Booting from a specified flash

Procedure
  1. To reboot from primary flash, use the boot system flash primary command.

    This command allows a boot sequence that includes the complete set of self-tests.

  2. To reboot from secondary flash, use the boot system flash secondary command.

    This command allows a boot sequence that includes the complete set of self-tests.

The following example shows use of the command to reboot the switch from secondary flash when there are no pending configuration changes in the running-config file. Typing either a [y] or [n] at the second prompt initiates the reboot operation.
