Upgrading Your Cisco MDS SAN-OS Software Image Send documentation comments to [email protected] - SSM: Intelligent services traffic on the SSM, such as SANTap, NASB, and FC write acceleration, is disrupted during an upgrade. SSM Fibre Channel traffic is not. - 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. 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. - 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 16 for these instructions. - FICON: If you have FICON enabled, the upgrade path is different. See Table 7. Use Table 6 to determine your nondisruptive upgrade path to Cisco SAN-OS Release 3.2(1). Find the image release number you are currently using in the Current column of the table and use the path recommended. 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.
