Installing Firmware
Installing firmware involves loading, unpacking, and activating the firmware image on the switch. SANsurfer Switch Manager does this in one operation. To provide consistent performance throughout the fabric, ensure that all switches are running the same version of firmware.
The pending firmware version will differ from the active version during the brief period while the switch is resetting to activate the firmware. Firmware management tools enable you to install and activate new firmware.
During a hotreset operation, fabric services will be unavailable for a short period
