This section contains updates to the Spectra T950 Assisted Self-Maintenance 
Guide.

Spectra Logic web site for the most current version of these 
instructions.

A QIP handles all of the communication between the host and the attached 
SCSI drives. It also passes robotic control commands from the host to the 
library’s robotics and can queue drive commands to keep drives streaming 
data for optimum drive performance. Most QIP “failures” can be traced to 
a communication failure somewhere in the communication path. The 
following table lists the two most common “symptoms,” with the 
preferred resolution for each.

Refer to the Spectra T950 Assisted Self-Maintenance Guide for additional 
information about identifying a malfunctioning QIP.

The QIP shows “offline” 
in the front panel library 
interface, and the host can 
no longer communicate 
with the QIP or the drives 
attached to it.

Reset the QIP as described in 

. It will most often resume 

functioning, which indicates that it experienced a communications 
problem with the host. If this problem occurs frequently, locating the 
source of the communications problem is the only way to permanently 
resolve the issue. The source of the problem could be bad media, a 
malfunctioning tape drive, a cable or HBA problem, or another program 
or server interrupting communications. Setting up QIP tracing can help 
identify the source of the problem. Do not replace the QIP.
If the QIP does not resume functioning after a reset, then it is possible 
that a chip on the QIP failed or that there is another hardware problem. 
Replace the QIP.
