🌸 DESCRIPTION 🌸

okay so this routine checks whether there is an outstanding host link attention event during the discovery process with the vport. The way she does it? by reading the HBA's Host Attention (HA) register. 👑

If there is any host link attention events during this vport's discovery process, here's the whole situation: the vport shall be marked as FC_ABORT_DISCOVERY, a host link attention clear shall be issued if the link state is not already in host link cleared state, and a return code shall indicate whether the host link attention event had happened. 💥

note note note: if either the host link is in state LPFC_LINK_DOWN or vport state in LPFC_VPORT_READY, the request for checking host link attention event will be ignored, and a return code shall indicate no host link attention event had happened. periodt.

🔥 Return codes

  • 0 — no host link attention event happened.
  • 1 — host link attention event happened.
