NAME

volcopy,labelit − copy file systems with label checking

SYNOPSIS

/etc/volcopy [options] fsname special1 volname1 special2 volname2

/etc/labelit special [fsname [-n]]

DESCRIPTION

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

Options

volcopy recognizes the following options and command-line arguments:

-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 sequence. 

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

volcopy requests length and density information if this 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 wants 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/1s3 or /dev/rmt/0m). 

volname is the physical volume name; it should match the external sticker.  Such label names ere limited to six or fewer characters.  The argument volname can be - to use the existing volume name. 

The arguements special1 and volname1 are the device and volume, respectively, from which the copy of the filesystem is being extracted.  The arguments special2 and volname2 are the target device and volume, respectively. 

The command labelit can be used to provide initial labels for unmounted disk or tape file systems.  With the optional arguements omitted, labelit prints current label values.  The -n option provides for initial labeling of new tapes only (this destroys previous contents).
