This parameter defines flags for cpio commands that the SAP tools use for reading files from a tape volume.
cpio_in_flags = <flags>
Default value: -iuvB
The flag B causes a block size of 5 KB to be used. You can also use a higher block size, such as 64 KB (if cpio permits this for your hardware platform), to increase performance when reading from tape.
The block size in cpio_flags and cpio_in_flags must be the same.
