CAM Status: SCSI Status Error

[B. Cook]

Hello all,

I saw this the other day.. and it happened while we were moving 
computers around while they were powered on..

Is it something to be worried about or did we just possibly bump the drive?

We've been running the box for over a year w/o any such errors before. 
But it is an older drive.

Thanks in advance.
