Problem:
Happens at restore, for example during a verify of an RMAN backup.

Cause:
The backup Server positions the Tape onto the beginning of save File in 2 process steps
skip File marks up to the last File mark before the savefile begins.
skip records from the last File mark up to the beginning of the savefile.
If the number of records to be skipped is larger than an OS and firmware dependent threshold, the record skipping must be done in multiple smaller hops.
Solution:
The Hiback configuration to achieve this in the multiplexer-config File is
max-skip-records: 100000
The Hiback configuration to achieve this in the hiserv device string is
$[node]*al|||spm=100000
This limits the separate hop length to 100000 records each.
