As far as I know, If you do not specify a UNIT Type, it will look for volumes that are STORAGE. If there aren't any, the allocation will fail.

Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] I have a program in Rexx that allocates a dataset using dsname and volume serial (1) . it works well in my shop but requires a unit type (2) in another shop. Actually the error is msg "IKJ56241I SPECIFIED UNIT IS UNDEFINED". Why does 1 work here and fails in another shop? 1. ALLOC F(XXX) DA('dsname') VOLUME(volser) 2. ALLOC F(XXX) DA('dsname') VOLUME(volser) UNIT(390) ITschak ITschak Mugzach *|** IronSphere Platform* *|* *Information Security Continuous Monitoring for z/OS, x/Linux & IBM I **| z/VM coming soon * ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
