Changing IP Addresses on a XenServer 6.5 Pool

To change the ip addresses on a XenServer 6.5 pool, start with the slaves, and use the following xe commands:

Remember: Slaves first, then the Master

NOTE: There is no need to change the IP from the Management Console.

Find the UUID of the Host Management PIF:

xe pif-list params=uuid,host-name-label,device,management

You will see a big list. Find the UUID for the slave that you’re working on. Use the “more” pipe if the UUID for your particular slave scrolls off the screen:

xe pif-list params=uuid,host-name-label,device,management | more

Change the IP Address on the first slave:

xe pif-reconfigure-ip uuid=<UUID of host management PIF> IP=<New IP> gateway=<GatewayIP> netmask=<Subnet Mask> DNS=<DNS Lookup IPs> mode=<dhcp,none,static>

Then:

xe-toolstack-restart

Verify the new address with ifconfig, and/or ping it from a workstation.

Point the slave to the new Master IP Address:

xe pool-emergency-reset-master master-address=NEW_IP_OF_THE_MASTER

Repeat the commands above on all slaves.

On the Master:

xe pif-list params=uuid,host-name-label,device,management

xe pif-reconfigure-ip uuid=<UUID of host management PIF> IP=<New IP> gateway=<GatewayIP> netmask=<Subnet Mask> DNS=<DNS Lookup IPs> mode=<dhcp,none,static>

xe-toolstack-restart

DO NOT run the emergency-reset-master command on the Master.

Reboot the Master, then reboot the Slaves and verify that they can find the Master.
