CHAPTER 10—MODE SENSE (1Ah)
Parameter Length – Byte 01
This field indicates the length, in bytes, of the Cleaning Configuration page.
The valid value for this field is 02h (2), which indicates that 2 bytes of data
follow this byte.
Auto – Byte 02, Bit 1
This bit indicates whether the library will use the cleaning cartridge in the
fixed cleaning cartridge cell to clean the tape drive automatically when
required, as follows:
This bit is only valid when the FixEnbl bit is 1.
FixEnbl – Byte 02, Bit 0
This bit indicates whether the library has a fixed cell reserved for a cleaning
cartridge, as follows:
When the FixEnbl is set to 1, the storage element with the highest element
address is reserved for a cleaning cartridge. That storage element is then
unavailable for storing a data cartridge. Refer to the Magnum 224,
StorageLibrary T24, or StorageLoader 2U LTO Library Product Manual or the
Magnum 448 LTO Library Product Manual more information about the library’s
Autoclean option.
Notes:
When both the FixEnbl and the Auto bits on the Cleaning Configuration Page are
set to 1 (that is, when a cell is reserved for a cleaning cartridge and the library is
configured to automatically handle cleaning), the cell reserved for the cleaning
cartridge, with the highest element address, is removed from the cell geometry.
The status of reserved cell is not reported in response to the READ ELEMENT
STATUS or READ ELEMENT STATUS WITH RANGE commands.
The reserved element address is invalid for motion commands (for example,
MOVE MEDIUM, POSITION TO ELEMENT).
The valid value for the Number of Storage Elements field on the Element Address
Assignment Page (1Dh) for MODE SELECT and MODE SENSE is one less than
when there is no Fixed Autoclean cell.
0 Do not automatically clean drive
1
Automatically clean drive when required if a cleaning
cartridge is available
0 No cleaning cartridge reservation
1
Highest numbered Storage Element reserved for cleaning
cartridge
