volcopy(1M)                                           volcopy(1M)



NAME
     volcopy, labelit - copy file systems with label checking

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

     labelit special [fsname volume [-n]]

ARGUMENTS
     -a   Invokes a verification sequence requiring a positive
          operator response instead of the standard 10-second
          delay before the copy is made.

     -bpidensity
          Specifies bits-per-inch (that is, 800/1600/6250).

     -buf Uses double buffered I/O.

     -feetsize
          Specifies the size of reel in feet (that is,
          1200/2400).

     fsname
          Specifies the mounted name of the file system, such as
          root , or u1, of the file system to be copied.

     -n   Provides for initial labeling of new tapes only (this
          destroys previous contents).

     -reelnum
          Specifies the beginning reel number for a restarted
          copy.

     -s   Invokes the DEL if wrong verification sequence
          (default).

     special
          Specifies the physical disk section or tape, such as
          /dev/rdsk/c0d0s0, and /dev/rmt/0m.

     special1
          Specifies the physical disk section or tape of the file
          system being extracted that is associated with
          volname1.

     special2
          Specifies the physical disk section or tape of the file
          system being extracted that is associated with
          volname2.

     volname1

volcopy(1M)                                           volcopy(1M)



          Specifies the physical volume name of the file system
          being extracted that is associated with special1.

     volname2
          Specifies the physical volume name of the file system
          being extracted that is associated with special2.

     volume
          Specifies the physical volume name, such as pk3 and
          t0122.  The volume name should match the external label
          sticker.  Such label names are limited to six or fewer
          characters.  This argument may be replaced with a - to
          use the existing volume name.

DESCRIPTION
     volcopy makes a literal copy of the file system using a
     block size matched to the device.

     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 (for example,
     labelit) and return to volcopy by exiting the new shell.

     The arguments 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.

EXAMPLES
     The command:

        volcopy newsys /dev/rdsk/c0d0s0 1 /dev/rdsk/c1d0s0 1

     copies volume 1 of the file system labeled newsys which is
     mounted on /dev/rdsk/c0d0s0 onto volume 1 of
     /dev/rdsk/c1d0s0.

        labelit /dev/rdsk/c1d0s0 oldsys save

     relabels the file system mounted on /dev/rdsk/c1d0s0 with a
     new fsname of oldsys and a new volname of save.

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

     labelit will not work on a cartridge tape system, since such
     a tape cannot be used as a file system.  As a result,
     volcopy cannot be used with cartridge tapes, since it
     requires the tape to be labeled by labelit.
