How to mirror a failing drive?

only one submirror. One of the stripes on that mirror is now marked as
"Last Erred" in disksuite. It is still online but I occasionally get errors
like the following in /var/adm/messages:
May 22 11:18:20 server Error for Command: read Error
Level: Fatal
May 22 11:18:20 server unix: Requested Block: 1757020

data field), ASCQ: 0x0, FRU: 0x0
May 22 11:18:20 server unix: WARNING: md: d52: read error on
/dev/dsk/c0t12d0s6
When I try to attach another concat/stripe as a new submirror, it starts to
resync, but eventually gives up and leaves the new submirror in "Attaching"
status -- it never makes it to "OK". Is there any way to get Disksuite to
mirror what it *can* read, so that when I replace this disk, I do not lose
*all* of the data?
Thanks,
Doug
