76 Events and event messages
Description/Recommended actions
• No action is required.
The controller has detected an invalid disk dual-port connection. This event indicates that a controller host
port is connected to an expansion port, instead of to a port on a host or a switch.
Recommended actions:
• Disconnect the host port and expansion port from each other and connect them to the proper devices.
Errors detected on the indicated disk channel have caused the controller to mark the channel as degraded.
Recommended actions:
• Determine the source of the errors on the indicated disk channel and replace the faulty hardware.
When the problem is resolved, event 189 is logged.
The Management Controller (MC) has powered up or restarted.
Recommended actions:
• No action is required.
The Management Controller is about to restart.
Recommended actions:
• No action is required.
This event is logged when the IP address used for management of the system has been changed by a user or
by a DHCP server (if DHCP is enabled). This event is also logged during power up or failover recovery, even
when the address has not changed.
Recommended actions:
• No action is required.
The Management Controller (MC) has not communicated with the Storage Controller (SC) for 15 minutes
and may have failed.
This event is initially logged as Informational severity. If the problem persists, this event is logged a second
time as Warning severity and the MC is automatically restarted in an attempt to recover from the problem.
Event 156 is then logged.
Recommended actions:
• If this event is logged only one time as Warning severity, no action is required.
• If this event is logged more than one time as Warning severity, do the following:
• Check the version of the controller firmware and update to the latest firmware if needed.
• If the latest firmware is already installed, the controller module that logged this event probably has a
hardware fault. Replace the module.
• If you are not able to access the management interfaces of the controller that logged this event, do the
following:
• Shut down that controller and reseat the module.
• If you are then able to access the management interfaces, check the version of the controller
firmware and update to the latest firmware if needed.
• If the problem recurs, replace the module.
The Management Controller (MC) has not communicated with the Storage Controller (SC) for 160 seconds.
If communication is restored in less than 15 minutes, event 153 is logged. If the problem persists, this event is
logged a second time as Warning severity.
NOTE: It is normal for this event to be logged as Informational severity during firmware
update.
Recommended actions:
• Check the version of the controller firmware and update to the latest firmware if needed.
• If the latest firmware is already installed, no action is required.
