Status indicators

If a SAS port or cable is not functioning correctly, the system writes an entry to the system Error Log. To find the entry in the management GUI, select Monitoring > Events.

You can also use the management GUI to display status information about the SAS ports. To do so, select Monitoring > System - Overview; then, select the control enclosure that contains the SAS ports. Select System - Enclosure Details for the control enclosure. Then, select SAS Ports to see the status of the SAS ports.

You can also use the lsportsas command to display the status and configuration of the SAS ports within the entire system. Use the node_id, node_name, port_id, and status fields of the command output to locate information about the node and SAS ports of interest.
