Full Discussion: Can I use mkdvd to create bootable DVD from mksysb on tape
Operating Systems AIX Can I use mkdvd to create bootable DVD from mksysb on tape Post 303005850 by rbatte1 on Tuesday 24th of October 2017 05:11:19 AM

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

       c1541 [options] [image]

DESCRIPTION

       c1541  is a stand alone program that can be used for D64, D71, D81, X64 and G64 disk image file maintenance.  It is part of the VICE emula-
       tor.

       c1541 can be used both in interactive and batch mode.  It will start in interactive mode if no images and no options are  specified  or	if
       one image is specified; when started in interactive mode, command line editing and command history are available.

       Each command line option for use in batch mode has an interactive mode counterpart, that is shown in parenthesis.

       -attach image (attach image)
	       attach image for use.  All consequent commands in interactive mode will refer to this image.

       -detach image (detach image)
	       detach image from c1541.

       -format image (format image 'name,id')
	      format the disk image image with the specified label.  image is created if it does not exist.

       -delete image files... (delete files...)
	      delete files from image

       -list image (list)
	      list directory of image.

       -validate image (validate)
	      validate mage.

       -copy image oldname1 [oldname2...] newname (copy oldname1 [oldname2...] newname)
	      concatenate oldname1, oldname2... into newname on image (can be used to copy files).

       -create image dump ['descr'] (create image dump ['descr']
	      build image from raw dump file dump (i.e. convert from D64 to X64 file).

       -tape image tapeimage [files...] (tape image tapeimage [files...])
	      transfer files from tapeimage to image (default is all files).

       -read image 1541name [fsname] (read 1541name [fsname])
	      extract 1541name from the disk image into fsname (1541name by default) from image.

       -extract image (extract).
	      extract all files from image.

       -write image fsname [1541name] (write fsname [1541name])
	      write fsname to image as 1541name (fsname by default).  (works with P00 files as well).

       -block [drive:] [track] [sector] [disp] (block [drive:] [track] [sector] [disp])
	      show disk blocks in hex format.

       -info image ['descr'] (info ['descr'])
	      show version information about image.

       When more than one command is specified in batch mode, all of them are executed in the same order they have on the command line.

       If you use - as a file name, it stands for stdin or stdout.
