The network manager has not really given us enough information. But at a DR meeting this week he stated in the DR networks they had to have separate IP addresses and separate DNS servers and don't want to extend the VLAN between the 2 networks. He also said the mainframe folks should 'just use hostnames' and 'not code any IP addresses'. I don't think he has a clue what is in PROFILE TCPIP or TCPIP DATA. We will try to get some more information out of the folks who report to him.

If so, maybe you could define multiple interfaces (some for prod, some for DR), activating the ones appropriate for the situation, but use VIPA to retain a consistent IP address for your systems from a DNS point of view.

Rachel Joy Scott "Smith, Ann (ISD, IT)" <[EMAIL PROTECTED] To tford.com> [email protected] Sent by: Linux on cc 390 Port <[EMAIL PROTECTED] Subject IST.EDU> Changing IP addresses at time of DR 07/10/2008 11:22 AM Please respond to Linux on 390 Port <[EMAIL PROTECTED] IST.EDU> In our current DR scenario we PPR copy our mainframe dasd (zOS, zVM and zLinux). We IPL at the DR site for tests and real disaster. The procedures have gotten more simplified over the years. That may be about to change. In the new network plan we are being told we will need to use different IP addresses in the local production network, in the DR test network and in the real disaster production network. So 3 sets of addresses and 3 DNS servers. So now we need to figure out how to change the IP addresses for the zVM systems and the linux guests. Has anyone else had to deal with this sort of scenario?
