Blade swapping

Blade swapping allows you to swap one blade with another of the same type; in this way, you can
perform a FRU replacement with minimal traffic disruption. The entire operation is accomplished
when the bladeSwap command runs on the Fabric OS. The Fabric OS then validates each
command before actually implementing the command on the enterprise-class platform. If an error
is encountered then blade swap quits without disrupting traffic flowing through the blades. If an
unforeseen error does occur during the bladeSwap command, an entry will be made into the
RASlog and all ports that have been swapped as part of the blade swap operation will be swapped
back. On successful completion of the command, the source and destination blades are left in a
disabled state allowing you to complete the cable move.
Blade swapping is based on port swapping and has the same restrictions:

NOTE
Only the FC ports will be swapped on an FX8-24 blade. GE and VE ports will not be swapped.

Guide.

Ports that have been swapped cannot be moved to another logical switch.
Ports with area OxFE or OxFF addresses cannot be swapped when FMS mode is enabled.
You can use the portSwapShow command to display information about swapped ports in a
switch.
You can use the portSwap command to disable the port-swapping feature. You cannot use the
portSwap command after this feature is disabled. The enabled state of the port-swapping
feature is persistent across reboots and power cycles. Enabling and disabling the
port-swapping feature does not affect previously executed port-swapping operations.
Shared area ports cannot be swapped.
Ports or blades with area OxFE or OxFF addresses cannot be swapped when FMS mode is
enabled.
Ports that are part of a trunk group cannot be swapped.
GbE ports cannot be swapped.
Swapping ports between different logical switches is not supported. The ports on the source
and destination blades need to be in the same logical switch.
Undetermined board types cannot be swapped. For example, a blade swap will fail if the blade
type cannot be identified.
Blade swapping is not supported when swapping to a different model of blade or a different
port count. For example, you cannot swap an FC8-32 blade with an FC8-48 port blade.
Blade swapping is not supported on application blades.
