[rescue] Problem with scsi disks

[Paul]

I would check the obvious:
SCSI cable good? Not pinched, overly bent, and is well connected?

Termination? Only one drive terminated, or, possibly (depending on the
machine you have it in), none terminated?

Connections? Everything plugged in securely?

In general, most SCA drives seem to be designed to work best with all
jumpers removed. This is a rule of thumb, your drives/system may vary from
this.

Could you offer more information? What type of drives? (SCA, wide, ultra?)
What system is it on and are the drives internal or external? Do you have
external drives?

It really sounds like a cable or termination error, if the simple stuff here
doesn't work we can go farther in troubleshooting.

Good luck
Paul
