The CDR100 offers a capacity of 100 CDs and a high performance due to its small
size.
The devices are controlled efficiently by serial lines using a special protocol
which allows up to 16 devices to be daisy-chained. The robot ID robid
is a number between 0 and 15, so that up to 16 devices can be controlled by a
single serial line.
Starting with version 2.1, you can combine the settings for the robot and the
robot ID using the syntax robot=<serial
port>,<robid> which can be used instead of two
separate lines robot and robid. For example,
robot=com1:,4 or robot=/dev/ttya,4
With the CDR100, use the same number for SCSI-ID and robot ID, especially if
you have more than one (up to seven) devices. Refer to the CDR100 manual for
information about changing the robot ID.
The CDR100 has a single drive and no mail slot, so you cannot instruct the
server to export a disk to a mail slot. You change CDs by detaching the
jukebox, changing the CDs manually, closing the jukebox, attaching the jukebox
to the server, and calling:
cdadm testcd <device> <list>
which instructs the server to inspect the slots enumerated in
<list>.
If you cannot detach the jukebox because you want to change CDs while the file
system is in use and you do not want to cause errors, use cdadm insert
and cdadm remove, to block user requests.
The cdadm insert <device> and cdadm remove
<device> commands instruct the server to free the drive in
the jukebox, so you can open the door and change disks without impacting the
clients. Clients do not receive errors, but they must wait for a response. As
soon as you finish changing the CDs, close the door and tell the server which
CDs you changed and to resume to normal operation. For example after you
blocked the jukebox using the command
cdadm insert <device>
and changed the CDs in slots 2, 3, 4, 5, and 8, call the command
cdadm testcd <device> 2-5,8
which instructs the server to inspect slots 2-5 and 8 and to resume normal
operation, including execution of all requests for the jukebox that were
blocked while you changed CDs. Be sure to change the CDs quickly so users do
not have to wait for responses longer than necessary.
The CDR100 can be fitted with recorders supported by iXOS-JUKEMAN.
