volcopy(1M)                                           volcopy(1M)



     NAME
          volcopy, labelit - copy file systems with label checking

     SYNOPSIS
          /etc/volcopy [-a] [-bpidensity] [-buf] [-feetsize]
          [-reelnum] [-s] fsname special1 volname1 special2 volname2

          /etc/labelit special [fsname volume [-n]]

     DESCRIPTION
          volcopy makes a literal copy of the file system using a
          blocksize matched to the device.  Flag options are:
             -a   invoke a verification sequence requiring a positive
                  operator response instead of the standard 10-second
                  delay before the copy is made,
             -s   (default) invoke the DEL if wrong verification
                  sequence.

          Other flag options are used only with tapes:
             -bpidensity  bits-per-inch (i.e., 800/1600/6250),
             -feetsize    size of reel in feet (i.e., 1200/2400),
             -reelnum     beginning reel number for a restarted copy,
             -buf         use double buffered I/O.

          The program requests length and density information if it is
          not given on the command line or is not recorded on an input
          tape label.  If the file system is too large to fit on one
          reel, volcopy will prompt for additional reels.  Labels of
          all reels are checked.  Tapes may  be mounted alternately on
          two or more drives.  If volcopy is interrupted, it will ask
          if the user wants to quit or wants a shell.  In the latter
          case, the user can perform other operations (e.g., labelit)
          and return to volcopy by exiting the new shell.

          The fsname argument represents the mounted name (e.g., root,
          u1, etc.) of the filsystem being copied.

          The special should be the physical disk section or tape
          (e.g., /dev/rdsk/1s5, /dev/rmt/0m, etc.).

          The volname is the physical volume name (e.g., pk3, t0122,
          etc.) and should match the external label sticker.  Such
          label names are limited to six or fewer characters.  volname
          may be - to use the existing volume name.

          special1 and volname1 are the device and volume from which
          the copy of the file system is being extracted.  special2
          and volname2 are the target device and volume.

          fsname and volname are recorded in the last 12 characters of
          the superblock (char fsname[6], volname[6];).

          labelit can be used to provide initial labels for unmounted
          disk or tape file systems.  With the optional arguments
          omitted, labelit prints current label values.  The -n option
          provides for initial labeling of new tapes only (this
          destroys previous contents).

     EXAMPLE
               volcopy newsys /dev/rrp15 1 /dev/rfd0 1

          copies volume 1 of the file system labeled newsys mounted on
          /dev/rrp15 onto volume 1 of /dev/rfd0.

               labelit /dev/rfd0 oldsys save

          relabels the file system mounted on /dev/rfd0 with a new
          fsname of oldsys and a new volname of save.

     FILES
          /etc/volcopy
          /etc/labelit

          /etc/log/filesave.log   a record of file systems/volumes
                                  copied

     SEE ALSO
          sh(1), fs(4).

     BUGS
          Only device names beginning /dev/rmt are treated as tapes.
