Gilbert, What type of dataset? PS or VSAM? If the primary and secondary quantity of the dataset was defined such that (primary + (n*secondary) * 3 or higher) is required for the dataset, (where n = 16 for PS and 121 for DB2 VSAM) then the allocation amounts will have to be modified to ensure that the dataset can be contained on only 2 volumes.

Background: We recently added more storage to our Shark and we initialized all of the new volumes as Mod 27s. I migrated several storage pool volumes to the new mod 27s so some of the storage pools went from 10 volumes per say to 2 volumes. Observations: We ran into an issue this weekend where one of our DB2 jobs abended with a IEC028I 837-08 error code. From all indications there was plenty of space available but after looking at the control cards, the jcl was specifying a volume count of 5 but there were only 2 volumes in the pool available. It was my understanding that specifying a volume count would only allow the job to utilize that many volumes if they were available. Not that that many volumes would be a requirement. Questions: Would jcl that is specifying a volume count more than what is available cause this type of abend? Are there other gotchas I need to look out for? Can anyone shed some light on this?
