volcopy, labelit - copy an HFS file system with label checking
/usr/sbin/volcopy [options] fsname special1 volname1 special2
/usr/sbin/labelit [options] special [fsname volume [-n]]
The volcopy command makes a literal copy of an HFS file system using a
block size matched to the device.
volcopy recognizes the following options:
-F hfs Specifies the HFS file system type.
-a Invoke a verification sequence requiring a
positive operator response instead of the standard
delay before the copy is made.
-s (default) Invoke the DEL-if-wrong verification
-y Assume a yes response to all questions
-V Echo the completed command line, but perform no
other actions. The command line is generated by
incorporating the user-specified options and
arguments with other information derived from
/etc/fstab. This option allows the user to verify
the command line.
Other options are used with 9-track magnetic tapes:
-bpi density Bits per inch.
-feet size Size of reel in feet.
-reel num Beginning reel number for a restarted copy.
-buf Use double buffered I/O.
The volcopy command requests length and density information if they
are not given on the command line and they are not recorded on an
input tape label. If the file system is too large to fit on one reel,
the volcopy command prompts for additional reels. Labels of all reels
are checked. Tapes can be mounted alternately on two or more drives.
If the volcopy command is interrupted, it asks if the user wants to
quit or wants to escape to the command interpreter. In the latter

case, other operations (such as executing the labelit command) can be
performed before returning to the volcopy command by exiting the
fsname The file system name on the device (e.g., root) being
special The physical disk section or tape (e.g., /dev/rdsk/1s3 or
volname The physical volume name; it should match the external
sticker. Such label names are limited to six or fewer
characters. The argument volname can be - to use the
existing volume name.
special1 The device from which the copy of the file system is being
volname1 The volume from which the copy of the file system is being
special2 The target device.
volname2 The target volume.
The labelit command can be used to provide initial labels for
unmounted disk or tape file systems. With the optional arguments
omitted, the labelit command prints current label values. The -n
option provides for initial labeling of new tapes only (this destroys
previous contents). The -F and -V options can be specified for the
labelit command. The behavior of the -F and -V options is similar to
their behavior in the volcopy command.
