The following parameters can be fine-tuned for better system
performance:

Reallocate

Drives Drive allocation is affected by the following sets parameters:
•Drive deallocation.
The deallocation parameters determine when a drive is
taken offline because of access errors. Drive
deallocation parameters are set by modifying the
appropriate system parameters. The system parameter file,
fs_sysparm, is located in the $FS_HOME/sysparms
directory.
•Delayed dismount.
The delayed dismount parameters determine when media is
dismounted from a drive after a store or retrieve request is
processed. The delayed dismount feature allows
optimization of reallocation of media for another request in
the queue and, thus, can reduce mount/dismount time for
resource requests.
Step 1. Using a text editor, open the fs_sysparm file
located in the $FS_HOME/sysparms directory.
