Planning the move of the ds8800 hmc IP's to different subnet/IP (behind firewall)
Environment = powerha and system mirror to DR site using 2 ds8800 ESS/DS
HQ and DR ds8800 hmc's will be on the same subnet, but "continue" to be
on a different subnet from the lpars behind the firewalls as they are today.
1) If changing the ds8800 hmc IP addresses, what are the required steps
for changing this information on the AIX PowerHA nodes/lpars System
2) Will this require reboot of all cluster nodes and re-sync? or can this be done online?
