MQSeries.net :: View topic - CSQUTIL for MQ V531 on MAINFRAME, problem

We have Z/OS 1.4, MQ V531.

What we want to do is create a PSID as a multi volume dataset.
To prevent dynamic expansion of the dataset we decided to expand the dataset on a test MQ, and then use the CSQUTIL with options FORMAT, FORCE, PAGES(1043574) TYPE(NEW). The documentation implies that this should work and you can then start up this formatted PSID on a different MQ. The problem we are having is that we receive a VSAM error on the job as follows.
1)
DEFINE CLUSTER -
(NAME(SYS3.CSQ.MQCT.PSID02) -
RECORDS(600000 10000) -
LINEAR -
REUSE -
VOLUMES(PMQSC4 PMQSC5 PMQSC3) -
SHAREOPTIONS(2 3) ) -
DATA -
(NAME(SYS3.CSQ.MQCT.PSID02.DATA) )
2)
//FORM EXEC PGM=CSQUTIL
//STEPLIB DD DSN=SYS1.MQM.SCSQSNLE,DISP=SHR
// DD DSN=SYS1.MQM.SCSQANLE,DISP=SHR
// DD DSN=SYS1.MQM.SCSQAUTH,DISP=SHR
//CSQP0002 DD DISP=OLD,DSN=SYS3.CSQ.MQCT.PSID02
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
FORMAT

3) We then start up MQ populate the PSID02 to its maximum, so now its on 1043574 pages, and we get MQ errors on trying to put extra messages. With our version we can only go to 4gb PSIDs. We stop the MQ.

4) We then run the following against the PSID
//FORMAT EXEC PGM=CSQUTIL
//STEPLIB DD DSN=SYS1.MQM.SCSQSNLE,DISP=SHR
// DD DSN=SYS1.MQM.SCSQANLE,DISP=SHR
// DD DSN=SYS1.MQM.SCSQAUTH,DISP=SHR
//CSQP0002 DD DISP=OLD,DSN=SYS3.CSQ.MQCT.PSID02
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
FORMAT FORCE PAGES(1043574) TYPE(NEW)

5)Which fails with

IEC070I 034-204,BQIXA04#,FORMAT,CSQP0002,13D1,PMQSC4,

CSQU144I 0 FORMAT statements executed successfully
CSQU148I CSQUTIL Utility completed, return code=8

The errors seem to imply VSAM could not allocate additional space to make the secondary allocation. When you check the dataset its obviously still a multi volume dataset, but only occupies the first volume, nothing on the second volume.

We have seen comments that say you can pre-format page sets to prevent dynamic page set expansion using the CSQUTIL Format command to push over to another volume by using the pages option, which we have done.
Question, has anyone else come across this problem, are we using the correct Format parameters?
Thanks in advance for any help or suggestions.
