3.3.8 Controlling Mailslot Rotation
Configurations 31 and 32 allow control of mailslot rotation as described below.
(See Section 3.3.1)
Note
In its default state, the optical disk library’s mailslot stays open, ready to
accept an optical disk.
The following configurations allow control over the mailslot’s position.
• CONF 31 - when this is set to ON and CONF 15 is also set to ON, the mailslot’s
default position is closed. The mailslot cannot be opened and disks cannot
be inserted or removed until
CONF 15
, (requires a security code to set), is set
to
OFF
. Setting this configuration to
ON
makes it visible to the user that the
mailslot cannot be used until security configuration 15 is switched OFF.
If the autochanger is full, the mailslot will only open for an eject command.
•
CONF 32
- when this is set to ON, the mailslot can be rotated open or closed
from the control panel or it allows the host to control mailslot rotation using
a SCSI Rotate Mailslot command. Pressing
NEXT
on the disk library’s control
panel displays an
OPEN MS
or
CLOSE MS
message. When the open or close
message displays, press
ENTER
to toggle the mailslot open or closed.
If the autochanger is full, the OPEN/CLOSE MS is not displayed and the mailslot
will only open for an eject command.
3.3.9 Host Configuration
Once the disk library is connected to the host system and the device address is
set, you are ready to prepare the host system to access the library. To determine
if the host you are connecting to supports the optical disk library and for further
installation information, check the following documents:
• Product support plan (available from your local Sales Support Office)
• Host system documentation.
