SCSI Questions

[techie99]

I am a newbie at SCSI. The network admin asked me to install an external tape device to the server. In the registry I examined the HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SCSI key and it had the following subkeys:
Scsi Port 0
Scsi Port 1
Scsi Port 2

If I go into Start-Settings-Control Panel-Scsi Adapters I can glean the following information:
SONY TSL-11000 is SCSI Port 0 (external tape drive)
NEC CD-ROM DRIVE is SCSI Port 1
SONY TSL-9000 is SCSI Port 1 (internal tape drive)

Since ports 0, 1 and 2 were presumably used by these other devices, I set the external tape SCSI ID to 3 and daisy chained it to the other external tape device after shutting down the server and cutting power to it and the tape device. I then turned on the external tape devices then turned on the server. When I went into SCSI adapters in start-settings-control panel--I had "no device found" where the SONY TSL-11000 (external) had been earlier.

I was hoping somebody could show me the error of my ways and point me in the right direction...

Thanks.

DOes your SCSI card not show you a list of devices and IDs while the computer is booting. It sounds like you have two SCSI channels, 0 & 1. This is different from SCSI IDs. ALthough just as a guess I would try changing the SCSI ID of the New external tape drive and try again. Also, check the termination fo the external devices. Only the last physical drive on the chain should be terminated. If you put the new drive in front of the old drive and the new drive is terminated, the old tape drive might not show up. But it most likely is the SCSI ID that is the problem.
