NAME
volcopy_vxfs: volcopy, labelit - copy a VxFS file system with label checking
SYNOPSIS
/usr/sbin/volcopy
[-F vxfs][-V
][-a][-s][-y] fsname special1 volname1 special2 vol-
name2
/usr/sbin/labelit
[-F vxfs][-V
][-n] special [fsname volume]
DESCRIPTION
volcopy makes a literal copy of a VxFS file system using a block size matched to the device.
Options
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 requir-
ing 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
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.
