OLS
See offline sequence.
operating state (director)
The operating states are described as follows:
• Online—when the director is set online, an attached device can log in to the director if the
port is not blocked. Attached devices can communicate with each other if they are
configured in the same zone.
• Offline—when the director is set offline, all ports are set offline. The director transmits
the offline sequence (OLS) to attached devices, and the devices cannot log in to the
director.
operating state (port)
Valid states include Online, Offline, Testing, Beaconing, Invalid Attachment, Link Incident,
No Light, Not Operational, Port Failure, Segmented E_Port.
operating status (director)
The operating status depends on hardware component failures, which are indicated by alert
symbols that display in HAFM application views.

provided through an open systems interconnection (OSI) device attached to a director or
switch port.
