If -at IPL time- a volume is included in the CP OWNED list, it is attached to SYSTEM automatically.
At runtime: when you ATTACH a disk to SYSTEM, CP will verify if it is in the CP OWNED list. In any case, at ATTACH TO SYSTEM time: for disks in the CP OWNED list, and only for those, CP will read the ALLOC map to see what it can use (PAGE, SPOOL, etc). 2010/11/19 George Henke/NYLIC <[email protected]> > Also it must be ATTACHED to SYSTEM. > > I had a problem recognizing my second page pack at level 2 because it was > not attached to level 2 as SYSTEM. > > q dev# and/or q dasd volser should show its attach status, > > > > > *[email protected]* > Sent by: The IBM z/VM Operating System <[email protected]> > > 11/19/2010 06:40 AM > Please respond to > The IBM z/VM Operating System <[email protected]> > > To > [email protected] > cc > Subject > Re: Page volume not recognized after IPL > > > > > Hello, Ashwin: > For the dasd to be recognized it must be formated AND allocated as PAGE > with CPFMTXA, AND must be defined as Owned into SYSTEM CONFIG. > Is the DVRESB a new Page dasd? > To check dynamically, use these commands: > > CP DEFine CPOWN SLOT 6 DVRESB > followed by other CP QUERY ALLOC > > If the Query shows the page area, the problem is in the SYSTEM CONFIG.
