VIOS backup to DVD

Trying to backup the VIOS system to DVD using the backupios command. The command completes and reports success yet there is nothing written to the DVD.

Hardware: Blade H series JS23/43

Code:
$ ioslevel
2.1.2.13-FP-22.1 SP-02

# lsdev -Cc cdrom
cd0 Available 2.1.2.3- USB DVD R/RW or RAM Drive

$ backupios -cd /dev/cd0 -cdformat -nosvg

The current work around is to make an image and then ftp it to another system to burn it to DVD. Yet I would rather find out what I'm missing here to get this working.

During this process it does not seem that the system is doing anything with the DVD drive.

filosophizer - tried the "smitty mkdvd" command. The results were the same "burn_cd was successful" yet nothing is written to the DVD. It was a bit more verbose yet was not giving an error.

lo-lp-kl - Thanks for the link, I was in there before I posted here. I try and do my homework before asking for help - sometimes I do miss things though.

So far I have tested using DVD -R, DVD +R and DVD -RAM with the same results. So for grins I thought I might test without any media just to see if I could get an error message:

So it does seem to realize that the drive contains media.

may be you don't have cd-writer or dvd-writer

may be it is only CD-ROM

can you check what is written on the CD-ROM ?

The tray in the blade is a slimline variety (common for IBM):
DVD Multi Recorder
RW DVD Re-Writable

My thought on this issue is how the device shows up under AIX as a USB device.

You need a special type of DVD Media for pseries to make the backup on.

I remember I was facing the same issue, until i researched online...
This media is called DVD-RAM. Try with this media and it will 100% work.
