6.5.3 How to Verify Connectivity Between Nodes
There are two ways to verify the connectivity between nodes: by running get_ci_status(1M) or by running ping(1).
Run the get_ci_status(1M) command on all cluster nodes.
Example output for get_ci_status(1M) is shown below.
# /opt/SUNWsma/bin/get_ci_status sma: sci #0: sbus_slot# 1; adapter_id 8 (0x08); ip_address 1; switch_id# 0; port_id# 0; Adapter Status - UP; Link Status - UP sma: sci #1: sbus_slot# 2; adapter_id 12 (0x0c); ip_address 17; switch_id# 1; port_id# 0; Adapter Status - UP; Link Status - UP sma: Switch_id# 0 sma: port_id# 1: host_name = interconn2; adapter_id = 72; active | operational sma: port_id# 2: host_name = interconn3; adapter_id = 136; active | operational sma: port_id# 3: host_name = interconn4; adapter_id = 200; active | operational sma: Switch_id# 1 sma: port_id# 1: host_name = interconn2; adapter_id = 76; active | operational sma: port_id# 2: host_name = interconn3; adapter_id = 140; active | operational sma: port_id# 3: host_name = interconn4; adapter_id = 204; active | operational # |
The first four lines indicate the status of the local node (in this case, interconn1). It is communicating with both switch_id# 0 and switch_id# 1 (Link Status - UP).
sma: sci #0: sbus_slot# 1; adapter_id 8 (0x08); ip_address 1; switch_id# 0; port_id# 0; Adapter Status - UP; Link Status - UP sma: sci #1: sbus_slot# 2; adapter_id 12 (0x0c); ip_address 17; switch_id# 1; port_id# 0; Adapter Status - UP; Link Status - UP |
The rest of the output indicates the global status of the other nodes in the cluster. All the ports on the two switches are communicating with their nodes. If there is a problem with the hardware, inactive is displayed (instead of active). If there is a problem with the software, inoperational is displayed (instead of operational).
sma: Switch_id# 0 sma: port_id# 1: host_name = interconn2; adapter_id = 72; active | operational sma: port_id# 2: host_name = interconn3; adapter_id = 136; active | operational sma: port_id# 3: host_name = interconn4; adapter_id = 200; active | operational sma: Switch_id# 1 sma: port_id# 1: host_name = interconn2; adapter_id = 76; active | operational sma: port_id# 2: host_name = interconn3; adapter_id = 140; active | operational sma: port_id# 3: host_name = interconn4; adapter_id = 204; active | operational # |
Run the ping(1) command on all the IP addresses of remote nodes.
Example output for ping(1) is shown below.
# ping IP-address |
The IP addresses are found in the /etc/sma.ip file. Be sure to run the ping(1) command for each node in the cluster.
The ping(1) command returns an "alive" message indicating that the two ends are communicating without a problem. Otherwise, an error message is displayed.
For example,
# ping 204.152.65.2 204.152.65.2 is alive |
