My question is that can I reassign the ownership of the IP aliase to other node without shutting down the TCPIP ?
Solved! Go to Solution.

SolutionDepending on how the alias address was assigned, if it was assigned to the other node as a "home alias", then this address will migrate to that node when it boots up. This depends of course on no more connections to the alias on the current node.
Please email me if you need clarification.

Re: HP TCPIP Alias
your IP alias (failSAFE IP address 203.102.145.10) has not been defined with a HOME interface. HOME interfaces are designated with a '*' preceeding the 'inet' string in the ifconfig -a output.
To define an alias with a home interface, use:
$ ifconfig we0 home alias 203.102.145.10
You can easily (temporarily) remove an alias from a specific interface. It will then fail over to another interface, which has this alias defined:
$ ifconfig we0 -alias 203.102.145.10
Please keep in mind, that sessions established using this alias IP address may be terminated, if the alias will have to fail over to another node in the cluster.
Once the alias has moved to the desired interface/node, you can re-add it on the interfaces, from which you temporarily removed it.
Volker.

Re: HP TCPIP Alias
It worked and it is that simple.
