Selection of Cleaning Mode
Selection of Cleaning Mode
The cleaning mode is selectable by using either the diagnostic software, the
control panel, or a host initiated Mode Select command. A host initiated
Mode Select command is the only way to permanently change the cleaning
mode in the library’s NVRAM. The default cleaning mode is Host Initiated
Cleaning Mode, which disables all library support for drive cleaning. The
cleaning mode, if saved in the library’s NVRAM, is retained when the library
power is cycled.
Diagnostic Software
To enable Fully Automatic Cleaning Mode, select “Enable Clean Tape” from
the “Config” Menu of the Diagnostic Software.
Control Panel
To enable Fully Automatic Cleaning Mode, select “Enable” from the
“AutoClean” submenu of the “Configuration” menu from the control panel.
Note
When the cleaning mode is selected using the diagnostic software or control
panel, it is retained only until the library power is cycled. The diagnostic
software and the control panel cannot permanently change the cleaning
mode in the library’s NVRAM.
Mode Select Command (Host Initiated)
The cleaning mode may be set in the Vendor Unique Page 00h (which can be
permanently saved to the library NVRAM) by the host using the Save Page
bit. A host initiated Mode Select command is the only method that can
permanently change the cleaning mode in the library’s NVRAM.
Note
A SCSI bus reset will not change the cleaning mode.
To enable Fully Automatic Cleaning Mode, the host must set bit number 1 in
the first parameter byte (following the Page Length byte in the vendor unique
page).
To enable Host Initiated Cleaning Mode, the host must clear bit number 1 in
the first parameter byte (following the Page Length byte in the vendor unique
page). The cleaning mode can be permanently saved to the library’s NVRAM
by using the Save Page bit.
