Because the 3592-2E can write in three recording formats (EFMT1, EFMT2 or EEFMT2), you must modify your installation's ACS routines to select the recording format to be used on empty media (through the data class assigned to the tape) if you want the 3592-2E drives to use EFMT1 or EEFMT2.

For duplexed tapes, ensure that the data class selects the same media type and recording technology for the original and the alternate copy. Not doing so can result in failure when the duplex tape is mounted for output, or when using the alternate copy after a tape replace. If different media or machine types are needed for the original and alternate tapes, see APARs OW52309, OA04821, and OA11603 for more information.
