Hello.,
As part of an organization change we need to change the IP address of everything in our environment, to a new corporate network range. I was wondering if our plan to REIP the primary routable interface on each of our NetApp’s was solid. Here is the typical controller-
Type | Controller | Interface | Network Address | Network Mask | Type | Status | In/Sec | Out/Sec | Protocols |
Active/Active Controller | irv-gdc-san1a.corp.myco.com | vif1-96 | 10.1.96.100 | 255.255.255.0 | VIF | Up | 694780 | 1745400 | CIFS |
Active/Active Controller | irv-gdc-san1a.corp.myco.com | losk | 127.0.20.1 | 255.0.0.0 | Unknown | Up | 0 | 1 | LOOPBACK |
Active/Active Controller | irv-gdc-san1a.corp.myco.com | vif2-230 | 10.1.230.50 | 255.255.255.0 | VIF | Up | 52099700 | 23208100 | iSCSI |
Active/Active Controller | irv-gdc-san1a.corp.myco.com | vif2-231 | 10.1.231.50 | 255.255.255.0 | VIF | Up | 2099880 | 1475370 | NFS |
Active/Active Controller | irv-gdc-san1a.corp.myco.com | vif2-232 | 10.1.232.50 | 255.255.255.0 | VIF | Up | 75679 | 6013 | NFS |

The A record points to 10.1.96.100, and the tentative plan was to -
- Add new VLAN to existing VIF1 interface. [vlan create vif1 26]
- Add new IP Address (10.228.26.100) to new VLAN [Ifconfig Vif1-26 10.228.26.100 netmask 255.255.255.0]
- Verify connectivity by testing CIFS / RPC to new IP address
- Change A record(s)
- Confirm network traffic [netstat -I vif1-96 -w 1 –x]
- Change default route
- Confirm network traffic [netstat -I vif1-26 -w 1 –x]
- Remove existing vif1-96 VLAN
