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:
