Chris, Others have made good suggestions. Over time, you may have more DASD that you want to dump or use multiple virtual machines that you want to use simultaniously to dump from. Here is one way to address that: Define one dummy user that owns a full pack minidisk on each volume: USER $VOLS$ NOLOG ACCOUNT SYSTEM SYSTEM MDISK A00 3390 0000 3339 VOLA00 RR MDISK A01 3390 0000 3339 VOLA01 RR MDISK A02 3390 0000 3339 VOLA02 RR MDISK A03 3390 0000 3339 VOLA03 RR MDISK A04 3390 0000 3339 VOLA04 RR Now define multiple dump users that do the dumping to tape. These users will have access to the dummy account disks above. To make it simpler, just define a user profile first then use that in each dump account: PROFILE SYSDMPPR * Profile for SYSDUMP users ACCOUNT SYSUTIL SYSTEM MACHINE XC IPL CMS PARM AUTOCR CONSOLE 009 3215 SPOOL 00C 2540 READER * SPOOL 00D 2540 PUNCH A SPOOL 00E 1403 A LINK MAINT 190 190 RR LINK MAINT 19E 19E RR LINK $VOLS$ A00 A00 RR LINK $VOLS$ A01 A01 RR LINK $VOLS$ A02 A02 RR LINK $VOLS$ A03 A03 RR LINK $VOLS$ A04 A04 RR Now each new dump account can be define using: USER SYSDUMP PASSWORD 5M 25M G INCLUDE SYSDMPPR MDISK 191 3390 xxxx yyyy zzzzzz W * USER SYSDUMP2 PASSWORD 5M 25M G INCLUDE SYSDMPPR MDISK 191 3390 xxxx yyyy zzzzzz W Now each dump account has a virtual address that matches the real address of a real DASD. You can then do a DDR with input statements that point to the virtual address. Remember to never make this LINK or MDISK statements in write mode. Everything should be in read only mode. Aria
