I don't think so. SMS is enforcing corporate policy. Either 1. The SMS routines do not accurately reflect the policy, or 2.

You are suggesting that if I specify a volume, the system should always try to use that volume and no other, even if there is no space on the volume. And if the storage administrators remove the volume from the system, your job will fail. That kind of behavior is unacceptable for a production shop. >or result in a JCL error _clearly_ describing the cause >and citing the applicable SMS rule. SMS does not have "rules" It has "routines". There are four Automatic Class Selection routines and each one makes a single decision. The Storage class ACS routine selects a storage class, for example. It does not pass back a reason for the selection, but the ACS routine is free to issue messages to help the user. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
