SG Changing IP

[Jason Ng Teng Po]

Hi,

My customer asked me is it possible to change the production LAN, package IP for 2 nodes cluster without downtime?

If it needs down time, please kindly advice me what are the steps I need to do in order to change the IP smoothly

environment is HP-UX 11.31 with 2 node SG with 3 package

Basicaly the simple answer is you need to take the package down, and modify the package control script, unless you are using mnodular packages in which case you need to edit and apply the modular package configuration file
Read the Managing Servioeguard manual for your version http://docs.hp.com/en/ha
This will redirect you to the new location, and sim,ply choose Serviceguard, then the manual for the revision you are using

Any resource modificatios to the package should be carried out with a downtime.

#cmhaltpkg

Do the modifications

#cmrunpkg -n

Chapter 6 of Managing Serviceguard manual contains required information.

as me known, if it changed the pacakge IP, it means to re-configure the cluster!
