Hi, we just migrate to z/OS 1.8 last sunday and now we have problems with panel Generate a list of storage groups in ISMF because in the column MB Free Space and % Free Space appears << (the value is greater than 1) however when I list the volumes displays all data with the information.
| Code: |
LINE STORGRP MB TOTAL MB FREE % FREE LAST MOD
OPERATOR NAME SPACE SPACE SPACE USERID
--(1)---- --(2)--- --(14)--- --(15)--- -(16)- --(17)--
BDVTRAN 277270 163384 58 SOP014

LINE VOLUME FREE % ALLOC
OPERATOR SERIAL SPACE FREE SPACE

Hello,
Possibly because there is no media in the drive, so no statistics can be reported? |

The pools that no show the free space value are disk pools:
| Code: |
LINE STORGRP MB TOTAL MB FREE % FREE LAST MOD
OPERATOR NAME SPACE SPACE SPACE USERID
---(1)---- --(2)--- --(14)--- --(15)--- -(16)- --(17)--
BDVTRAN 277270 162976 58 SOP014
listv DISKEXT1 --------- <<<<<<<<< << SOP014
DISKEXT2 --------- <<<<<<<<< << SOP014
DISKEXT3 8120 4713 58 SOP014 |
For example when we list volumes of pool DISKEXT1 we can see all the values without problem:
| Code: |
LINE VOLUME FREE % ALLOC FRAG LARGEST
OPERATOR SERIAL SPACE FREE SPACE INDEX EXTENT
---(1)---- -(2)-- ---(3)--- (4)- ---(5)--- -(6)- ---(7)---

| In my experience this is because no allocations have occurred in the pool since it was created, or since the last IPL, so ISMF doesn't refresh the info. Sometimes a temp allocation to the pools sorts it out. |

Thanks Pete,
It is true, the pools with problems are updated constantly but no new files created in them, after create a small test file MB Free Space and % Free Space columns were updated with the right values, the problem was solved. |
