So far we (knock on wood) haven't had to use the backup system for production. Someone had the radical idea, however, that we actually needed a disaster recovery plan. I need a little (?) help with an aspect of the plan.
For this phase we are assuming that the damage is isolated to the production box (SystemA); that there is no structural damage to the environs; that everything else is copasetic. I port the configuration from SystemA to SystemB (the backup) in a save file (SAVCFG) automatically every night. (Forget to mention: Both boxes are supposed to be identical in all regards.) Security data (SAVSECDTA) is, also, pushed to the backup in a save file.
My question relates to user access via iSeries Access for Windows. Each PC user's IAW is configured to identify SystemA as the system to which they will access programs and data. Even though there are "only" about 20 PC's attached this way, I would rather not set up a connection to SystemB and, then, change each PC to access the backup system. Instead, I would rather change the identifier on the system (520) itself.
It looks like CHGNETA can be used to rename the systems. Is this all that I need to do? Or do I, also, need to change the IP address for the box? I seem to remember that there is a server somewhere that says, "IP address 10.0.0.4 = SystemB" etc. Is that the Domain Name Server (DNS)? And would I need to change that, too?
Thanks.
