Upgrading Effect on VSAN 4079
If you upgrade to NX-OS Release 5.0(4b), and you have not created VSAN 4079, the NX-OS software
will automatically create VSAN 4079 and reserve it for EVFP use.
If VSAN 4079 is reserved for EVFP use, the switchport trunk allowed vsan command will filter out
VSAN 4079 from the allowed list. In the following example, the allowed list appears on a separate line
following the command:
switch(config-if)# switchport trunk allowed vsan 1-4080
1-4078,4080
switch(config-if)#
If you have created VSAN 4079, the upgrade to NX-OS Release 5.0(4b) will have no affect on VSAN
4079.
If you downgrade to a release of NX-OS lower than NX-OS Release 4.1(x) after NX-OS Release 5.0(4b)
creates VSAN 4079 and reserves it for EVFP use, the VSAN will no longer be reserved.
Upgrading with IVR Enabled
An Inter-Switch Link (ISL) flap resulting in fabric segmentation or a merge during or after an upgrade
from Cisco MDS SAN-OS Release 2.0(x) to a later image where IVR is enabled might be disruptive.

FICON Nondisruptive Upgrade Path to MDS NX-OS Release 4.2(1b) (continued)
Upgrade Path
First upgrade to SAN-OS Release 3.3(1c), and then upgrade to NX-OS
Release 4.2(1b).
Use the interface shutdown command to administratively shut any Fibre
Channel ports on Generation 1 modules that are in an operationally down
state before nondisruptively upgrading from SAN-OS Release 2.0(2b) to
SAN-OS Release 3.0(2) or SAN-OS Release 3.0(3b), and then upgrade
to Release 3.3(1c). An operationally down state includes
or not-connected, SFP not present
output of a show interface command. When an interface is
administratively shut it will then show as
Interfaces that are currently up or trunking do not need to be shut down.
Upgrade to SAN-OS Release 3.0(2). Use the interface shutdown
command to shut all the ports operationally down and administratively up
on all the Generation 1 modules before nondisruptively upgrading to
Release 2.0(2b) and then upgrade to 1.3(4a).
FCIP connection flapping during the upgrade process resulting in fabric segmentation or merge.
ISL flap results in fabric segmentation or merge because of hardware issues or a software bug.
ISL port becomes part of PCP results in fabric segmentation or merge because of a port flap.
