NAME [Toc] [Back]
volcopy_vxfs: volcopy, labelit - copy a VxFS file system with label
checking
SYNOPSIS [Toc] [Back]
/usr/sbin/volcopy [-F vxfs] [-V] [-a] [-s] [-y] fsname special1
volname1 special2 volname2
/usr/sbin/labelit [-F vxfs] [-V] [-n] special [fsname volume]
DESCRIPTION [Toc] [Back]
volcopy makes a literal copy of a VxFS file system using a block size
matched to the device.
Options [Toc] [Back]
volcopy recognizes the following options and command-line arguments:
-F vxfs Specify the file-system type (vxfs).
-V Validate the command line options, but do not
execute the command. If the options specified are
valid, -V echoes the complete command line. If
the options specified are not valid, -V prints an
error message.
-a Normally, before copying the file system, volcopy
delays so that the user can interrupt the copying
if needed. This option invokes a verification
sequence requiring a positive operator response
instead of the standard delay.
-s (default) Before copying the file system, prints a
message and allows the user to interrupt the copy
if needed.
-y Assume a yes response to all questions
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 it is not
given on the command line or if it is not recorded on an input tape
label. If the file system is too large to fit on one reel, volcopy
prompts for additional reels. Labels of all reels are checked. Tapes

can be mounted alternately on two or more drives. If volcopy is
interrupted, it asks if the user wants to quit or to escape to the
command interpreter. In the later case, other operations (such as
labelit) can be performed before returning to volcopy by exiting the
command interpreter.
The fsname argument represents the file system name on the device
(e.g., root) being copied.
special should be the physical disk section or tape (e.g.,
/dev/rdsk/c0t4d0s0 or /dev/rmt/0mb).
volname is 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.
The arguments special1 and volname1 are the device and volume,
respectively, from which the copy of the file system is being
extracted. The arguments special2 and volname2 are the target device
and volume, respectively.
The labelit command can be used to provide initial labels for
unmounted disk or tape file systems. With the optional arguments
omitted, labelit prints current label values. -F and -V options can
be specified for labelit. The behavior of -F and -V options are
similar to the behavior of volcopy. The option -n of labelit provides
for initial labeling of new tapes (this destroys previous contents).
WARNINGS [Toc] [Back]
volcopy and labelit will be unsupported in a future release. Use
vxdump(1M) and vxrestore(1M) for backup and restore, or use an
application-specific utility. Use dd(1) to make a literal copy of the
filesystem.
