CARTIS(8)                   System Manager's Manual                  CARTIS(8)



NAME
       cartis - Administration of the cartridge numbers.

SYNOPSIS
       cartis <number>
       cartis -i <ins-cart> <ins-file> [-S <cartset>]

DESCRIPTION
       The first form of this command is used to give the backup server a
       hint, which cartridge number is currently placed inside the streamer.
       If the tape has a valid afbackup label, then it is not necessary to
       tell the server, what tape is in the drive, cause it will try to read
       and evaluate it. If the tape is not labeled (e.g. if it has not been
       used before), the server has no chance to find out the number and must
       maintain it's own information about it. The server will automatically
       label new tapes, if they don't already have a valid label, the next
       time, a write operation is attempted on the tape. By issuing cartis
       after inserting an unlabeled tape you tell the server, what tape it
       should become. If you are not initially starting with cartridge number
       1 and an unlabeled tape, you have to enter this command at least one
       time.

       The second form instructs the server to write the next backup data
       stream to cartridge number <ins-cart>, starting at file number <ins-
       file>.  This is useful, if for some reason you want to take out the
       cartridge which is currently inside the drive and continue on a
       different tape or at the beginning of the tape you have put in instead.
       Note, that it usually causes problems, if you try to write at a tape
       position, that is not at the end of the last file, that has been
       written to tape. So set the <ins-file> number only to a value different
       from 1, if you really know, that this is the end of the used tape area.
       In other words, if n files are on tape, set <ins-file> to n+1. So if
       you don't know n, you're better off starting to write at the beginning
       of a new tape entering the appropriate cartis-command.  To find out,
       what the server is thinking, which cartridge is currently inside the
       drive, you can give the command afclient -q on any client. If the
       value, that is printed out, does not reflect the reality, you have to
       inform the backup server about this fact via this command entering both
       forms of this command. The first form with the real cartridge number
       and the second one with the next cartridge number and a 1 as file
       number. Then the next backup goes to the next cartridge.  You may also
       set the next backup writing position to the current file number on the
       correct cartridge. To find out, where the server side intents to write
       the next backup, enter the command afclient -Q on any client.

       It makes sense to check the consistency from time to time, if the
       backup server has the right idea of the current cartridge.

       -S <cartset>
              The cartridge set to use, where <cartset> is the number of a
              valid cartridge set on the server side. Default is 1

FILES
       /var/spool/afbackup
              Some internal state information of the server.

       /var/spool/afbackup
              The directory for logging the server actions.
