Mike:
Well, now I have waited the required hours and have managed to reconfigure the
entire shark for z/OS use. Thanks for your timely suggestion that I needed to
undefine the disk groups from the Open System. That was the magic step.
Thanks again.

It takes HOURS for the individual DDMs to be erased. Have you waited
the required HOURS?
Once the DDMs are erased, they should become visible through the S/390
screen, not until then. I did a session where I took very terse notes
on every click and key stroke. Oh, and wait for the boxes to go away
and make sure your displays get refreshed before proceeding with the
next step.
3. LCU (LOGICAL CONTROL UNITS)
THIS IS THE POINT WHERE YOU CAN CHOOSE TO ADD A 8-PACK TO AN
EXISTING LOGICAL CONTROL UNIT OR CREATE A NEW LCU
REVIEW LIST
CLICK ON LINE UNDER SSID WITH BLANKS TO ADD LCU *OR*
CLICK ON LINE WITH PAV DISABLED TO ADD PAV
CLICK ON CONFIGURE LCU
SELECT EMULATION MODE (3390-6)
TYPE SUBSYSTEM ID (EXAMPLE A200, A300, A400, ...)
SELECT PAV ENABLED
SELECT HIGHEST PAV ADDRESS BASED ON NUMBER OF REAL UCBS
(NUMBER SHOULD BE AT LEAST 1 PAV PER UCB)
CLICK ON PERFORM CONFIGURATION UPDATE
4. DISK GROUP
SELECT LINES UNDER STORAGE SUMMARY WITH DISK GROUP AVAILABLE
AND WITH A SS ID THAT IS NOT BLANKS
CLICK ON CONFIGURE DISK GROUPS
SELECT LINES UNDER TRACK FORMAT WITH BLANKS
SELECT STORAGE TYPE RAID-5
SELECT TRACK TYPE 3390 (3390 MODE)
CLICK ON CONFIGURATION UPDATE
5. ADD VOLUMES (CAUTION: CHANGE, DELETE IS VERY HARD)
(18GB 6/8-PACKS = 12 3390-9 + 2058 = 122,275 CYLINDERS)
(36GB 6/8-PACKS = 24 3390-9 + 4158 = 244,591 CYLINDERS)
(72GB 6/8-PACKS = 48 3390-9 + 8352 = 489,217 CYLINDERS)
(72GB 7/8-PACKS = 56 3390-9 + 9727 = 570,735 CYLINDERS)
SELECT LINES WITH FREE SPACE HAVING MOVE THAN 0 CYLINDERS AVAILABLE
CLICK ON ADD VOLUMES
SELECT LINE RAID-5 3390
32760 CYLINDERS IS MOD 27 (29.4 * MOD 1)
10017 CYLINDERS IS MOD 9 (9 * MOD 1)
3339 CYLINDERS IS MOD 3 (3 * MOD 1)
PUT IN NUMBER VOLUMES TO ADD
CLICK ON ADD TO CHANGE LIST
REPEAT FOR MORE VOLUMES AS NEEDED
CLICK PERFORM CONFIG UPDATE TO POST NEW VOLUMES
(TO DELETE THESE CHANGES, DELETE LCU WHICH WILL DELETE ALL
VOLUMES ON THIS LCU)
6. PAV PARALLEL ACCESS VOLUMES
SELECT LINES WITH DEVICE COUNTS NOT MATCHING THE
BASE AND ALIAS COUNT DESIRED FOR LCU
CLICK ON CONFIGURE PAV
SELECT VOLUMES MOST CYLINDERS TO LEAST CYLINDERS
SELECT UNTIL DESIRED PAV COUNT REACHED OR 1 PER BASE REACHED.
CLICK ON PERFORM CONFIGURATION UPDATE.
REPEAT IF CHANGES TO PAV COUNT DESIRED.
