interface cards employ serial-based clustering using two serial cluster links, and
provide Ethernet connectivity via one link.
For all controllers, the LEDs for the cluster ports have the following meanings. Note
that for serial cluster ports, only one of the LEDs (the link status LED) is used. For
Ethernet ports, both LEDs are used. See the following figures.
Activity LED
• Flashing green: Data activity
Link Status LED
• Solid green: Normal connection
• Solid yellow or off: Degraded connection
The following diagram illustrates the cluster Ethernet ports for Oracle ZFS Storage
ZS9-2 controllers.
