Subject: Scan for shared volume
Hi Takako,
There we many changes between 7.5 and 8.2 and one of them was the addition on mirroring. By the way this has now been replaced by PTF UJ92779. The customer is running old code and needs to apply a lot of maint. That being said. The problem we thought originally was that the Inquisitor code that scans the volumes was in error but now that is not the case. At some point in time the DASD was imported from LPAR SYSD for the library X6.LOADLIB and that means that SYSD is deemed to be the owner of that library. IT can only ever be updated by SYSD. Now I can't tell what has transpired in 8.2 because now there is another library that has been imported from another LPAR because as you say the DASD is shared but clearly SYSD matched X6.LOADLIB first and then the second LPAR added X6.T.LOADLIB. So at some point in time this library was not scanned by SYSD.
Question: How is this data being scanned? Was PLX=Y/N used and if so which one? If you have used PLX=Y then the assumption is that ALL the DASD is shared between all LPARS. Is that the case? If it is then make sure all the latest maint is applied and then run IQIMPORT again and the issue will be resolved. It is important to keep up to date with maint. If there are other issues then please open a case.
Regards
Jim K.

Greg,
Thank you for your help.
When scanning using V7.5, both datasets are scanned as follows.
Full rematch will be performed because the FULLREMATCH option is set
libid VOLSER Library Status
====== ============================================ ====================
1 IP0002 X6.LOADLIB Added
2 IP0002 X6.T.LOADLIB Added
But as scanning using V8.2, one dataset has the status as Mirror dataset as follows.
=================================Start of Marked as deleted library list==============================
libid library name volume status action
===== ============ ====== ========== =============
8 X6.LOADLIB IP0002 Mirror(base= SYSD)Deleted
222 X6.T.LOADLIB IP0002 Base Deleted
We make sure FOBSERVELAST column for X6.LOADLIB in XRD02B.TMODULE was not updated, so we think this dataset cannot be scanned but there is no error message.
Would you give me any suggestion?
Sincerely,

Hi,
Please help to scan for shared volume.
When we scan two load libraries, one dataset cannot be scanned. They are allocated on the same volume and the volume is shared by two systems.
Our customer has just upgraded from V7.5 to V8.2.
When we use the same parameter to scan in V7.5 environment and V8.2. V7.5 can scan both libraries and V8.1 cannot work; only one library can scanned.
We're thinking that the scanning function's specification was changed between V7.5 and V8, so we think it would be corrected when we just specify PLX=Y. Is it right?
Also please tell me if there is any other consideration to scan for shared datasets?
Thanks in advance,
