As Gerhard pointed out in an earlier post, the 3rd byte of the 4 bytes of device type info are documented in the UCB macro in the field UCBTBYT3, where X'80' denotes a tape device (which corresponds to HSM level 2) and X'20' denotes a direct access device (which corresponds to HSM level 1).

For HSM, a migrated data set has serial of MIGRAT, then third byte of x'20' for level 1, and 'x80' for level 2. IIRC, similar information is available from IDCAMS DCOLLECT. ---------------------------------------------------------------------- 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
