If the controller cannot write to a destination drive (as the message
indicates), the drive is spun down. With RAID-0, this means at least one
block of data did not get written to disk. If the system crashed at this
point, probably many blocks did not get written to disk. If there was an
easy way to trick the volume back into existence, you would have no
confidence that whatever data remained, was intact, nor where any missing
blocks might be.

Your best bet is to delete the LUN, recreate it, reformat, reload from
tape...
Backups are always a requirement, but doubly so on RAID-0.

And I'd think real hard about re-using the drive that failed. I wouldn't
ever use it in another RAID-0 LUN, but I'm not sure I'd be too happy with it
in any other configuration, either.
