How to do bad block replacement on RA81 under 4.3-tahoe?

[Marc Lesure]

I thought the 4.3-tahoe device driver for the ra disk series did bad block
replacement until I started getting these error messages over and over.

uda0: hard error datagram: unit 2: level 0 retry 133, lbn 555523: data error (uncorrectable ecc) (code 8, subcode 7)
ra2: bad block report: 555523
ra2g: hard error reading fsbn 179952-179967 data error (uncorrectable ecc) (code 8, subcode 7)

The man page for the uda says to get DEC to replace the bad block via EVRLK.
Since we are not on DEC maint., is there another way of doing this?  With
the RM05 disks I used 'badsect', but this doesn't seem to work with the
RA81.
