Sequential Access Device log page
The Sequential Access Device Log page is page 0Ch. The Page Length is 40h. Five parameters are supported, all eight bytes long. With the exception of 0100h (cleaning required), they are updated when a data set is logically written and cleared at the start of tape load; the values of each parameter relate to the current tape.
Parm. Description
0001h The number of data bytes received from application clients during write command operations. This is the number of bytes transferred over SCSI, before compression.
0002h The number of data bytes written to the media as a result of write command operations, not counting the overhead from ECC and formatting. This is the number of data bytes transferred to media, after compression.
0003h The number of data bytes read from the media during read command operations, not counting the overhead from ECC and formatting. This is the number of data bytes transferred from media with compression.
0004h The number of data bytes transferred to the initiator or initiators during read command operations. This is the number of bytes transferred over SCSI, after decompression.
