[. . . ] 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. Information about the event is stored in the TapeAlert Log Page. 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. This field must be set to 0 unless the Test bit is set. 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 Quantum PX500 Series Software Interface Guide 81 Chapter 3 Media Changer Commands Mode Sense (6) / (10) Command (1Ah/ 5Ah) Element Address Assignment Page 3 The element address assignment page is used to report element address assignments to the host. This page also defines the number of each type of element present. None of the fields in this page are changeable.

Quantum PX500 Series Software Interface Guide 82 Chapter 3 Media Changer Commands Mode Sense (6) / (10) Command (1Ah/ 5Ah) Field Name Number of Medium Transport Elements First Storage Element Address Number of Storage Elements First Import/ Export Element Address Number of Import/Export Elements First Data Transfer Element Address Number of Data Transfer Elements Description Defines the total number of medium transport elements contained in the media changer. Identifies the address of the first medium storage element contained in the media changer. Defines the total number of storage elements contained in the media changer. 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. Identifies the address of the first data transfer element contained in the media changer. Defines the total number of data transport elements contained in the media changer. Transport Geometry Parameters Page 3 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.

Table 75 Transport Geometry Descriptor Bit 7 Byte 0 1 6 5 4 3 2 1 0 Reserved Member Number In Transport Element Set Rotate Table 76 Transport Geometry Parameters Page Field Name Parameter length Rotate Member Number in Transport Element Set Description Specifies the number of bytes of transport geometry descriptors to follow. Rotation of the medium transport element is not supported. There is only one medium transport element and robotic subsystem. Device Capabilities Page 3 The device capabilities page defines characteristics of the element types of a media changer. This information may be employed by the initiator to determine functions permitted by the MOVE MEDIUM command. [. . . ] Issue a Read Element Status command and retry move command. If the problem recurs, issue an Initialize Element Status command followed by a Read Element Status command and retry Move command. 5 3B 0E MEDIUM SOURCE ELEMENT EMPTY The destination element address does not contain a cartridge. Issue a Read Element Status command and retry move command. If the problem recurs, issue an Initialize Element Status command followed by a Read Element Status command and retry Move command. 5 5 3B 53 80 03 Illegal request, unable to carry out the requested operation due to a cartridge being in the Hand.
