Looking at the hp (RP-04/5/6) man page in V7, 32/v, and 3bsd the
convention was rpN, where 0 <= N <= 7 were partitions on the first
drive, and rp8 was the first partition on the second drive.  rp0 was
root, rp1 was swap, rp2 and rp3 (in the v7 man page) are unassigned.

The rpNx convention, where N is the drive number, with "c" as the
whole disk is present in the 4.1BSD hp(4) man page.
