Cisco MDS 9700 Series User Manual

8.4(2a) or later on Cisco MDS 9718 Multilayer Director. Use the show version command to view the
current image on the system.
To upgrade an image version on the switch, refer the Cisco MDS 9000 NX-OS Software Upgrade and
Downgrade Guide, Release 8.x guide.
• The migration procedure must be performed during a schedule maintenance period only.
• Nondisruptive backward migration procedure (migrating from a Supervisor-4 Module to a Supervisor-1E
or Supervisor-1 Module) is not supported. Backward migration is disruptive (power off and power on
the switch).
• In a dual supervisor module scenario, ensure that the standby supervisor module is in the HA-standby
state. If the standby supervisor does not come up in the HA-standby state, then physically remove the
standby supervisor module and initiate the migration on the active supervisor module. Use the show
module command to view the Active and Standby supervisor modules.
• After the migration procedure, your current active supervisor module will be in standby state and your
current standby supervisor module will be in active state.
• Do not reload or manually insert or remove any I/O or crossbar fabric switching modules after initiating
the migrate sup kickstart < supervisor4-kickstart-image > system < supervisor4-system-image >
command. Any removal or insertion of I/O or Crossbar Fabric-1 Switching Modules must be done before
initiating the migration process or after the migration is completed.
• Configuration mode is blocked during the migration procedure to prevent any changes.
• You cannot press Control+C to cancel the migration procedure until 45 minutes have elapsed after
executing the migrate sup kickstart < supervisor4-kickstart-image > system <
supervisor4-system-image > command.
• Use the show logging onboard migration status command on any management session to display the
status of the migration. You can use this command during the migration or after the migration is complete.
• In the system messages (system messages displayed on the console during the migration process) and
the show module command output, Supervisor-1 Module (DS-X97-SF1-K9) and Supervisor-1E Module
(DS-X97-SF1E-K9) are displayed as Supervisor-3 Module.
• Perform the Fabric-1 to Fabric-3 module migration after the Supervisor-1/Supervisor-1E to Supervisor-4
Module migration is completed. A mix of Fabric-1 with Supervisor-4 Modules or Fabric-3 with
Supervisor-1/Supervisor-1E Modules is not supported.
• Ensure that the switch release version and the targeted migration release version is same. Use the show
version command to view the version of the Cisco MDS NX-OS software on the switch.
• If you are using a Supervisor-4 Module for migration that has been already used in a previous MDS
setup, ensure that the Supervisor-4 module has sufficient space on bootflash for copying both the system
and kickstart images before the migration.
• The following table lists the supported release versions for migrating to Supervisor-4 Modules on the
Cisco MDS 9700 Series of Multilayer Directors.
