Hello Kris,
I use both DIRMAP and DISKMAP. For me, keeping the $END$ and $ALLOC$ in help me keep everything straight. I am sure there are other techniques that work for others.

DIRAMP knows how to properly treat fullpack minidisks, they are not taken as overlap... In my CP directories, **any** overlap signals a problem, there should be not a single one, otherwise people will miss a truely unexpected overlap too. DIRMAP even signal overlaps with a non-zero return code and message to the console, but, it ignores fullpack overlays. With DIRMAP fullpack definitions are still a very good thing, for example to learn DIRMAP how many cylinders a volume has; no need to define a dummy user $END. I sent Terry Martin the directory wisdom document I wrote for my former customer. 2009/3/12, Edward M Martin <emar...@aultman.com>: Hello Terry, As others have explained, MAINT uses these to do some functions (DDR backup etc). The overlay is normal from DISKMAP and is expected (well should be). I have added user ids of $ALLOC$ and $END$ for cylinder 0 and for the last cylinder on all z/VM volumes as a reminder for myself. Just something that helps me keep track. (No, we do not have DIRMAINT.)

In my MAINT directory entry I have the following: MDISK 122 3390 000 END 530SPL MR MDISK 123 3390 000 END 530RES MR MDISK 124 3390 000 END 530W01 MR MDISK 125 3390 000 END 530W02 MR MDISK 126 3390 000 END 530W03 MR Now, I reference these disks I other entries in the directory starting at location 001 for however many cylinders I need. As you can see the MDISK entries above start at 000 to END. The output from the DISKMAP shows the following: VOLUME USERID CUU DEVTYPE START END SIZE 530SPL $SPOOL$ B01 3390 00000 END ? MAINT 122 3390 00000 END ? *OVE 530W01 LNXADMIN 191 3390 00001 00100 00100 E49L021P 191 3390 00101 00102 00002 E49L054P 191 3390 00103 00104 00002 E49L124P 191 3390 00105 00106 00002 E49L046P 191 3390 00107 00108 00002 MAINT 124 3390 00000 END ? *OVE 530W02 E49L021P 910 3390 00001 00200 00200 E49L054P 910 3390 00201 00400 00200 E49L124P 910 3390 00401 00600 00200 E49L046P 910 3390 00801 01000 00200 MAINT 125 3390 00000 END ? *OVE I see what the problem is my question is do I need to have the entries for these disks in the MAINT directory entry? And what are the consequences if they are removed from the MAINT entry. This is the way the DIRECTORY was shipped on the install tape. Thanks for the help!
