You could change the UCB in your IODF to come up OFFLINE during an IPL. It would be available to be varied online if needed, but this way it would default to being offline when you come up.
The second option is to rename the dataset on the volume to something else, and then you could quickly rename it back if you found that you needed to add the volume. Something like SYS1.HASPACET should work? -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Steely.Mark Sent: Thursday, July 12, 2018 1:30 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: SPOOL Volumes We are z/OS v2.2. During a DR exercise most times a cold start is performed for JES2. I noticed that a volume (that is currently online but not currently used by JES2 in production) was discovered and put into use by the JES2 cold start. This was not a problem at DR but is there a way to specify not to allocate this volume during the cold start. I know I could vary the volume offline , or rename the dataset on the volume or rename the volume. Any other ways to do this. Thank You Mark Steely AAA - Auto Club Enterprises.
