DDS Tape Log (page 30)
Page 30, the DDS Tape Log page, allows you to obtain the information last written
to the DDS Tape Log. Each time the cartridge is ejected the Tape Log is updated.
This log contains two types of counts:
• The Previous counts indicate events from the previous usage cycle of the
cassette. (A usage cycle is composed of a single cartridge insertion, use, and
ejection.)
• The Total counts accumulate events over the life of the cassette since the
cassette was first initialized by a format process.
When a cartridge is formatted, the total and previous counts are initialized to 0. The
previous counts in this page are updated when a previously formatted cassette is
inserted to indicate the counts from the previous usage of the tape. The previous
counts remain consistent through the usage cycle. Previous counts can be
inspected with the LOG SENSE command.
If no activity occurs during the usage cycle, then the previous counts are all set to 0
and the Load Count is incremented by 1.
