CHAPTER 8—LOG SENSE (4Dh)
Total Puts – Bytes 04 through 07
The Total Puts field indicates the total number of puts to the element location
indicated by the element address. The total number of puts is stored in volatile
memory. This value cannot be cleared by a LOG SELECT command with the
Parameter Code Reset bit set.
Total Put Retries – Bytes 08 and 09
The Total Put Retries field indicates the total number of times the library had to
retry a put operation to the element indicated by the element address. The
total number of put retries is stored in nonvolatile memory. This value cannot
be cleared by a LOG SELECT command with the Parameter Code Reset bit set.
Total Pick Retries – Bytes 10 and 11
The Total Pick Retries field indicates the number of times the library had to
retry a pick operation from the element indicated by the element address. The
total number of pick retries is stored in nonvolatile memory. This value cannot
be cleared by a LOG SELECT command with the Parameter Code Reset bit set.
8.3.6 CARTRIDGE SCAN RETRIES PAGE (PAGE CODE 34h)
The Cartridge Scan Retries page returns the total number of times the library
had to retry scanning the cartridge located in the element. This value is stored
in volatile memory for each cartridge and is reset whenever the library is reset,
powered-on, or the door is opened. This value can also be cleared by a LOG
SELECT command with the Parameter Code Reset bit set.
The value that you specify for the Parameter Pointer field of the CDB (bytes 05
and 06) determines the value that the library returns in the Parameter Code
field of the Cartridge Scan Retries page. This value specifies the first element
(starting Element Address) for which information is returned.
A Cartridge Scan Retries page is returned for all subsequent elements (in
ascending element address order) until the allocation length specified in the
CDB has been reached or all element information has been sent. Element
addresses can be changed with the MODE SELECT command.
