lsnodeipconnectivity

Edit online

Use the sainfo lsnodeipconnectivity command to list the port level iSER (iSCSI Extensions for RDMA) clustering session connectivity information.

Syntax

Parameters

panel_name: (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.

Table 1. sainfo lsnodeipconnectivity output
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.

The following table lists the values for the error_data field and possible corrective actions.

Table 2. sainfo lsnodeipconnectivity error_data
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.
