How to configure EML103e using SLES9?

We have an EML103e fibre attached (via SAN) to a SLES9 box.

In the /proc/scsi/qla2xxx/0 and 1 I can see the HBA's of the EML.

How can I get the library to be recognised by the OS?

Most tape devices should show up in /dev after rebooting...

Thanks but been there, done all that.

I can see the /dev/st0 and /dev/st1 drives. However I cannot seem to find a device for the EML library.

Any ideas?

You need to configure the embedded E2400 "storage router" (=FC bridge) to map the EML's devices into the FC LUN address space of the Linux server.

Ah, responses crossed ;-)

Do you see any "sg" devices?

Yup:

# lssg
sg0 0,0,0,0 HP HSV200 5030 5000-1fe1-5007-6ff9
sg1 0,0,0,2 HP HSV200 5030 5000-1fe1-5007-6ff9
sg2 0,0,0,8 HP HSV200 5030 5000-1fe1-5007-6ff9
sg3 1,0,1,0 HP EML E-Series 1022 1000-00e0-0223-39e4
sg4 1,0,1,1 HP Ultrium 3-SCSI L29S 1000-00e0-0223-39e4
sg5 1,0,1,2 HP Ultrium 3-SCSI L29S 1000-00e0-0223-39e4


0 is a scsi raid device and 1 and 2 are FC luns.

What are you thinking?

Looks like "sg3" is the robotic, "sg4" and "sg5" are the tape drives.

Um yes, but usually (and here I'm thinking IBM3494 robots) there is a piece of software that drives the ATL and communicates with it at a much higher level.

I guess that I must be missing something I have yet to find out about.

Oh well. Back to the old drawing board.

Found out what it was shortly after (but did not know how to find this old thread:

The EML library's firmware by default does not read barcodes properly. All barcode labels from HP are 8 characters long yet the robot's set up for 6.

Believe it or not, that was it.
