We have systems (16G HBA) connected to Brocade 16G switch through FC cables, and noticed that brocade switch tries to login over the HBA. What made me notice is - there was a remote login on the subject system here which had the wwpn aligned with wwn of the switch. Curious to know more on this.
Why does a switch logs into the system connected to its port ?
It should do this only during the initialisation phase. The PLOGI is being sent from the fabric nameserver to the hba to try and obtain some more information which it can use in reporting facilities. Nothing unusual.
