[. . . ] The SCSI command with CHECK CONDITION completes without error prior to the report of any exception condition, and does not need to be repeated. CHECK CONDITION status on the next SCSI command (except INQUIRY and REQUEST SENSE commands) reports information exception conditions by returning 58 SuperLoader 3 Software Interface Guide Chapter 2 Media Changer Commands Mode Sense (6) / (10) Command (1Ah/ 5Ah) Field Name Description 06h Only Report Informational Exception Condition on Request. To access the data, a poll can be taken by issuing an unsolicited REQUEST SENSE command. The Sense Key is set to NO SENSE with an additional sense code of 5D 00 (TapeAlert Event). The additional sense code of 5D 00 for values 03h, 04h, and 06h signals that a TapeAlert event has occurred. The setting of MRIE does not impact logging of events in the TapeAlert Log Page. Interval Timer Report Count/Test Flag Number Not supported. Report Count or Test Flag Number. When the Test bit is set, this field indicates that a test condition to be generated as follows: Value 0 Result Change no TapeAlert Flag but report an exception condition based on the setting of the MRIE field. Set the TapeAlert Flag indicated in the value and generate an exception condition based on the MRIE field. Clear the TapeAlert Flag in an equivalent manner to taking corrective action of indicated by the absolute number of the value. Set all TapeAlert Flags and generate and exception condition based on the setting of the MRIE field. 1 to 64 -1 to -64 32767 Element Address Assignment Page2 The element address assignment page is used to report element address assignments to the host. None of the fields in this page are changeable.

Defines the total number of storage elements contained in the media changer. There are 16 total, although since the magazines are removable, eight of them may be "inaccessible" at times. Identifies the address of the first import/export element that is accessible both by the medium transport device and also by an operator from outside the media changer. Defines the total number of import/export elements contained in the media changer.

Defines the total number of data transport elements contained in the media changer. The SuperLoader 3 contains 1. Transport Geometry Parameters Page 2 The transport geometry parameters page defines whether each medium transport element of a media changer is a member of a set of elements that share a common robotics subsystem and whether the element is capable of media rotation. One transport geometry descriptor is transferred for each medium transport element, beginning with the first medium transport element. None of the fields in the page are changeable.
