La commande 'lscluster -i' permet d'afficher les informations de communication d'un cluster PowerHA.

La syntaxe est la suivante :

Usage: lscluster { -i  | -d | -c [ -n clustername ] } | {  -m [ nodename ] | -s | -i <interface name> | -d <disk name>}

lscluster Command

Purpose

       Lists the cluster configuration information.

Syntax

       lscluster { -i | -d | -c [ -n clustername ] } | { -m [ nodename ] | -s | -i interfacename | -d
       diskname }

Description

       The lscluster command displays the attributes associated with the cluster and the cluster
       configuration.

Flags

       Item
            Description
       -c
            Lists the cluster configuration.
       -d
            Lists the cluster storage interfaces.
       -i
            Lists the cluster configuration interfaces on the local node.
       -m
            Lists the cluster node configuration information.
       -n
            Allows the cluster names to be queried for all interfaces, storage, or cluster configurations
            (applicable only with -i, -d, or -c flags).
       -s
            Lists the cluster network statistics on the local node.

Examples
       1    To list the cluster configuration for all nodes, enter:

            lscluster m
       2    To list the cluster configuration for the node node1, enter:

            lscluster -m node1
       3    To list the cluster statistics for the local node, enter:

            lscluster s
       4    To list the interface information for the local node, enter:

            lscluster i
       5    To list the interface information for the cluster, enter:

            lscluster i n mycluster
       6    To list the interface information for the interface en0, enter:

            lscluster -i en0
       7    To list the storage interface information for the cluster, enter:

            lscluster -d
       8    To list the cluster configuration, enter:

            lscluster -c
