Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(1)
OL-25090-01
Upgrading Your Cisco MDS NX-OS Software Image
Upgrading Guidelines Specific to NX-OS Release 5.2(1)
Follow these guidelines when upgrading to Cisco MDS NX-OS Release 5.2(1):
•
Upgrade to NX-OS Release 5.2(1) before you install any Generation 4 module in an MDS 9500
Series switch. Generation 4 modules include the FCoE module and the 32-port and 48-port 8-Gbps
Advanced Fibre Channel modules. (See the
“New Hardware” section on page 22
for a list of
Generation 4 hardware.) NX-OS Release 5.2(1) is needed for the switch to recognize the new
hardware.
•
Perform a full switch reload on an MDS 9509 or MDS 9506 switch after you install NX-OS Release
5.2(1) and install any Generation 4 module, including the FCoE module. The switch reload is
required for the new hardware to come up. Once you perform the switch reload, the fabric mode
changes to support the Generation 4 hardware. Because of the changed fabric mode, you cannot
subsequently perform a nondisruptive software downgrade from NX-OS Release 5.2(1). For
additional information, see the
“Downgrading Guidelines Specific to NX-OS Release 5.2(1)”
section on page 18
•
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-tunne
l
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.
