Reviewing the Event Log for Disabled PHYs
If the fault isolation firmware disables a PHY, the event log shows a message like
the following:.
Phy disabled. Enclosure:A00. Phy11. PhysId11 Type:Drive.
Reason:Externally Disabled.
When a PHY has been disabled manually, the event log shows a similar message
with a different reason:
Phy disabled. Enclosure:A00. Phy11. PhysId11. Type:Drive.
Reason:Ctrl Page Disabled.
Resolving PHY Faults
1. Ensure that the cables are securely connected. If they are not, tighten the connectors.
2. Reset the affected controller or power-cycle the enclosure.
3. If the problem persists, replace the affected FRU or enclosure.
4. Periodically examine the Expander Status page to see if the fault isolation firmware
disables the same PHY again. If it does:
a. Replace the appropriate cable.
b. Reset the affected controller or power-cycle the enclosure.
