Hi All
I have two Pseries servers with AIX 5L as operating systems. HACMP cluster was there. For some reasons I have to change IP addresses of Servers. So How could I do it?

Hi

you can use smitty tcpip to change the service IP address, and those changes should be reflected in the /etc/hosts file on both nodes with their appropriate aliases

then try to sync the cluster both nodes

smitty hacmp > c-spoc > communication interface management > configure communication Interfaces..... to manage interfaces on all nodes from one node

for service address, use

smitty hacmp > initialization and standard configuration > configure resources to make highly available > configure service ip labels/addresses > change/show a service ip label/address

for boot address:

smitty hacmp > extended topology configuration > configure hacmp networks > change show a network in the hacmp cluster (also for disk hb)

and for persistent address:
smitty hacmp > extended topology configuration > Configure hacmp persistent node ip label/addresses



I'm sure there are fastpaths for this
