recommended.
Note On an MDS 9222i switch, an upgrade from SAN-OS Release 3.2(x), Release 3.3(1), or Release 3.3(1a)
to Cisco MDS NX-OS Release 4.1 fails when there is an active FC-Redirect configuration (created by
Cisco SME or Cisco DMM applications) on the switch. An active FC-Redirect configuration is defined
as:
FC-Redirect configuration for hosts or target connected locally
•
FC-Redirect configuration created by application running on that switch.
•
If an upgrade is attempted when an active configurations is present, the switch will go into a disruptive
upgrade.
On an MDS 9222i switch, if SANTap or Invista is provisioned on a Storage Services Module (SSM) in
Note
slot2, then an In Service Software Upgrade (ISSU) to NX-OS Release 4.1(1b) is not supported. The
upgrade to NX-OS Release 4.1(1b) is supported if you set boot variables, save the configuration, and
reload the switch. If the switch is running SAN-OS Release 3.3(1a) or earlier, first upgrade to SAN-OS
Release 3.3(1c) and then upgrade to NX-OS Release 4.1(1b).

Gigabit Ethernet Ports: Traffic on Gigabit Ethernet ports is disrupted during an upgrade or
–
downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MPS-14/2 module,
the MSM-18/4 module, and the MDS 9222i switch. Those nodes that are members of VSANs
traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators
connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the upgrade is
in progress.
Inter-VSAN Routing (IVR): With IVR enabled, you must follow additional steps if you are
–
upgrading from Cisco SAN-OS Release 2.1.(1a), 2.1(1b), or 2.1.(2a). See the
IVR Enabled" section on page 23
– FICON: If you have FICON enabled, the upgrade path is different. See
to determine your nondisruptive upgrade path to Cisco MDS NX-OS Release 4.1(1b), find
for these instructions.
