If you don't burn DVDs, you can ignore this message

My putback of:

    PSARC/2005/606 dvd+rw-tools
    6346516 add dvd+rw-tools (PSARC/2005/606)

added another DVD burner to Solaris which seems to work
quite well with USB and 1394 burners

(cdrw is only recommended for on-board burners and cdrecord
cannot handle > 2GB images)).

For more info on dvd+rw-tools:

        http://fy.chalmers.se/~appro/linux/DVD+RW/

you can get the packages from /ws/sfwnv-gate/packages/i386/nightly-nd
or /ws/sfwnv-gate/packages/sparc/nightly-nd

SUNWdvdrw       - growisofs, dvd+rw-booktype, dvd+rw-mediainfo
                        dvd+rw-format, dvd-ram-control
SUNWdvdrwS      - source package
SUNWsfman       - man pages

There is only a man page for growisofs unfortunately.
Work has started to get the nautilus CD burner working which uses
cdrecord and growisofs as backends.

The easiest way to burn a Solaris DVD is:

# rmformat
<find your dvd burner, eg c2t0d0p0>

# growisofs -dvd-compat -Z /dev/rdsk/c2t0d0p0=solarisdvd-iso

yes, growisofs works with vold (/vol nodes).

You can verify the DVD as follows (thanks to juergen keil who posted
this recently):

( eject optical media after writing, re-insert media [so that Solaris
   notices the new content on the optical media] )

# dd if=/vol/dev/aliases/cdrom0 bs=32k | cmp - solarisdvd-iso

"cmp" should find no differences, and no errors should be logged to
the console or /var/adm/messages.

If you've burned CD-{R,RW} media, you can also try a "readcd -c2scan"
test on the media. The readcd utility is part of the cdrecord
package (also on sfw).

The 32k is important because on ferrari, we limit transfers to 32k

I burned using growisofs a b27a DVD with an Addonics DVD RW
USB2.0 burner connected to my ferrari, then rebooted from the
DVD and installed on a USB2.0 Maxtor OneTouch drive

Amazingly, it wasn't even that slow (one hour) and it rebooted
flawlessly from the OneTouch disk.

You can file bugs under solaris/utility/dvd+rw-tools.
