WHAT YOU SEND TO THE AUTOLOADER
InvACln – Byte 05, Bit 3 (Invisible AutoClean Cell)
This field specifies whether the autoloader makes the cell reserved for
autocleaning, if any, invisible to the host. When this bit is set, the reserved cell
cannot be addressed by any SCSI command. See “FixEnbl – Byte 02, Bit 0” on
page 9-12 for additional information about the AutoClean cell.
0 – Do not hide AutoClean reserved cell
1 – Hide AutoClean reserved cell
The factory default is 0.
This field is kept in nonvolatile RAM, and once set, remains in effect, even
between power-on cycles, until changed by this command.
Dead – Byte 05, Bit 2 (Dead Device)
This field indicates that the autoloader requires service, as follows:
0 – The autoloader does not require service.
1 – The autoloader requires service.
The factory default is 0.
This bit is normally set during operation if a non-recoverable mechanism error
is detected. The field is usually cleared after the problem has been resolved.
The field can be set to 1 for diagnostic purposes.
This field is kept in nonvolatile RAM, and once set, remains in effect, even
between power-on cycles, until changed by this command.
RespDuringBusy – Byte 05, Bits 1 and 0 (Response During Busy)
This field indicates how the autoloader responds to a motion command
received while it is busy completing another motion command (for example,
MOVE MEDIUM, INITIALIZE ELEM STATUS). Ta b l e 9 - 3 lists the valid values
for this field.
This field is kept in nonvolatile RAM, and once set, remains in effect, even
between power-on cycles, until changed by this command.
