scsi controler config error: 02

[David Whittingham]

Hi,

Im getting the above error message connecting an HP Surestore 1200ex to Adaptec 29160 cards.

all I've read so far indicates a likely problem with the cards only working with LVD/SE devices.

Can anyone confirm if the surestore 1200ex is an HVD or LVD device?

Thanks in advance

David

This jukebox is a â fast and narrowâ SCSI device with the capability to connect to
either a narrow single-ended bus or a wide differentia

Hi David, where the cable connects to on your juke-box is a tiny slide switch which will allow you to change your machine from single ended to differential. Not certain what variety your adaptec board is but it is changeable. There should be 2 terminators attached, one for single ended and the other for differential

hope this is of use
cheers

Previously we had been connecting to this device using the HD50 interfaces so I had used the micro switches to move to the HD68 interfaces.

The informnation on the addaptec site indicates that the cards I have will only support Low Voltage Differential (LVD)devices and the error I'm seeing suggest the device is High Voltage Differential. Is this the case or do I have another configuration error somewhere?

Thanks

David

This is what Adaptec say....

Basically, the card detected a configuration error, most likely on the SCSI bus. It is possible that the termination on the SCSI bus or the cable itself might have gotten defective. For test, please try to disconnect all SCSI devices on the card. Boot the system and see if you still get the error.

Most of the times, this error message will appear when connecting an HVD (High Voltage Differential) SCSI device to the Low Voltage Differential (LVD) SCSI card. Ultra160 SCSI cards only support the use of Low Voltage Differential (LVD) and Single-Ended (SE) devices.

CAUTION! Connecting HVD devices to a non-HVD SCSI controller may damage both the device and the SCSI controller.

Determine if your device(s) being attached is a HVD device. Check for any markings on the device, typically near the SCSI connector that may indicate HVD or LVD/SE. However do not trust these marking completely, double check the type of device inside the unit. Although the external case may be marked as LVD, it is still possible the internal device may still be an HVD device.

The manufacuter of the device(s) should be contacted, if reviewing the documentation or visiting the manufacturers web shed light on the interface style the device is using.

Note: When using a HVD (High Voltage Differential) device, a HVD SCSI card must be used.

Hi David, in your second response you say that your controller will support LVD/SE so I should continue to use your 50 pin connector and get a converter that will take down your 68 pin connector to a 50 pin. These are readily available, or even get the cable( part number 5181-7707)
hope this helps

Malvin,

Thanks for this. I'll try to source some cables prior to re-testing. I had difficulty finding VHDCI to HD50 cables hence going for the VHDCI to HD68. I hadn't appreciated there was a difference between the busses.

Regards

David

The 68pin connector on those libraries is HVD only. To operate in SE mode you must connect to the 50 pin connector. If you want to use the 68 pin then you need an Adaptec 2944 HVD card.
