Re: [foxboro] Broken Concatenated Disk

I think the answer in the response from the "metastat" command you have 
supplied:

>     Invoke: after replacing "Maintenance" components:
>                 metareplace d5 c0t2d0s7 <new device>

Did you try that?

HH 835 may be of some help too. Some translation I did from this HH to the 
newer id's used today:
When a device (this example could be for your drive but the example was for a 
mirrored drive that "nds_maint"):

metadetach -f d5 d15<cr>
metattach d5 d15<cr>

I'm almost sure you will need to roll back a tape by the way. I don't think 
that the data can be trusted when only one of the two disks is replaced.
