The switch memory is partitioned for two firmware images. One of these partitions contains the active firmware; that is, the firmware version that is in use. The other partition contains the inactive firmware which is not in use. The pending firmware is the firmware that will be activated at the next switch reset. The pending firmware can be the active firmware or the inactive firmware. When you install new firmware, that image becomes the inactive firmware and the pending firmware. Upon resetting the switch, this image becomes both the active and pending firmware.
Firmware management tools enable you to do the following:
* Install and activate new firmware
* Activate the pending firmware
* Change the pending firmware
Important:
* To provide consistent performance throughout the fabric, ensure that all switches are running the same version of firmware.
* The uploaded firmware will not be activated until the switch is reset. When the switch is reset, traffic will be disrupted.
* If you downgrade the firmware from 1.05 to 1.03 on a SANbox2-64 switch, you will lose your current switch configuration. The SANbox2-64 switch configuration will be reset to the factory defaults.
