14.3 Verify the Switch Status

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).
