Note in your metadb - looks like someone added to the metadb but never rebooted - that's usually why you get the unknown in the status although it's possible you are also getting it because the disks are bad. The good thing is that there are so many copies of the metadb - so you can replace the bad disks without no worry about losing anything.

As far as the bad disk, get the replacement disk drives and you can use the metareplace command. Or you can use metadetach and metaclear to remove them from the metastat and replace the drives, format, and readd them. You can hot swap the drives so you should not need any down time.

Also, insure that the boot device is c1t0d0s0 and not c1t1d0s0. You don't want to hot swap or remove the drive you are booted off of (inital boot will be off one drive and then the mirrors come into play). Just check the output of eeprom and look for boot-device - hopefully it isn't simply "disk:a" but gives you the output that you would be able to tell which drive it really is. If not, then you can play it safe and reboot into single user to do the drive replacements. More info can be found in this thread
The boot disk looks like it refers to the c1t0d0 disk according to eeprom. It doesn't indicate the slice.

I think that error occured because of an incorrect powerdown... But I'm not sure because I just got a hold of this box. As I said the drive light indicators on the outside of the box aren't indicating any faults. On the negative side, format does not list c1t3d0, but it does list c1t1d0 as well as all other drives.

Is there any way to tell if the disk is definetely bad? The box was recently moved, so I am concerned the drives may have been rattled around a bit, maybe even come unseated. I was thinking of powering down, reseating all the drives, then booting and running touch /reconfigure. If the drive was previously detected in the system would I even need to do that for it to come back online?

Thanks!

unknown

UNKNOWN(1)						      General Commands Manual							UNKNOWN(1)

NAME

       unknown - identify possible genotypes for unknowns

SYNOPSIS

       A program to rapidly identify which genotypes are possible for individuals typed as unknowns in the input pedigree.

       unknown [ -cl ]

DESCRIPTION

       unknown infers possible genotypes and mating combinations for parents with unknown genotypes for ilink(1), mlink(1) and linkmap(1).

OPTIONS

       -c     Use conditional allele frequencies.

       -l     Choose a good set of loop breakers automatically.

RETURN VALUE

       0     Successful completion

ERRORS

       10    File not found
       255   Failure

EXAMPLES

       Normally, unknown(1) is run immediately prior to its sister programs, ilink(1), mlink(1) and linkmap(1), like this:

       unknown
       mlink

FILES

       unknown(1) reads the two files pedfile.dat and datafile.dat as its own input and produces various temporary files that are used as input to
       the next program. These temporary files are ipedfile.dat, upedfile.dat, speedfile.dat and newspeedfile.dat.

NOTES

       unknown(1) is part of the FASTLINK package, which is a re-implementation of the LINKAGE suite  of  computer  tools  that  help  investigate
       genetic linkage as first proposed G.M. Lathrop, J.M. Lalouel, C. Julier, and J. Ott.
