If a source TS7700 writes the volumes using the native E05 format, then the recovery TS7700 must also
have 3592 E05 drives running in native format mode or 3592 E06/E07 drives. If the exporting pool on
the source TS7700 is set up to encrypt the data, then the recovery TS7700 must also be set up to handle
encrypted volumes and have access to the encryption key manager with replicated keys from the
production site. If the source TS7700 writes the volumes in J1A or emulated J1A mode, then any 3592
model drive in the recovery TS7700 can read the data.
21. If the copy export tapes are being used for recovery, the recovery TS7700 cannot contain any previous
data and the recovery process basically cannot merge data from more than one source TS7700 together.
However, for customers running 8.21.x.x code on an existing TS7700, a service offering is available
where a customer can merge data from a copy export backup tape into an existing TS7700 (either stand-
alone or grid). Please contact your sales team for information.
22. As a part of copy export recovery, an option is provided to erase any previous data on the TS7700. This
allows a TS7700 that is used for disaster recovery testing to be re-used for testing of different source
TS7700’s data.
23. The physical and logical volumes exported during a copy export operation are not known by the tape
management system. You can use the export status file to keep track of the volumes or use the
information to manually update tape management system records.
24. If the number of volumes recovered on the recovery TS7700 exceeds 1 million volumes, the system will
be blocked from inserting additional logical volumes until the appropriate number of 5270 feature codes
are installed. Each instance of this feature increases the number of logical volumes supported by
200,000.
25. If the customer has feature code 5271 Selective Device Access Control installed on the source TS7700,
the associated management class policies will be restored on the recovery TS7700. Feature code 5271
will need to be installed on the recovery TS7700 in order for these policies to take effect.
26. On systems running 8.21.x.x code or higher, if the customer exports a high number of volumes per pool
with each export request, they may want to consider using the copy export accelerator. When a
customer runs a LXPT request, the following sequence is performed:
1. Finish pre-migration to any volume targeted for the copy export pool.
