tape_size_arch 

This is the tape size in gigabytes (G), megabytes (M) or kilobytes (K) used by BRARCHIVE. This parameter should be used if different tape stations are addressed with parameters tape_address_arch and tape_address_rew_arch than with tape_address and tape_address_rew. Different tape station types can then be used for BRBACKUP and BRARCHIVE without risking a tape overflow.

Syntax: tape_size_arch = <size>K|<size>M|<size>G

Default: the value set in tape_size
