Sounds about right. Doing the math (roughly) at 2.8 gb/volume (3390 mod3). Non extended VSAM has a upper limit of 4gb
2.8GB 3339(cyl) ___ = ________ 4.0GB x(cyl) 2.8x = 4*3339 X=4770 cyls. Allowing for VTOC, VTOCIX, VSAM overhead, INDEX, CISIZE,.... I would accept 4350 as reasonable . You might try to map the volumes and see if the VVDS is in the "middle" of the pack... HTH, <snip> What is the maximum number of cyclinders that can be used to define a dsn that is not VSAM EXTENDED. I think it is 4400 cylinders. I was trying to allocate a dsn at 4500 4500 but I kept on abending with IGD17273I ALLOCATION HAS FAILED FOR ALL VOLUMES........ Finally I was able to allocate the dsn at CYL(4350 4350). </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
