Note:  For production environments, configure more backup repository disks. PowerHA V7.2 supports up to six backup repository disks. It also supports automatic  repository disk replacement in the event of repository disk failure. For more information,  see  IBM PowerHA SystemMirror V7.2 for IBM AIX Updates , SG24-8278. Example 9-14 and Example 9-15 show the output from the PHA170 and PHA171 nodes by  using the  lscluster -m  command. The current heartbeat channel is the network.
