10-1612 Issue 4 May 2002
In a High or Critical Reliability system, if an alarm is raised against the Tape Unit,
the alarm also indicates the carrier (either 1A or 1B), depending on which SPE
has the problem.
NOTE:
CLEANING THE TAPE DRIVE HEAD IS VERY IMPORTANT because a
tape drive head with abrasive particles can permanently damage a new
tape. In addition, a worn tape may leave abrasive particles in the tape drive
head. Before implementing any of the following repair procedures, the tape
head of all the tape drive units in the system should be cleaned. Follow the
directions given in the ‘‘Tape Drive Head Cleaning Procedure’’ section.
