CLI Guide

While troubleshooting a storage system problem, a service technician can use this command to temporarily
disable fault isolation for a specific Expander Controller in a specific enclosure.
NOTE: If fault isolation is disabled, be sure to re-enable it before placing the system back into
service. Serious problems can result if fault isolation is disabled and a PHY failure occurs.
