volcopy_vxfs(1M)

volcopy_vxfs - make a literal copy of a VERITAS File System

Synopsis

volcopy [-F vxfs] [generic_options] [current_options] fsname srcdevice volname1
destdevice volname2

Description

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

Options

generic_options: Supported by the generic volcopy command (see volcopy(1M)).
current_options: Supported by volcopy_vxfs.
-F vxfs: Specify the vxfs file system type. If -F vxfs is not specified heuristics similiar to those used by fstyp(1M) are used to determine the file system type.
This command executes faster if it is not required to autodetect file system types. If possible, specify -F vxfs
-a: Invoke a verification sequence requiring a positive operator response instead of the standard 10- second delay before the copy is made.
-y: Assume a yes response to all questions.

Other options are used with both 9-track and cartridge tapes. (Cartridge tapes are treated as if they were 9-track tapes.)

-bpi density: Bits per inch.
-feet size: Size, in feet, of the reel.
-reel num: Beginning reel number for a restarted copy.
-buf: Use double buffered I/O.
-e: Process until the end of tape, then prompt for the next tape in the sequence.

If the -e option is not selected, the program requests length and density information if this information is not already provided on the command line or if this information 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 may be mounted alternately on two or more drives. If volcopy is interrupted, the user is prompted either to quit or escape to the command interpreter. If the user chooses to escape to the command interpreter, other operations can be performed (such as labelit(1M)). The user can then return to volcopy by exiting the command interpreter. NOTE: The -e and -feet options are mutually exclusive.

The fsname argument represents the mounted name of the file system being copied (for example, root or mnt).

The srcdevice or destdevice should be the disk partition or tape (for example, /dev/vx/rdsk/vol2, /dev/rmt/c0s0).

volname is the physical volume name. Such label names contain up to six characters. volname may be "-" to indicate use of the existing volume name.

srcdevice is the device from which the copy of the file system is being extracted; volname1 is the volume from which the copy of the file system is being extracted.

destdevice is the target device to which the file system will be written; volname2 is the target volume to which the file system will be written.

fsname and volname are recorded in the super-block.

Notices

volcopy does not support tape-to-tape copying. Use dd instead (see dd(1M)).
