The answer was provided by alan_at_nabeth.cxo.dec.com, and I
will summarize. The underlying disks in my case are SCSI,
so the steps were :
o Identify the subdisk in the LSM volume containing the
bad sectors. This was done using 'volstat -f f -s' to
show read/write errors on the LSM subdisks.
o Use 'scu -f /dev/rrz20c verify media' to find the bad
sectors on the disk.
o Use 'scu -f /dev/rrz20c reassign lba ######' to reassign
the sectors. For some reason, this command failed when
trying to use it from the 'scu>' prompt, but it worked
when entered in full on the shell command line.
