Whenconfiguring aDiskStorage Server,the statisticsfields(Total VirtualVolumes,TotalAllocated
Volumes, TotalBytes,UsedBytes,andFreeBytes)in theStorage ServerConfiguration windowwill
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 configuringa Tape Storage Server, the initialvalues of thestatistics fields are normally zero,
but other values can be used. The server reads the configuration record when it initializes and
updates therecord as thestatistics change. For this reason, SSM willnot allow changes to bemade
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
tapestorageservermetadata.SeeSection12.2.56:settapestats—ComputeTapeStorageServerStatistics
on page 469 of the HPSS Management Guide for details.
