Re: Adding Slots for CP volumes in the System Config file
Thanks, Kris - of course, you're right. Because I always add many Reserved slots, that practice lead me to 'mis-remember'. Thanks again.

Re: Adding Slots for CP volumes in the System Config file
check your System Config and see what your next reserved slot is: enter - DEF CPOWN SLOT nnn volid with nnn being the next reserved slot and the pack is not attached to the system after the define attach it to the system and it will be found. like Mike said be sure you add it into the System Config also and also add a LOT of reserved slots. good luck Bill Munson Sr. z/VM Systems Programmer Brown Brothers Harriman CO. 525 Washington Blvd. Jersey City, NJ 07310 201-418-7588 President MVMUA http://www2.marist.edu/~mvmua/ Mike Walter mike.wal...@hewitt.com Sent by: The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU 02/10/2009 11:36 PM Please respond to The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU To IBMVM@LISTSERV.UARK.EDU cc Subject Re: Adding Slots for CP volumes in the System Config file I believe that there are CP commands to DEFINE new CP_OWNED slots dynamically.

Re: Adding Slots for CP volumes in the System Config file
Hi Alan, So that I understand what you are saying, I would add the CP-OWNED SLOT 255 RESERVED where in the SYS CONFIG file? And when this is added does it mean that let's say my last RESERVED SLOT in the SYS CONFIG file was 10 and I added the 255 SLOT statement after this and I now wanted to add a CP-OWNED volume dynamically I would do a CP OWNED command using SLOT 11 and so on. I then assume I would go into the SYS CONFIG file and add a CP-OWNED SLOT statement (CP_OWNED SLOT 11) before the CP_OWNED SLOT 255? I hope this makes sense!

They don't even have to be listed in order of the slot numbers. Having said that, for readability, maintainability, and to keep us all sane, it is a good practice to specify them all together and in slot numnber order.

Adding Slots for CP volumes in the System Config file
Hi I have a quick question. I need to add more SLOTS in the SYSTEM CONFIG file I am assuming that it is as easy as duplicating existing reserved SLOTS. Is this a fair assumption? Also I believe the max number of SLOTS is 256 is this correct? One last thing is there any performance or other implications to be aware of when increasing the number of SLOTS? Thanks in advance for your help!! Terry
Re: Adding Slots for CP volumes in the System Config file
Yep, easy as that -- just DO NOT change the SLOT number on any volumes allocated with SPOOL space!! No significant overhead in the 255 max slots. Changes will be effective at the next IPL, but I believe that there are dynamic CP commands to get you going without an IPL.
