Abstract
An application may query a fabric driver to obtain a list of devices visible through a fabric host adapter port(s). The fabric driver may obtain the list of devices by querying a fabric name server. For direct attach devices, device nodes may be created during driver attach. However, for fabric topologies the fabric driver is queried on-demand to provide a list of devices visible through the fabric host adapter port(s). A user (e.g. through an application) may then select devices from this list to be onlined. An indication of the fabric devices that are online for the host system are stored in a persistent repository. Following a reboot of the host system, the persistent repository may be read to determine which fabric devices were online prior to the reboot. The fabric devices that were online prior to the reboot to be may again be brought online for the host system.
