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 303005968 by rbatte1 on Wednesday 25th of October 2017 10:19:13 AM

Okay, a few options.
  • Have a think about using /etc/exclude.rootvg to exclude things in the rootvg not critical to the OS. The way mksysb works, it builds a list of files and funnels them into backbyname (I hope that's right) but using the -e flag on mksysb allows you to pattern-match exclude files which match, so if you have /data, you can write a line in /etc/exclude.rootvg for ./data and it's content will not be written into the image. Hopefully this will fit on disk much easier.
    .
  • Can you NFS mount some space on another server that also has a DVD-RAM device? If so, you could use that to write a DVD based on a mksysb image written across the NFS.


Could you answer the questions above so we know what we're starting with? We've all inherited odd systems so hopefully there is nothing too shocking, even if it's only one volume group.


Thanks, in advance,
Robin

bootcd2disk

BOOTCD2DISK(1)							   bootcd utils 						    BOOTCD2DISK(1)

NAME

       bootcd2disk - copy a system running from bootcd to a disk

SYNOPSIS

       bootcd2disk [-i] [-s] [-c <config directory>] [-url <url>]

DESCRIPTION

       With  bootcd2disk  a  CD  build	with  bootcdwrite can be copied to one or more Disk Partitions from the running cd-based system. Therefore
       bootcd could be used to make rescue disks.

       It is also possible to let bootcd2disk automatically find a disk, make partitions on it, copy  the  cd  to  the	disk  and  make  the  disk
       bootable.  bootcd2disk will be available as soon as your system is running from cd.

OPTIONS

       -i  With  this  option  the complete bootcd2disk runs in interactive mode and you can run each function manually. This option is useful for
	   debugging.

       -v  The option "-v" (verbose) adds messages on running.

       -s  This option can be used to disable interactive questions and to try to ignore errors.

       -c <config directory>
	   The configuration directory which normally is "/etc/bootcd" can be changed with this.

       -url <url>
	   If bootcd2disk is slow on your system (because of a slow CD/DVD drive or the HP ILO virtual CD interface), you can use an image  server
	   to  get the image from.  bootcd2disk use the SWAP partition of your upcoming system as temporary space and copy the image from the con-
	   figured image server to this partition and use it as image.	The image server url is configured with this option.

	   example install from imagesserver:
	       bootcd2disk -url http://192.168.1.1/cdimage.iso

	   Another way the increase the performance is the use of the mounted CD/DVD itself for the copy. The option "-url" is the same,  the  url
	   starts with "file:///"

	   example install from CD/DVD drive sdc0:
	       bootcd2disk -url file:///dev/sdc0

	   The swap partition of the upcoming system must have enough space to get the whole image!

       Currently no other options can be specified on command line. All other configuration has to be done in the config files.

FILES

       /etc/bootcd/bootcd2disk.conf
