For the Sun Datacenter InfiniBand Switch 36, you can check the status of the command-line interface (CLI), power supplies, fans, and switch chip. Verify that the voltage and temperature values of the switch are within specification:
# showunhealthy # env_test
An unfavorable output from these commands indicates a hardware fault with that particular component. A voltage or temperature deviating more than 10% from the provided specification means a problem with the respective component.
For example, on the CLI of the switch, enter the following command to check its status:
# env_test
This command performs a set of checks and displays the overall status of switch, as in the following example:
Environment test started: Starting Voltage test: Voltage ECB OK Measured 3.3V Main = 3.28 V Measured 3.3V Standby = 3.37 V Measured 12V = 12.06 V Measured 5V = 5.03 V Measured VBAT = 3.25 V Measured 1.0V = 1.01 V Measured I4 1.2V = 1.22 V Measured 2.5V = 2.52 V Measured V1P2 DIG = 1.17 V Measured V1P2 AND = 1.16 V Measured 1.2V BridgeX = 1.21 V Measured 1.8V = 1.80 V Measured 1.2V Standby = 1.20 V Voltage test returned OK Starting PSU test: PSU 0 present PSU 1 present PSU test returned OK Starting Temperature test: Back temperature 23.00 Front temperature 32.62 SP temperature 26.12 Switch temperature 45, maxtemperature 45 Bridge-0 temperature 41, maxtemperature 42 Bridge-1 temperature 43, maxtemperature 44 Temperature test returned OK Starting FAN test: Fan 0 not present Fan 1 running at rpm 11212 Fan 2 running at rpm 11313 Fan 3 running at rpm 11521 Fan 4 not present FAN test returned OK Starting Connector test: Connector test returned OK Starting onboard ibdevice test: Switch OK Bridge-0 OK Bridge-1 OK All Internal ibdevices OK Onboard ibdevice test returned OK Environment test PASSED
When the switch status is operational, you can start the Subnet Manager (SM).
