Port States
The port operational state refers to actual port state and not the administrative state
you may have assigned. The port administrative state refers to the user-requested
state. Refer Port Operational States to for more information. Port administrative
states have two forms: the configured administrative state and the current
administrative state. Refer Port Administrative States to for more information.
I/O Stream Guard The I/O Stream Guard option suppresses the Registered State
Change Notification (RSCN) messages on a port basis. I/O Stream
Guard should be enabled only on ports connected to initiator
devices. To change, click in the field and select an option from the
drop-down list. The options are:
• Enable - suppresses the reception of RSCN messages from other
ports for which I/O Stream Guard is enabled.
• Disable - allows free transmission and reception of RSCN
messages.
• Auto - suppresses the reception of RSCN messages when the
port is connected to an initiator device with an HBA. The default
is Auto.
Device Scan The Device Scan feature queries the connected device during login
for FC-4 descriptor information. Disable this option only if the scan
creates a conflict with the connected device.
