Replacing hot swap HBAs
Fiber Channel host bus adapters (HBAs) connected to a fiber array storage technology (FAStT) or DS4000
storage subsystem have a child device called a disk array router (dar). You must unconfigure the disk
array router before you can hot swap an HBA that is connected to a FAStT or DS4000 storage subsystem.
For instructions, see Replacing hot swap HBAs in the IBM System Storage DS4000 Storage Manager Version 9,

Overview
The PCIe2 LP 8 Gb 4-port Fibre Channel Adapter is a PCI Express (PCIe) generation-2, low-profile,
high-performance, x8 short form factor plus (SFF+) Host Bus Adapter (HBA). This adapter enables
multiple logical (virtual) connections to share the same physical port. Each logical connection has its own
resources and the ability to be managed independently. Each port provides single initiator capability over
a fiber link or provides multiple initiator capability with N_Port ID Virtualization (NPIV). The ports are
