HP Fabric Clustering System HP-UX Administrator's Guide, March 2008

The bottom LED indicates a physical link has occurred. A physical link requires that the drivers
on the attached HP Fabric host have been installed and are running.
If the HCA is not operational and needs to be replaced, see “Install HP Fabric Clustering System
Adapters” (page 36).

• The subnet manager did not recognize the HCA during an HP Fabric
Clustering System probe.
• The HP-UX host machine is not operational.
• HP Fabric software has not been installed on the HP-UX host machine.
• An HP Fabric HCA is installed in a slot in the HP-UX host machine,
but the cable is attached incorrectly or no cable is attached at all.
• The HCA is bad.
• The cable is bad.
• The switch port is bad (if the adapter is connected to a switch). Note
that if a switch port is bad, and (for some reason) you cannot use a
different port on the switch, you must replace the entire fabric switch.
However, you first should try turning the switch's power off and then
back on by unplugging both of the power cables.
• The HCA is connected to a non-operational adapter in the remote node
(in a node-to-node configuration).
HCA is not
operational.
