Hi There are no error messages as we have not defined the new dataset yet. I was just wondring why a second volume was not used as I think it should.
The dataclass is pretty basic: Every thing blank except for: Data Set Name Type . . . . . : EXTENDED If Extended . . . . . . . . : PREFERRED Extended Addressability . . : YES Record Access Bias . . . . : USER Space Constraint Relief . . . : NO Reuse . . . . . . . . . . . : NO Initial Load . . . . . . . . : RECOVERY BWO . . . . . . . . . . . . : Log . . . . . . . . . . . . : Logstream Id . . . . . . . . : FRlog . . . . . . . . . . . : RLS CF Cache Value . . . . . : ALL RLS Above the 2-GB Bar . . . : NO Extent Constraint Removal . : NO But if VSAM tries to use primary space and there are no empty volumes in the storagegroup I guess thats explains why there is no extends. Primary space was defines as 12000 cyls........
