During troubleshooting of an IBM PowerHA SystemMirror cluster, which log file should be checked to identify network communication issues between cluster nodes?
/var/hacmp/logs/cluster.log
ar/hacmp/logs/cluster_nif.log ar/hacmp/logs/cluster_topo.log
wer: C
anation: The /var/hacmp/logs/cluster_nif.log file should be checked d bleshooting of an IBM PowerHA SystemMirror cluster to identify net munication issues between cluster nodes. This log contains informatio
network interfaces and their status.
