established.
A logical link is established when the subnet manager
recognizes the HCA during an HP Fabric Clustering System
probe.
None HCA is not
operational.
• 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 Clustering System software has not been
installed on the HP-UX host machine.
• A 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 HP Fabric Clustering System
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).
