But only when used, isn't it? As long as you have not touched them, there's no PGMBKs except for the first one. Once he actually starts using them I would think that 550 GB of paging space might approach some other limitations in CP (though with 3390-9 not the number of cpowned volumes). -Rob -- Rob van der Heij Velocity Software, Inc http://velocitysoftware.com/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
