Yes, but it's messy and requires you to copy the file to disk first. Oh.

In theory you could position the tape by skipping forward 2 tape files (or is it 3?) and then using the drive as the parameter for the -m flag, but in practice I would expect this to fail. Give it a try though. You still need space to process it though (see below)

Is there a physical limitation on adding a disk? They are relatively cheap now.

Can you share the output from lsvg, lsvg -l rootvg? We might be able to work something. Also, the contents of /etc/exclude.rootvg and /image.data

The mkdvd eventually calls readcd with the-w flag (for write) which is rather bizarre, but it need enough space to have two copies of the image whilst it does it. The first is to extract the image in to, then the next is to rebuild making a bootable image to write as a single IO to the media.

Do you have another AIX server with a DVD-RAM drive that does have space?


I sadly no longer have access to AIX servers, but I will see what I can remember.



Kind regards,
Robin

tcopy

tcopy(1)							   User Commands							  tcopy(1)

NAME

       tcopy - copy a magnetic tape

SYNOPSIS

       tcopy source [destination]

DESCRIPTION

       The  tcopy  utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
       contents of a tape is that there are two tape marks at the end.

       When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files.  If a des-
       tination  is  specified,  tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
       duces the same output as it does when only scanning a tape.

       The tcopy utility requires the use of Berkeley-compatible device names. For example,

       example% tcopy /dev/rmt/1b /dev/rmt/2b
