Selection of a diagnostic routine is accomplished by assigning a routine's corresponding Execute
Count byte a non-zero value. Routines 50 to 57 are diagnostic specific to the Tape Drive logical
unit, and routines C0 and C2 are specific to the Medium Changer logical unit. Therefore, if the
Tape Drive logical unit is selected, only the Execute Count bytes corresponding to the Selftest rou-
tine (Routine 01) and routines 50 to 57 may have non-zero values. Bytes 1, 10-11, and 13-19 must
be zero; otherwise a CHECK CONDITION is returned with Sense Key set to ILLEGAL
REQUEST and Additional Sense Key set to INVALID FIELD IN PARAMETER LIST. Con-
versely, if the Medium Changer logical unit has been selected, only the Execute Count bytes corre-
sponding to routine C0 and/or C2 may have non-zero values. Bytes 1, 4-12, and 15-19 must be
zero; otherwise a CHECK CONDITION is returned with Sense Key set to ILLEGAL REQUEST
and Additional Sense Key set to INVALID FIELD IN PARAMETER LIST.
Selection of routines 50 and 51 do not require either DevOfl or UnitOfl to be set. Selection of rou-
tines 52 to 57, or C0 to C2 require both DevOfl and UnitOfl to be set. If a parameter list is received
by the controller which indicates selection of any of the routines 52 to 57, or C0 and/or C2, and
both UnitOfl and DevOfl are not set, a CHECK CONDITION is returned with Sense Key set to
ILLEGAL REQUEST and Additional Sense Key is set to INVALID FIELD IN PARAMETER
LIST.
If any error condition is encountered during execution of a routine, diagnostic result data is gener-
ated at that time and no further diagnostic execution occurs.
