Configurations Supported; Code Requirements - IBM TS7700 Series User Manual

August 15, 2017
• Copy export hold volumes can be moved back into the source TS7700 without ejecting them first.
• Version 2.3
• For release code level R3.2 or higher, introduction of TS7720 Tape Attached (TS7720T)
• For release code level R3.2 or higher, add caution for applying Time Delayed Premigration to
logical volumes whose secondary pool is copy export pool.
• For release code level R3.2 or higher, Offsite Reclaim acceleration.
• For release code level R3.3 or higher, customers that have E08 drives can choose to write copy
export physical volumes in either 3592 E07 or E08 recording format.
• For release code level R3.3 or higher, TS7700 supports heterogeneous E08 drive environments and
Copy Export comes to support exporting different recording format physical volumes at one time.
• Version 2.4
• For release code level R3.3 or higher, with the introduction of the JD media, the tape capacity can
exceed 7 characters. There is a change in the Export Status File Records. The "Total Bytes Written"
in the physical export volume record expanded from bytes 15-21 to bytes 15-22. Subsequently, all
fields after the "Total Bytes Written" are shifted down by 1 byte. The total length of the physical
export volume record remains unchanged at 80 bytes.

Configurations Supported

The Copy Export function is supported on all configurations of the TS7700, including Grid configurations.
In a Grid configuration, each TS7700 is considered a separate source TS7700. This means that only the
physical volume exported from a source TS7700 can be used for recovery of a source TS7700. Physical
volumes from more than one source TS7700 in a Grid configuration cannot be combined to use in recovery.
Recovery is only to a single cluster configuration. The TS7700 used for recovery must be configured as
cluster 0. After recovery, the grid MES offering can be applied to recreate a Grid configuration.
To perform a copy export operation, the TS7700 must have a minimum of four available physical tape
drives.

Code Requirements

The Copy Export function for standalone configurations was introduced with TS7700 code level 8.3.x.x and
library manager code level 535.x. For Grid configurations, the copy export function was introduced with
TS7700 code level 8.4.x.x. Although there are no host software updates required to support the copy export
function, there are other functions supported in the TS7700 that do require a later level of host software for
support. One of those, host console request, does require z/OS support and that is provided at z/OS V1R6
and above. Refer to OAM APAR OA20065 and device services APARs OA20066, OA20067 and
OA20313.
For the changes supported in version 1.2 of this white paper, the minimum code level for the TS7700 is
8.4.1.37.
For the changes supported in version 1.3 of this white paper, the minimum code level for the TS7700 is
8.4.1.57.
For the changes supported in version 1.4 of this white paper, the minimum code level for the TS7700 is
8.5.x.x and library manager code level 536.x for systems that have a 3494 library attachment.
