We were using 3592E tape drives on Dynam T r7.0 with density 08E. After upgrading to r7.1, we get CADT002I *NON-COMPAT* or messages.

Issue/Introduction

 

Some datasets were defined with DENSITY=08E and with 7.0 Dynam T these datasets were written successfully to 3592E tape drives as density=08E. After upgrading to 7.1 however, tapes are read in, but output to a scratch gets CADT002I *NON-COMPAT*.

Added new 3592 C06 drives also

Resolution

The existing density may not be recognized on release 7.1 if the DYNAM catalog, CAICATL, was reorganized when upgraded from r7.0 to r7.1. Such a REORG, with the DYNCAT utility, or if the DTOPTION MTCHMOD is set to YES.

Four new density specifications can be used to specify that a CA Dynam/T controlled dataset should be written to a 3592E tape device. The four new densities are: 00WE, 08WE, 20WE, and 28WE. The new density values can be specified either when defining or altering a dataset using DYNCAT, or on the TLBL at JCL time.

Note as well, that if encryption support is available, IBM has added four new modes to indicate a file should be encrypted when written to tape. Accordingly four new densities have been added to Dynam which, when specified, indicate that a particular dataset should be encrypted when written to tape. The four new Dynam/T densities to indicate tape encryption are 03WE, 0BWE, 23WE and 2BWE.

If you are using 3592 C06 then you should use 08W6 for density definition.

Note that IBM maintenance may affect how devices are recognized by z/VSE.
