Troubleshooting
USB CLI port connection
AssuredSAN Ultra48 Series 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 Appendix D for more information.
Fault isolation methodology
AssuredSAN Ultra48 Series 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 (Field
Replaceable Units) affected.
As noted in
on page 51, use RAIDar to 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” within the
AssuredSAN Series 4004 RAIDar User
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:
•
Gather fault information, including using system LEDs
(see
•
Determine where in the system the fault is occurring
(see
Determine where the fault is occurring
•
Review event logs
(see
•
If required, isolate the fault to a data path component or configuration
(see
Cabling systems to enable use of the licensed AssuredRemote feature—to replicate volumes—is another
important fault isolation consideration pertaining to initial system installation. See
for more information about troubleshooting during initial setup.
Options available for performing basic steps
When performing fault isolation and troubleshooting steps, select the option or options that best suit your
site environment. Use of any option (four options are described below) is not mutually-exclusive to the use
of another option. You can use RAIDar to check the health icons/values for the system and its components
to ensure that everything is okay, or to drill down to a problem component. If you discover a problem, both
RAIDar and the CLI provide recommended-action text online. Options for performing basic steps are listed
according to frequency of use:
•
Use RAIDar
•
Use the CLI
•
Monitor event notification
•
View the enclosure LEDs
Use RAIDar
RAIDar uses health icons to show OK, Degraded, Fault, or Unknown status for the system and its
components. RAIDar enables you to monitor the health of the system and its components. If any component
has a problem, the system health will be Degraded, Fault, or Unknown. Use RAIDar’s GUI to drill down to
