Dear managers,
we have a production machine Sun Fire 240 with two mirrored 73 GByte
SCSI-disks. The mirror was fine for a year. Now I get the following:

c1t0d0 Yes id1,sd@SSEAGATE_ST373307LSUN72G_3HZ6Y1YR00007431G08H
The system is up and running but very obviously there is something
wrong with the second disk. I have never encountered such a situation
and am not sure what to do now. I would really appreciate your hints
before I do something wrong with a production machine.
Thanks a lot in advance!
Regards,
Andreas
