The Login Response and
Status Is Sent Through the

Status Block
After LOGIN is processed, the host processes the correct command agents.
Figure 72. Typical Login Process
Write to the initiator node_ID, which is managed by the command_agent, through the agent control register
(50h). Write the appropriate agent number into AgtNmb, log in Node_ID into NodeID, and WrNdID. The host
has the ability to automatically respond with a conflict error to accesses from initiators that have not correctly
logged in.
Activate the COAF_agent by setting CAg(n)Vld on the ORB fetch control register (44h) for initiator access.
All initiators can send QUERY LOGIN ORBs at any time to check status of an ongoing LOGIN. This process
is the same as LOGIN except there is no need to check EUI-64. Other management ORBs are processed
the same way.
Figure 7-2 shows an example of the process.
