Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.1(2a) Starting with Cisco MDS SAN-OS Release 3.0(1), the SSM front panel ports can no longer be configured in auto mode, which is the default for releases prior to Release 3.0(1). Note To avoid any traffic disruption, modify the configuration of the SSM ports as described below, before upgrading a SAN-OS software image prior to Release 3.1(2a). For more information on upgrading SAN-OS software, see the "Upgrading Your Cisco MDS SAN-OS Software Image" section on page 9. If the configuration is not updated before the upgrade, the installation process for the new image will automatically convert all ports configured in auto mode to Fx mode. This change in mode might cause a disruption if the port is currently operating in E mode. To upgrade the image on your SSM without any traffic disruption, follow these steps: Step 1 Verify the operational mode for each port on the SSM using the show interface command: switch# show interface fc 2/1 - 32 fc2/1 is up Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Release 3.1(2a) 14 OL-12208-03
