Field Name Description
Parameter Code This field contains the Flag code. See Table 5-26 for the supported
Flags, level of severity, and the Flags’ definitions.
Parameter Length This field is set to 1.
Value of Tape Alert Flag If Bit 0 is set to 1, this indicates that TapeAlert has sensed a problem.
See Table 5-26 for the supported Flags and their definitions. If Bit 0 is 0,
the Flag is not set and no problem has been sensed.
For definitions of bits that make up the Control Byte (the byte “5n + 1” above),
refer to Section 5.8.3, Table 5-21.
