Upgrading Your Cisco MDS SAN-OS Software Image Send documentation comments to [email protected] - 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 "Upgrading with IVR Enabled" section on page 17 for these instructions. - FICON: If you have FICON enabled, the upgrade path is different. See the "FICON Supported Releases and Upgrade Paths" section on page 17. Use Table 6 to determine your nondisruptive upgrade path to Cisco SAN-OS Release 3.3(4a). Find the image release number you are currently using in the Current column of the table and use the path recommended. Note On an MDS 9222i switch, an upgrade from SAN-OS Release 3.2(x), Release 3.3(1a), or Release 3.3(1c) to SAN-OS Release 3.3(4a) 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. Note The software upgrade information in Table 6 applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and SSM intelligent services traffic.
