Nomadic Disk Manager Configuration Statements
Examples
The following example specifies that the FUP utility should run in processor 3 with a
priority of 151:
PROCESS FUP CPU 3, PRI 151
Special Note on Parallel Processing
Because FUP and SWCI perform processing sequentially, each of these utilities needs
only a single process statement. If the configuration file contains multiple syntactically
correct PROCESS statements for any of these utilities, the last one for that utility is the
one that is used. SCF can perform commands in parallel if multiple SCF processes are
configured by issuing multiple PROCESS statements for each of these utilities.
Therefore, you might be able to improve performance by configuring several instances
of these utilities.
Parallel Processing Considerations for SCF
•
You can configure up to eight SCF processes.
•
If no SCF processes are defined, then one is assumed.
•
The maximum number of concurrent SCF commands is equal to the largest number
of disk volumes in any Nomadic Disk segment. This is also the maximum number
of useful SCF processes. The Nomadic Disk Manager must manage an entire
segment completely before it moves on to the next segment. If one segment has five
volumes, then five SCF START DISK commands must be issued and completed
before the Nomadic Disk Manager goes on to the next segment.
