mksyb to a file and then to a cd help

[nomad1945]

Hello:

I have a aix5.3 system i need to make a mksyb. The DVD is not writable.

How do it, or can I do a mksysb to a file, ftp it to another system where may have a writable cd to it, then transfer that to the cd and have it bootable?
is that possible?

thanks
scott

From the man page for mksysb:

"Creates an installable image of the root volume group either in a file or onto a bootable tape."

So yes, I assume you should be able to do as you describe.

I do this at regular intervals. I also have the added disadvantage of not having a CD writer on any of my AIX systems. The basic steps are

1. mksysb <filename>
2. mkcd to produce an iso image
3. ftp the image to my CD writer
4. burn the CD using Nero

man mkcd will give you all the flags. BTW one thing that stopped me was that the path names need to be absolute (I found i was writing massive files into the '/' directory).

Note that mkcd is clever enough to make sets of CDs if the image is >800Mb.

The reason I do this is to be able to return my playbox to a preset (virgin) state. The cd lives in the drive. I've edited /bosinst.data to make it non interactive (look on the IBM site for details of this). A rebuild is simply a matter of

bootlist -m normal cd0
shutdown -Fr
