- Power Cycle-The Power Cycle option initiates a warm reboot of the IOM. In this instance, the power is not removed from the IOM and the core systems of the IOM reboot. - System Reseat-The System Reseat option initiates a cold reboot of the IOM. In this instance, the power is removed from the IOM and the IOM reboots. • Blink LED-Turn on or turn off to identify the IOM LEDs. • Clear Configuration-Delete the storage IOM configuration. • Extract Log-Extract the IOM activities log to a CIFS or NFS share location. • View a list of the latest alerts and the date and time when the alerts were generated, in the Recent Alerts section. To view a list of all alerts click View All. The Alerts page with all alerts that are related to the IOM is displayed. • View a list of all activities that are related to the IOM, the rate of completion of the activity, and the date of time when the activity began, in the Recent Activity section. To view a list of all activities that are related to the IOM, click View All. The Jobs page with a list of all the jobs that are related to the IOM is displayed. • View the power statistics of the IOM by clicking View Power Statistics in the Environment section. The statistics comprise peak power time stamp, minimum power time stamp, date, and time from when the statistics is recorded. Click Reset to reset the power statistics data. NOTE: If you perform the Clear operation on a SAS IOM, the IOM becomes active, if it is not already active and, the storage configuration on both the SAS IOMs is cleared. NOTE: Resolve any suboptimal health of the IOM, other than firmware mismatch, before updating the firmware. This action ensures that the firmware is updated without downgrading the health of the SAS IOM. Force active You can use More Actions > Force Active to perform a failover on a "Passive" or "Degraded" switch. Performing a "Force Active" operation on the SAS IOM is considered a disruptive operation and must only be used if necessary. When you perform a "Force Active" operation, the SAS IOM becomes "Active" and the associated storage configuration is applied to the chassis. You can use the Force Active option to resolve mismatches that occur when: • The switches were configured earlier but are inserted in a chassis that did not have SAS IOMs earlier. • Two switches from two different chassis are inserted into a third chassis. You can also use Force Active as a preemptive action for servicing a switch. Ensure that the remaining switch is "Active" before removing the switch that must be serviced. This in turn, prevents any disruption to the fabric that might occur if the switch is removed when the other switch is "Passive". Clearing configuration You can clear the storage configuration of the SAS IOMs using More Actions > Clear. When you click Clear, the SAS IOM becomes "Active" and the storage configuration is cleared from the chassis. You can use the Clear option to: • Reset a chassis configuration in one step. • Resolve a worst case mismatch where two switches are taken from two different chassis and inserted into a third chassis. In this scenario, it is unlikely that the two switches have a correct configuration. It is recommended that the Clear option is used to clear existing configuration and create a correct configuration. Use the Force Active and Clear options to act upon some critical and warning messages that are displayed in the OME-Modular web interface, particularly, for a configuration mismatch. 48 Managing Storage
