Troubleshooting

USB CLI port connection

RPC24 694xx 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

RPC24 694xx 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 Basic operation
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 RPC24 694xx Series Storage Management 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 Gather fault information
• Determine where in the system the fault is occurring
(see Determine where the fault is occurring
• Review event logs
(see Review the event logs
• If required, isolate the fault to a data path component or configuration
(see Isolate the fault
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
replication faults

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 the SMC or 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, either the
SMC or RAIDar, and the CLI provide recommended-action text online. Options for performing basic steps are
listed according to frequency of use:
•

Use the SMC or RAIDar

• Use the CLI
• Monitor event notification
• View the enclosure LEDs
Use the SMC or RAIDar
The SMC and RAIDar use health icons to show OK, Degraded, Fault, or Unknown status for the system and its
components. The SMC and RAIDar enable 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 the web application's GUI
on page 50, use the SMC or RAIDar to configure and provision the system upon
