volcopy makes a literal copy of the sfs filesystem using a blocksize matched to the device.
Other options are used with both 9-track and cartridge tapes (cartridge tapes are treated as if they were 9-track tapes.)
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 filesystem 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 filesystem 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 filesystem 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.
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 ignores levels of the restored files, and access is limited only by DAC.
