Need UDA/RA81 Problem

[Greg Cline]

We're having some difficulties with the UDA50 controller on a machine 
here with 4 RA81's.  We originally  suspected a partiton problem, but 
recent net.unix-wizards postings suggest an RA81/RA81 problem.  Can
anyone elaborate?

We get both hard AND soft errors:

uda0: soft error, disk transfer error, unit 1, grp 0xffff8201, hdr 0xc473f, event 0650
uda0: soft error, disk transfer error, unit 1, grp 0x0, hdr 0xc4742, event 0710
uda0: soft error, disk transfer error, unit 1, grp 0xffff8401, hdr 0xc4743, event 0350
uda0: hard error
uda0: hard error, disk transfer error, unit 1, grp 0xffff8500, hdr 0xc4744, event 0350
ra1f: hard error sn194920 uda0: soft error, disk transfer error, unit 1, grp 0x0, hdr 0x9dc15, event 0750

All partitions except the root 
partition and the swapping area are even multiples of whole cylinders
AND occupy the entire disk area as defined in /etc/disktab.
