This advice is general because I haven't seen SCO unix for many years.

Reading between the lines you appear to be trying to move an existing running SCO unix system to a virtual machine. You have already hit the 2 Gb limit on any file (including a cpio archive) which is found in old versions of unix.

Personally I wouldn't attempt to move the Operating System. I would cold install on the new platform and then transfer any data files. Assuming you have a technique to boot the result (a technique unknown to me), copying all the files is straightforward providing that the destination filesystem can be handled by the source Operating System.

Try using "find ." piped to "cpio -p". This is documented in both "man find" and "man cpio". The key point here is that we are not creating a "cpio archive" (which could exceed 2 Gb) we are just copying files (none of which could possibly exceed 2 Gb). It is what "cpio" is for.

Sample example command sequence follows: Please check exact syntax on your computer with your "man" pages and do rehearse on expendable filesystems. I recall that the parameter "-xdev" used to be "-mount" in SCO unix but things have probably changed in the meantime.

You cannot move all filesystems in one operation. It needs one copy operation per filesystem. Start with root then each mountpoint in descending order of directory hirearchy. Ensure that the target filesystems match the source filesystems.

Code:

cd /old_mountpoint
find . -xdev -depth -print | cpio -pdumv /mnt/new_mountpoint

rpm2cpio

rpm2cpio(1)							   User Commands						       rpm2cpio(1)

NAME

       rpm2cpio - convert Red Hat Package (RPM) to cpio archive

SYNOPSIS

       rpm2cpio [file.rpm]

DESCRIPTION

       The  rpm2cpio  utility converts the .rpm file specified as its sole argument to a cpio archive on standard output. (See NOTES.) If no argu-
       ment is given, an rpm stream is read from standard input. In both cases, rpm2cpio will fail and print a usage message if the standard  out-
       put is a terminal. Therefore, the output is usually redirected to a file or piped through the cpio(1) utility.

EXAMPLES

       Example 1: Converting an rpm file

       example% rpm2cpio Device3Dfx-1.1-2.src.rpm | cpio -itv
       CPIO archive found!
       -rw-r--r--   1 root  root    2635 Sep 13 16:39 1998, 3dfx.gif
       -rw-r--r--   1 root  root   11339 Sep 27 16:03 1998, Dev3Dfx.tar.gz
       -rw-r--r--   1 root  root    1387 Sep 27 16:04 1998, Device3Dfx-1.1-2.spec
       31 blocks

       Example 2: Converting from standard input

       example% rpm2cpio < Device3Dfx-1.1-2.src.rpm | cpio -itv
       CPIO archive found!
       -rw-r--r--   1 root  root    2635 Sep 13 16:39 1998, 3dfx.gif
       -rw-r--r--   1 root  root   11339 Sep 27 16:03 1998, Dev3Dfx.tar.gz
       -rw-r--r--   1 root  root    1387 Sep 27 16:04 1998, Device3Dfx-1.1-2.spec
