GLYPH<SM590000> If a scratch physical volume is needed during a Copy Export operation, the secondary  physical volume pool must include an available scratch volume or access to borrow one for  the operation to continue. If a scratch volume is not available, the TS7700 indicates this  issue through a console message, and waits for up to 60 minutes. If a scratch volume is  not made available to the secondary physical volume pool within 60 minutes, the Copy  Export operation is ended. GLYPH<SM590000> During execution, if the TS7700 determines that a physical volume that is assigned to the  specified secondary pool contains one or more primary logical volumes, that physical  volume and any secondary logical volumes on it are excluded from the Copy Export  operation. GLYPH<SM590000> To minimize the number of physical volumes that are used for Copy Export, use the  highest capacity media and physical drive format that is compatible with the recovery  TS7700. You might also want to reduce the number of concurrent tape devices that the  TS7700 uses when copying data from cache to the physical volumes in secondary pool  that is used for Copy Export. You can change it by using the Maximum Devices in Pool  Properties in the MI. GLYPH<SM590000> All copy-exported volumes that are exported from a source TS7700 must be placed in a  library for recovery. The source TS7700 limits the number of physical volumes that can be  Copy Exported. The default limit is 2000 per TS7700 to ensure that they all fit into the  receiving library. This value can be adjusted to a maximum of 10,000 volumes by using  Copy Export Settings in MI. GLYPH<SM590000> The recovery TS7700 must have physical tape drives that can read the physical volumes  from a source TS7700. If a source TS7700 writes the volumes by using the native E08  format, the recovery TS7700 must also have 3592-E08 drives running in native format  mode. If a source TS7700 writes the JB volumes by using the native E07 format, the  recovery TS7700 must also have 3592-E07 drives. If a source TS7700 writes the JC or JK  volumes by using the native E07 format, the recovery TS7700 must have 3592-E07 or E08  drives.  GLYPH<SM590000> An available service offering that is called Copy Export Merge allows a customer to merge  data from more than one source TS7700 Copy Export backup. However, the recovery  TS7700 cannot contain any previous data, and a client-started recovery process cannot  merge data from more than one source TS7700. As a part of the Copy Export Recovery,  an option is provided to erase any previous data on the TS7700. This process enables a  TS7700 that is used for disaster recovery testing to be reused for testing of a different  source TS7700’s data. GLYPH<SM590000> For the secondary pool that is used for Copy Export, the designated reclaim pool must not  be the same pool as the primary pool or its reclaim pool.  If the exporting pool on the source TS7700 is set up to encrypt the data, the recovery  TS7700 must also be set up to handle encrypted volumes and have access to the IBM  Encryption Key Manager with replicated keys from the production site. If the source  TS7700 writes the volumes in J1A or emulated J1A mode, the recovery TS7700 must  have 3592-E07 or the previous generations 3592 model drives. Note:  If the reclaim pool for the Copy Export pool is the same as the Copy Export  primary pool or its reclaim pool, the primary and backup copies of a logical volume can  exist on the same physical tape.
