lsnodeipconnectivity
Use the sainfo lsnodeipconnectivity command to list the port level iSER (iSCSI Extensions for RDMA) clustering session connectivity information.
Syntax
Parameters
- (Optional) Specifies the system or node on which the command is invoked. The value must be an alphanumeric string.
Description
This command lists the port level connectivity information for node to node or clustering connectivity.
This table provides the attribute values that can be displayed as output view data.
The following table lists the values for the error_data field and
possible corrective actions.
Attribute | Description |
---|---|
status | Indicates the status of the connection attempt for the port level
connectivity for node to node or clustering. A value of Discovered
indicates that ports are configured, but the connection could not be established. The
reason for the connection issue is described in the error_data field.
A value of Connected:protocol indicates a successful connection. |
local_port_id | Indicates the local port identifier for the node Ethernet port number that is displayed in the lsservicestatus output. |
local_vlan | Indicates the local port Virtual LAN Identifier for the node Ethernet port number that is displayed in the lsservicestatus output. |
local_rdma_type | Indicates the local port RDMA type. |
local_ip_addr | Indicates the local IP address. |
remote_port_id | Indicates the peer or target port identifier for the node Ethernet port number that is displayed in the lsservicestatus output. |
remote_vlan | Indicates the remote port Virtual LAN Identifier for the node Ethernet port number that is displayed in the lsservicestatus output. |
remote_rdma_type | Indicates the remote port RDMA type. |
remote_ip_addr | Indicates the remote IP address. |
remote_wwnn | Indicates the remote World Wide Node Name (WWNN). |
remote_panel_name | Indicates the remote node unique panel name. |
cluster_id | Indicates the Cluster ID of the peer system. |
error_data | Displays information that details any problems with the connection. |
error_data value | Description | Possible Corrective Action |
---|---|---|
Protocol mismatch | Source port RDMA adapter and destination Port RDMA adapter are not compatible with each other. | Make sure that both of the RDMA adapters are the same type (Ex: RoCE to RoCE, iWARP to iWARP). |
Unreachable | The source IP address and destination IP address are not reachable. | Make sure that both of the IPs are reachable. You can use the satask
ping command to check the network connectivity of the local and remote
ports. |
Duplicate IP | A duplicate IP address is set. | Make sure that the IP addresses that are set are unique on the same network. |
Degraded | Negotiated speed does not match. Degraded is set when a slower speed is selected than the adapter supported maximum speed. | Make sure that the switch adapters on both nodes support the maximum speed. |
VLAN ID Mismatch | The local and remote port Virtual LAN Identifiers do not match. | For the clustering link to get created, make sure that the VLAN IDs match. |
