A single width compute sled can support one Fab-C mezzanine card that connects to each IOM through a x4 link. Each lane in the link supports 12Gbps SAS for a total of 48Gbps link to each SAS IOM. In SAS IOMs, the Fab-C IOMs are used to provide SAS switching between compute sleds and internal storage sleds such as PowerEdge MX5016s. For information on the tasks that you can perform on the I/O Modules page for SAS, see Managing IOMs. SAS IOM Overview The SAS IOM Overview page displays details of the IOM, chassis, the list of recent alerts, and recent activities. The IOM information consists of the model, power state, firmware version, fabric type, and management role of the IOM. The management roles can be of three types: • Active • Passive • Degraded A healthy system has one "Active" and one "Passive" SAS IOM. The chassis information consists of the name of the chassis, slot name, and slot number. Information about the SAS IOM storage subsystems is also displayed on the right side of the Overview page. The storage subsystem information consists of the name of the subsystem and health status. Click View Details to view the alerts and alert details. The details consist of the message ID, message, timestamp when the alert was triggered, and recommended action. To view the IOM overview: 1. From the menu bar, click Devices > I/O Modules. The I/O Modules list page is displayed. 2. Select the IOM whose details you want to view. A summary of the selected IOM is displayed on the right side. The summary consists of the name of the IOM, device type, management IP, model, health status, and availability. 3. Click View Details. The Overview page is displayed. On the IOM Overview page, you can perform the following tasks: • Power Control-Turn on, turn off, power cycle, or system reseat operations. • Turn on or turn off-When you turn off the IOM, the status of the IOM is "Offline". As a result, status of the peer IOM may be "Active". When you power cycle the IOM, it causes a warm reboot of the IOM. • 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. NOTE: After the power reseat of the SAS IOM, the IOM turns on within a minute. Any mismatch in the power status of the IOM is corrected through refreshing the inventory or is corrected automatically with the default inventory task. • 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 timestamp, minimum power timestamp, 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. Managing storage 57
