Power down the SSM and perform the downgrade. Bring up the SSM with the new bootvar set to the 2.x SSI image. • Downgrade the SSI boot images on the SSMs on the switch to a release version supported by your Cisco SAN-OS release. Refer to the Cisco MDS SAN-OS Release Compatibility Matrix for Storage Service Interface Images. • SSM intelligent services traffic switching on SSM ports is disrupted on upgrades or downgrades. • Fibre Channel switching traffic on SSM ports is not disrupted under the following conditions: - All SSM applications are disabled. Use the show ssm provisioning CLI command to determine if any applications are provisioned on the SSM. Use the no ssm enable feature configuration mode CLI command to disable these features. - The EPLD version on the SSM is at 0x07 or higher. Use the show version module slot epld CLI command to determine your EPLD version.
