2. Backup DB.

3. Mount each tape in the copy export pool and copy the DB to the tail end.

4. Eject the tapes or move them to copy export hold.

5. Finish out the export list volume with status.

In 8.21.x.x or higher, there is a new option available to limit the number of export cartridges that will

contain a database backup. The customer can set the new option on the Copy Export List volume. If

this option is set, the database backup will be appended to the first two export tapes and the last two

export tapes. Any one of the four tapes containing the backup can be used for disaster recovery of the

pool. The export process is sped up because only a maximum of four of the export tapes are remounted

to append the backup database.

27. If the customer has feature code 5273 Enable Tape Attach installed on TS7720 whose code level is

8.32.x.x, it comes to be TS7720 Tape Attach (TS7720T). TS7720T can perform copy export operation.

28. Both TS7740 and TS7720T can perform copy export operation. At copy export recovery, the copy

export sets can be used to restore data at a location that has equal or newer physical tape drive and equal

or newer TS7700 microcode. TS7720T copy export set can be restored into both TS7740 and TS7720T.

TS7740 copy export set also can be restored into a both TS7740 and TS7720T.

29. If the logical volumes are assigned to CP0 in TS7720T, the logical volumes are resident only and never

copied to any physical volumes. Hence, logical volumes in CP0 can’t be exported.

30. When using the Copy Export acceleration (LMTDBPVL) option, the database backup is appended only

to the first two and the last two volumes that are exported. These corresponding tapes with the database

backup are selected and listed in the alphabetical order of the physical tape VOLSER. If the

LMTDBPVL option was set, and there is a failure appending the DB backup, a different physical

volume is selected to contain the database backup so that four physical volumes have the DB backup.

31. The Copy Export operation might fail depending on the combination of installed tape drives, media

types, or recording formats of physical volumes in the secondary pool, and the existence of

LMTDBPVL option. Exportable physical volumes are explained in detail in the table below. If

unexportable physical volumes are included in the Copy Export set physical volumes, the Copy Export

operation fails and returns message CBR3856I
