Replacing Fibre Channel adapters using hot swap
When hot swapping fibre channel adapters, be aware that device-related software for the storage devices
might have additional devices (for example, the dar device associated with the FAStT or DS4800) that
need to be removed. Refer to specific storage device documentation for information about how to remove
these additional devices.
The new adapter has a unique worldwide port name (WWPN). Check the zoning and LUN assignments
to ensure that the new adapter will function as expected.
