The p* devices are probably not what you're looking for.  The p0
device is generally "the whole disk", including access to the
partition table, etc.  The p1-4 devices are for access to the classic
MBR primary partitions, of which there can only be four.

If you've created a modern, EFI/GPT style partition table, and
format(8) can see those GPT partitions, then what you want are the s*
or "slice" devices, which is how we refer to them.  You should ideally
have one slice device for each GPT partition.



Cheers.
