To direct an allocation to a specific SMS volume, the Storclass will need to have Guaranteed space = YES. If the allocation is to go to a non-SMS volume, why is Dataclas= and Storclas= in the jcl?

It seems that your ACS routines do not allow the explicit assignment of STORCLAS, or perhaps the explicit assignment of STORCLAS SC46. It further seems that VOL=SER=XXXXXX triggers SMS management of the data set, be it with the specifed STORCLAS or with one determined by the ACS routine. >Any shop using explicitly coding instead of ACS to control? We've got a need for some data sets to be EXTENDED format PS data sets which predates DSNTYPE=EXTREQ which came with z/OS V1.7. It was implemented via special volume serial number (ABCXYZ) which will be recognized by the ACS routines. Correct attributes (like DATACLAS) are then assigned. Seems similar to your VOL=SER=XXXXXX. We're also allowed to explicitly specify MGMTCLAS even though the ACS routines will assign one based on the data set name if none is specified via JCL, ISPF 3.2, etc. Peter Hunkeler Credit Suisse ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
