< Well, after another try to sort this I come to the conclusion that Solaris is 
very picky about the discs. The CDRW's I use are Nashua and Verbatim. DVD-RW 
from Philips are accepted though. The strangest thing is, when I insert a CDRW 
in my DVD-ROM drive Solaris' Volumemanager thinks it must be formatted. This 
behavior is wrong in my opinion. To make things clear I include a log a typical 
session.

 Yes, this can be annoying.  I get this every time I want to burn a cd/dvd.
 Thankfully a solution is already being worked upon: Tamarack.

  Better than the old volume-manager in oh sooo many ways.

  Try use s2 instead of p0.  You've already found a hsfs on slice 2 not 
  partition 2. (yes, solaris's use of sX/pY for media can be confusing).

  Odd and annoying, but being addressed.

  You using cdrecord :)  Which was first built/developed on Solaris by Joerg
  oh so long ago...
