Adding SCSI Tape Drive
OS: SuSE 9.0 SCSI HBA: ADaptec 39160 SCSI HD: Single 36GB attached to Channel A with SCSI ID 0 Tape Drive: Tandberg SLR4 with SCSI ID 2 (not yet installed) This system was installed with the sole SCSI HD attached to the 39160 Channel A internal 68-pin connector but now I want to move the tape drive from another system to this one. Sccording to the 39160 Installation Guide, which has the following caution: Do not connect SCSI devices to more than two of the three SCSI Channel A connectors at the same time which would seem to imply I could simply connect a 50-pin cable to the 50-pin internal Channel A connector for the tape drive without violating the caution. Is this correct? Will adding the tape drive to an installed system mess anything up? If so, how should I go about this? Thank you, Lucky Leavell

I have had a SCSI DAT drive connected to the 50-pin connector on a 2940-AUW and a hard drive connected to the 68-pin connector and they both worked, so my guess it is OK. On the Adaptec site, you can find an email address for support and they will answer the question with certainty as they did for me when I had problems with a 2944, the internal drive didn't work, but I could get the external RAID box to work, they set me straight that the 2944 only supported HVD and that it may have damaged either the drive (non-HVD) or the 2944, sure enough, the drive got damaged.

You have 3 connectors on the board, 2 internal and 1 external. This means that you are not allowed to use the 3 connectors at the same time. But you can connect several devices on each . Michel

Well, I finally got the tape drive installed but, contrary to the Adaptec 39160 Installation Guide, I could not use both the 68-pin (for only hard drive) and 50-pin connectors (for tape drive) when both were on channel A. The system would hang after displaying the Adaptec message about using <CTRL>A to enter the Adaptec SCSI-Select utility and would not go further or responf to the <CTRL>A either. Either device showed up fine when the other was unplugged from the 39160 bit not when both were attached to channel A connectors. I finally moved the hard drive connector to Channel B and changed the boot sequence to try B first and everything appears to be working OK. (I would think this may also give a performance boost while using the tape drive.) (I also enabled terminator power on the tape drive and reduced the transfer rate to 10Mb/sec; the tape drive IS terminated and the wide cable which only has a hard drive has an active terminator at the end of the cable.) I did find a technical article on the Adaptec support database but that addresses mixing wide and narrow devices on the same cable which is NOT what I was attempting to do. (To mix wide/narrow on the same cables requires using adapters.) Again, I still do not know why it was necessary to segregate the wide hard drive from the narrow tape drive on separate channels but both are working now! Thank you, Lucky
