Daisy Chain Quantum LTO-6 HH Tape Drives

I have 2 Quantum LTO-6 HH Tape Drives.  I would like to daisy chain them together because I only have 1 available SAS port on my server.

Both drives have 2 SAS ports on the back.

I plugged one cable from server to Drive 1 SAS Port.  Then plugged 2nd SAS cable from 2nd port on Drive 1 to 1st port on Drive 2.

I cannot see the 2nd drive.

What am I missing?

Model B or Model C?
Documentation http://downloads.quantum.com/lto6hh/Model-C/6-68132-01_Quantum_LTO-6_HH_SAS_Model_C_User%E2%80%99s_Guide.pdf
for Model C on page 26 says this:
"Connect the SAS Interface Cable
Each tape drive is required to have
 a dedicated bus to the initiator,
referred to as point-to-point conn
ection. SAS architecture does not
support multiple tape drives connect
ed to a single
host adapter port.
The maximum SAS cable length that
can be used to connect the host
adapter to the tape drive is 5.5 m".
So I would say not workable, sounds logical though.  The old SCSI could be set to different IDs and thus daisy chained, but I guess SAS is better???

You can't daisy-chain SAS, The two ports on the drive are in case you want to connect the drive to two servers so if one fails the backup can be restarted on the other.

If you have one external port it probably has 4 lanes and you can use one lane per tape drive with a splitter cable.

For example - http://www.lightinthebox.com/30awg-internal-mini-sas-36pin-sff-8087-male-w-latch-to-sata-7pin-female-x4-forward-breakout-cable-black-1-0m_p691682.html (may not be the correct ends but there are other types that split the 4 lanes like this.
