RCLOPT goes through each platter and reads the volume table of contents
on each side. It doesn't read the files.
If you can, light it off as you leave on a Friday evening so it can run
all weekend. Depending on the number of slots in your jukebox, it could
take all weekend or it could just run a couple hours.
I don't think you'll be able to do anything else with the jukebox until
it's done. The database of platter locations is cleared at the beginning
of RCLOPT. It won't be able to find the platter you want until the
database is rebuilt. I can't swear to that though. Maybe somebody else
can help.
There's some difference with network(OS/2)-attached jukeboxes versus
direct attached. I don't have any experience with network-attached.

Subject: RCLOPT Command
Hi,
Does anyone know.when you run the RCLOPT (Reclaim Optical) command to
rebuild the optical indexes.does it read each file on each platter.or
does it read some header block that identifies the contents of that
platter?
I'm trying to figure out a few things:
- How long this might take to run the command
- If it will completely tie up all the arms while it runs such
that
no one else will be able to access it
- If the RCLOPT command gets an exclusive lock on the device so
that nothing else can read or write to/from it.
Thanks for any info you might have!
