DETAILS:
1. Stop all Clients /etc/init.d/ibrix_client stop and disable HA ibrix_host -m -U
2. Change the IP on FM and SSs using vi or your favorite editor.
Do this on Fusion Manager and Segment Servers. vi /etc/sysconfig/network-scripts/ifcfg-eth0
Example: DEVICE=eth0 BOOTPROTO=none
HWADDR=00:13:72:3F:3C:DC IPADDR=192.168.14.81 <-- Change the IP here to the new IP.
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
BROADCAST=192.168.14.255
3. Change IPs in /etc/hosts
Example: 127.0.0.1 localhost.localdomain localhost 192.168.14.80 lab14-60.ibrix.com lab14-60 192.168.14.81 lab14-61.ibrix.com
lab14-61 s1 192.168.14.82 lab14-62.ibrix.com lab14-62 s2 Change the FM and SS IPs to the new IPs.
4. Reboot Fusion Manager and Segment servers.
Note: Make sure you can ping segment servers from the fusion manager and fusion manager from the segment servers.
5. Register the segment servers: ./register_host -p < IP of the fusion manger > -c eth0 -h < new IP of the segment server > -s -x
Note: Do this on all the segment servers and make sure you use the x switch.
6. Go to the Fusion Manager and execute the following for each of the segment servers: ./ibrix_nic -c -n eth0 -h -I < IP of the various
segment servers > Make sure that the IPs correspond to the names using the following command: ./ibrix_nic -l
You should see the following output with the new IPs HOST IFNAME TYPE STATE IP_ADDRESS MAC_ADDR lab14-61 eth0
Cluster Active 192.168.14.81 00:13:72:3F:3C:DC lab14-62 eth0 Cluster Active 192.168.14.82 00:13:72:3F:39:AC
