Table 24 Supported Log Page (00h) Bit Byte 7 6 5 4 3 2 1 0 0 Reserved Page Code (000000b) 1 Reserved 2 Page Length (0002h) 3 4 Supported Log Page (00h) 5 Tape Alert Log Page (2Eh) Page Code - The returned value is 00h, indicating this page. Page Length - The returned value is 0002h. The page codes for all the supported pages (including this one) follow the page length field. Tape Alert Log Page (2Eh) The Tape Alert log page follows the standard log page format. Each Tape Alert is returned as an individual log parameter, with its state reflected in bit zero of the one-byte Parameter Value field of the log parameter. When this bit is set to one, the alert is active. When requesting the Tape Alert log page, the Parameter Pointer determines from what point in the Tape Alert table the alerts are returned. The value zero specifies that all tape alerts should be returned. If the Parameter Pointer is set from 1 to 64, all tape alerts from that point to the end of the list are returned. The various log parameters are listed in the following table.
