Get Cluster Interconnection Information

Command

/usr/cluster/bin/scstat -W

Example of output

-- Cluster Transport Paths --

Endpoint Endpoint Status

-------- -------- ------

Transport path: node1:bge3 node2:nxge11 Path online

Transport path: node1:nxge3 node2:nxge3 Path online

Values taken

Output contains the list of transport paths with their statuses.

For each path which is online we get source interface on a source node and target interface on a target node.

Comments

Such transport path will be reported with Layer2 links from source interface to target interface.

To report the remote interface (located on a node which is not the one connected to), the MAC addresses described below are retrieved.

Values taken

Private network address.

List of interfaces that are used in cluster interconnect: name and IP address assigned.

Command

/usr/sbin/arp 172.2.0.10

Example of output

172.2.0.10 (172.2.0.10) at 0:21:a8:39:33:a9

Values taken

MAC

Comments

Discovery resolves the MAC address of remote interface via arp. If it cannot be resolved, Discovery does not report the transport path as Layer2 link.
