SUN DDS-4 & SCSI

[Peter Rodwell]

Hi! I have a Proliant DL380 G4 sever with 3 SCSI Disks, I am trying to connect an external DDS-4 Model 599-2350-01 tape drive to the external VHDCI connector, but I keep getting this message from the 6i Array controller:

1776-Slot-0 SCSI bus error - Single Ended SCSI Enclosure or devide attached. This controller model only supports LVD enclosures.

From the documentation I read it is possible to connect this devices to the port, can somebody please help me with this?

Thank you

looks like you have a bad cable, bad terminator or bent/broken pin, Also it is not suggested to attach a tape drive to a raid controller, this will keep the bus busy slowing down all the server activity, I suggest you to attach to a own hba

The funny thing is that I have a HP integryty rx1600 and the drive works perfectly. :(

I do not know the integrity server, but I got these info on the manual:
----------------------
The HP Integrity rx1600 Server features a two-channel Ultra320 SCSI controller on the main system board. U320 SCSI operates at transfer rates of up to 320 Megabytes per second and is backward compatible with all Single-Ended (SE) and narrow (8-bit) SCSI devices A standard, external 68-pin high-density connector to attach any compliant external SCSI device(s) to the second U320 port of the 1030 controller.
There are SCSI termination devices built into both the system board and the SCSI backplane for channel A. SCSI termination is present on the system board for channel B as well.
The termination circuitry for channel B cannot be disabled, limiting the SCSI topologies supportable by this external port. (Specifically, the external SCSI connector must be located at one end of a SCSI cabling string.) The termination disable circuitry for channel B that is used in the HP Integrity rx2600 Server is not available for the HP Integrity rx1600 Server, because the bus topology is simplified.
-----------------------

I do not understand what is the meaning of"The termination circuitry for channel B cannot be disabled, limiting the SCSI topologies supportable by this external port" I would try to check without terminator on the tape, and also check for any configuration steps in the bios.
What it sound strange to me is that the errors are comming from the array controller driver. I would expect from a standard scsi driver.

and is it a type? you have SUN on integrity server, or a dat configured for SUN environment?

have a look at the following doc if it apply:
