TAPE-DAT (Tape Consistency)
In High and Critical Reliability systems, the system software translations, as well
as other information, can be stored on two tapes: one in the Active SPE and one
in the Standby SPE. In order to flag a problem when these tapes become
mismatched, Tape Consistency monitors the translations, announcements,
update files, and software vintage number on both tapes in a High or Critical
Reliability PPN system. If the translation time stamp, announcement time stamp,
and update file time stamp and identifiers on the two tapes are not the same
and/or if the software vintage numbers do not match, an alarm is raised. The
software vintage can be displayed via the list configuration software-vintage
command. The Tape Consistency Test is run on system technician command and
once a week as part of daily Standby SPE maintenance. Tape Consistency does
not apply and does not exist in Standard systems.
