This document is intended to provide a basic overview on how to troubleshoot faults with the array RAID controller Host Interface Cards (HIC).

Please validate that each troubleshooting step below is true for your environment. Each step will provide instructions via a link to a document, for validating the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.


HIC faults come in two basic varieties.

A degraded HIC is one where at least one host port is able to transport data.  A failed Host Card is one where no host ports can transport data.  In both of these cases, the array controller will still be in an Online state.

A volume not on its preferred path is a secondary symptom to a HIC fault, and if none of the other alarms are present, should be ignored as part of this document.  This fault will not be addressed beyond this point in the document.
