Could someone answer a couple of SCSI cabling question?
I recently had to replace a failed drive on a 2- Quantum 4.3G SCSI drive Windows NT server.
Here is the configuration:
Server
Disk 0 - Quantum 4.3G scsi drive (working fine)
First physical drive on controller card
Disk 1 - Quantum 4.3G scsi drive (failed)
Second physical drive on controller card
The Adaptec 2940UW controller was configured as follows.
Device #0 - Disk 0 (also the boot disk, I THINK it is terminated)
Device #3 - Disk 1 (not terminated)
Device #7 - Adaptec 2940UW controller card (terminated)
Here are the questions:
1 - Device #3 is attached to the third connector on the chain, it's also the last device on the chain, should it be terminated?
2- If I terminate Device #3 then Device #0 will be in the middle of the chain.
Will Device #0 still be shown as Disk 0?
3- The device order on the cable will be #7-Controller (terminated), #0 Disk 0 (not terminated), #3 Disk 1 (terminated).
a. Will this work correctly?
b. Do I need to change the Device number order to be #7, #3, #0?
4- The current setup is
Device #7 - controller (terminated),
Device #0 - Disk 0 (terminated),
Device #3 Disk 1 (not terminated).
Disk 1 is still able to be written to and read from. If a Device has two terminated Device's earlier in the chain, why is it that the Device is even usable?
Any and all help would be appreciated.
Thanks,
Jim Gemeinhardt
