USB CLI Port Connection
Quantum QXS Storage controllers feature a CLI port employing a mini-USB Type B form factor. If you
encounter problems communicating with the port after cabling your computer to the USB device, you may
need to either download a device driver (Windows), or set appropriate parameters via an operating system
command (Linux). See
for more information.
Fault Isolation Methodology
Quantum QXS Storage storage systems provide many ways to isolate faults. This section presents the basic
methodology used to locate faults within a storage system, and to identify the pertinent FRUs affected.
As noted in Basic Operation Overview
, configure and provision the system upon completing the
hardware installation. As part of this process, configure and enable event notification so the system will
notify you when a problem occurs that is at or above the configured severity (see “Using the Configuration
Wizard > Configuring event notification” in the QXS Storage Disk Storage Management Utility Users
Guide). With event notification configured and enabled, you can follow the recommended actions in the
notification message to resolve the problem, as further discussed in the options presented below.
Basic Steps
The basic fault isolation steps are listed below:
l
Gather fault information, including using system LEDs. See Gather Fault Information
l
Determine where in the system the fault is occurring. See Determine Where the Fault is Occurring
.
l
Review event logs. See Review the Event Logs
.
l
If required, isolate the fault to a data path component or configuration. See Isolate the Fault
.
