set expander-fault-isolation Description For use by or with direction from a service technician. By default, the Expander Controller in each I/O module performs fault-isolation analysis of SAS expander PHY statistics. When one or more error counters for a specific PHY exceed the built-in thresholds, the PHY is disabled to maintain storage system operation. 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. Syntax set expander-fault-isolation wwn enclosure-wwn controller a|b|both enabled|disabled|on|off Parameters wwn enclosure-wwn The WWPN of the enclosure containing the Expander Controller whose setting you want to change. To determine the WWPN, use show enclosure-status. controller a|b|both The I/O module containing the Expander Controller whose setting you want to change: A, B, or both. enabled|disabled|on|off Whether to enable or disable PHY fault isolation. Example Disable PHY fault isolation for Expander Controller A in an enclosure: # set expander-fault-isolation wwn 500C0FF00A408A3C controller a disabled Success: Disabled expander fault isolation. Re-enable PHY fault isolation for Expander Controller A in the same enclosure: # set expander-fault-isolation wwn 500C0FF00A408A3C controller a enabled Success: Enabled expander fault isolation.
