Replacing Fibre Channel adapters by using hot swap
When hot swapping Fibre Channel adapters, be aware that device-related software for the storage devices
might have extra devices (for example, the disk array router (dar) device that is associated with the fiber
array storage technology (FAStT) or DS4800) that need to be removed. For more information, see the
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 logical unit
number (LUN) assignments to ensure that the new adapter functions as expected.
Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. To check for operating system and partition requirements, see one of the following links:
