Solaris

Guys,
I have googled and checked this forum in detail and couldn't find any satisfactory answers for my problem.
I am trying to connect a external SCSI hard Drive(Sea Gate) to a Ultra 80.
I connected it powered it up and at OK prompt did : boot -r
system comes up and complains about not recognizing c1t1d0s6 (this is my external hard drive). I go to single user mode and try to mount it :
mount /dev/rdsk/c1t1d0s6 /abc --> it complains can't find device ( or something like that).
I stop my machine and at OK prompt type probe-scsi-all. Initially it was giving me "bus fault" (then I thought maybe my cable is bad) got a new cable but the same issue. Then I did reset-all and did probe-scsi-all and it starts seeing drive (but showing unconfigured).
If i type format command it doesn't see the external hard drive.

I am thinking my hard drive is bad , but can somebody think of something else before i spend money and buy a new hard drive.

Thanks

which scsi controller do you use? are both scsi devices the same? for example SE or LVD or ...? do you use termination?

I am not sure about what scsi controller ??
I am using a Sun Ultra 80 and trying to talk to "Ultra Scsi" hard drive.
Is there a command I can use to find out what scsi controller I am using ??

From the ok> prompt, can you probe-scsi-all and able to detect the device?

Please provide output from the following commands:

Code:

cfgadm -avl c1
prtdiag -v
prtconf | grep -v not
ls -l /dev/dsk/c1t1d0

Here is the outputs of the commands:
1 ) cfgadm -avl c1
Output is :

It looks a little bit strange... Perform also the next commant and post results:

Code:

devfsadm -Csv
