When configuring a Disk Storage Server, the statistics fields (Total Virtual Volumes, Total Allocated
Volumes, Total Bytes, Used Bytes, and Free Bytes) in the Storage Server Configuration window will
not be displayed. These fields cannot be set for Disk Storage Servers because the server computes
these values each time it initializes and does not use the fields in the specific configuration record.
When configuring a Tape Storage Server, the initial values of the statistics fields are normally zero,
but other values can be used. The server reads the configuration record when it initializes and
updates the record as the statistics change. For this reason, SSM will not allow changes to be made
to the Storage Server specific configuration while the server is running. Adjustments can only be
made to the statistics by modifying the statistics fields when the server is not running.
The best way to set the initial values of the tape statistics is to use the settapestats utility program.
After all of the tapes have been created in a tape storage server, take the server down and run
settapestats with the update_both option. All of the statistics will be calculated and stored in the
tape storage servermetadata. See Section12.2.56: settapestats —Compute Tape StorageServer Statistics
on page 469 of the HPSS Management Guide for details.
