Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(8a)
OL-27554-05
Upgrading Your Cisco MDS NX-OS Software Image
• Ensure that you have a Supervisor-2A module (DS-X9530-SF2A-K9) installed in a MDS 9500
Series switch if you plan to use the Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet
(FCoE) (DS-X9708-K9).
• We recommend that you delete any SPAN configuration, Fibre Channel tunnel, or tunnel-ID map
configuration from your switch before you start the upgrade to NX-OS Release 5.2(1). You can save
the SPAN destination and SPAN target configuration and then reconfigure the SPAN session
following the upgrade. All SPAN destination and SPAN target ports are reinitialized after the
upgrade. To gather information about SPAN sessions and delete them, use the following commands
in this order:
– show incompatibility systems bootflash:image_name to display any incompatible
configurations
– show span session to check the current configuration for a SPAN session
– no span session session-number to delete a SPAN session
– show running-config | include fc-tunnel to check the current Fibre Channel tunnel
configuration
– no interface fc-tunnel y to delete a Fibre Channel tunnel on the switch that is the source for the
Fibre Channel tunnel
– show interface brief | include SD to check the current configuration for a SPAN destination
port configuration
– show interface brief | include ST to check the current configuration for a SPAN target port
configuration
– no fc-tunnel tunnel-map z interface x/y to remove an Fibre Channel tunnel map
– no switchport mode sd to negate the SPAN destination port mode for the SPAN destination port
– no switchport mode st to negate the SPAN target port mode for the SPAN target port
• If you are using IVR non-NAT mode, migrate to IVR-NAT mode before you upgrade to NX-OS
Release 5.2(1). 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 reestablish all applications that were stopped in step 1.
The network can now run in IVR-NAT mode.
