Hi,

I want create a rexx program which i can calculate number of cylinders to use in my vsam when the number of cylinders is found, I want to search a disk to use for my DBD. These disks are listed in a member.

If your DASD is SMS managed the chances are that your DASD selection will be ignored anyway, so that removes that problem.

When you say DBD is this a DB2 dataset ?[/Search]

No it 's a DBD DL/I, no Db2.

So, we don't use sms for managed disk. We must give a disk for each DBD.

Actually, we must found in a list (of disk), a disk with numbers cylinders use for a DBD.

If i calculate (I want a rexx program to calculate) 150 cylinders for a DBD, I must found a disk free with 150 cylinders.
Our disks are shared in several clients.
