ExLM Best Practices
■
Locating Physical Tape Cartridges
Many ExLM users generate an Index report using the Report Volume function
as a reference file on a workstation. This report, usually sorted by Dataset
Name (DSN), includes the volume serial number, generation number, the HSC
cell location and slot information.
For example:
ExLM has added an SL8500Cell field that provides the necessary translation to
locate cartridges.
■
Changing Configurations
The overall ExLM configuration for a SL8500 basically consists of two
components, the placement of tape drives and the placement of tape volumes.
If after a period of running and gathering data with a specific configuration it is
determined that another configuration may provide better performance, moving
to that new configuration is fairly simple with ExLM.
•
Placement of volumes with ExLM is a function of the control statements and
options selected for the ExLM management run.
•
Change the control statements and options for the new configurations.
•
During the next run, ExLM moves the volumes into the new configuration.
•
Because this could be a robotic intensive activity, execute this change
during a slow production period.
•
If necessary, relocate the physical location of the tape drives to match the
tape volumes and configuration.
