Downgrading from NX-OS 4.x to SAN-OS 3.x
If you need to downgrade from an NX-OS 4.x image to a SAN-OS 3.x image, make sure that you enter
the system health check bootflash command on the switch running NX-OS 4.x before you downgrade
to SAN-OS 3.x. The system health check bootflash command, which is available starting in NX-OS
4.1(1b), ensures that the available free space is taken into account properly.
