NAME
volcopy (sfs) - make a literal copy of a sfs file system
SYNOPSIS
volcopy [-F sfs] [generic_options] [current_options]
fsname srcdevice volname1 destdevice volname2
DESCRIPTION
generic_options are options supported by the generic volcopy
command. current_options are options supported by the s5-
specific module of volcopy.
volcopy makes a literal copy of the sfs file system using a
blocksize matched to the device.
The options are:
-F sfs Specify the sfs-FSType.
-a Invoke a verification sequence requiring a
positive operator response instead of the
standard 10-second delay before the copy is
made. A positive response is always required to
override warnings about mismatched system names.
Other options are used with both 9-track and cartridge tapes
(cartridge tapes are treated as if they were 9-track tapes.)
-bpidensity bits per inch
-feetsize size of reel in feet
-reelnum beginning reel number for a restarted copy
-buf use double buffered I/O
-e process until the end of tape, then ask for the
next tape in sequence.
If the -e option is not selected, the program 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
may 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 latter case, the
user can perform other operations (such as labelit) and return
to volcopy by exiting the command interpreter. Note that the
-e and -feet options are mutually exclusive.
The fsname argument represents the mounted name (for example,
root, usr, and so on) of the file system being copied.
The srcdevice or destdevice should be the disk partition or
tape (for example, /dev/rdsk/1s5, /dev/rmt/c0s0, and so on).
The volname is the physical volume name. Such label names
contain up to six characters. volname may be ``-'' to use the
existing volume name.
srcdevice and volname1 are the device and volume from which
the copy of the file system is being extracted. destdevice
and volname2 are the target device and volume.
fsname and volname are recorded in the superblock.
When copying from disk to tape, volcopy saves the system name
and the size and creation date of the LTDB. When copying from
tape to disk, volcopy issues warnings if the system name does
not match or the LTDB has changed. A positive response is
required to continue processing after a warning is issued.
NOTICES
volcopy does not support tape-to-tape copying. Use dd(1M) for
tape-to-tape copying.
DIAGNOSTICS
The following security warnings may be displayed when
restoring a file system from tape:
UX:volcopy:WARN: System name name of creating system does
not match system name name of destination system.
Unless the two systems have identical user, group, and level
databases, security attributes of the restored files will be
invalid. Only use volcopy to transfer file systems between
systems if the security databases of the two systems are
identical.

UX:volcopy:WARN:System is single level, archive is multilevel.
This indicates MAC is not installed on the current system, but
was installed on the system when the backup was done. The
system will ignore levels of the restored files, and access
will be limited only by DAC.
