IVR non-NAT mode is deprecated in NX-OS Release 5.2(1). Note In dual SAN fabrics, IVR traffic can use one fabric while the other fabric is migrating. Only IVR traffic is disrupted during the migration. Regular traffic within the VSAN is not disrupted during the migration. To migrate to IVR-NAT mode, follow these steps: 1. Stop or divert all applications on servers that depend on IVR. - If CFS distribution is not enabled for IVR, then perform steps 2 through 4 on all switches where IVR is enabled. - If CFS distribution is enabled for IVR, then enter the ivr commit command following step 2, step 3, and step 4 to distribute the changes to other switches. 2. Deactivate the IVR zone set by entering the no ivr zoneset activate command. 3. Enable IVR NAT by entering the ivr nat command. 4. Activate the IVR zone set by entering the ivr zoneset activate command. 5. Start or re-establish all application that were stopped in step 1. The network can now run in IVR-NAT mode. General Upgrading Guidelines Follow these general guidelines before performing a software upgrade: • Review the nondisruptive upgrade path to release 5.2(2) in Table 11. • Install and configure dual supervisor modules before the upgrade. • Issue the show install all impact upgrade-image CLI command to determine if your upgrade will be nondisruptive. • Be aware that some features impact whether an upgrade is disruptive or nondisruptive: - Fibre Channel Ports: Fibre Channel ports can be nondisruptively upgraded without affecting traffic on the ports. See Table 11 for the nondisruptive upgrade path for all NX-OS and SAN-OS releases. Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(2) 16 OL-25090-02
