenance and I do not have access to the areas that use those disks.

note: when re-entering the previous motherboard, all services and disks are ok
