problem.
The number of destination address routing failures. Destination
address routing is performed through host networking. An
CNumber of destination address routing
failures
address routing failure indicates a network configuration
problem.
The number of session logouts performed by the initiator.INumber of session logouts
The number of session state machine transitions to the online
state.
INumber of session state machine transitions
to online state
The number of session state machine transitions to the transient
state. A session enters the transient state when:

• The current active connection dies.
• Task Management cold reset is in progress.
• Session logout has occurred.
• Flow control has been enabled.
The number of session state machine transitions to the offline
state.
INumber of session state machine transitions
to offline state
The number of requests from the network interface driver to
enable session flow control for I/Os. This might be the result

control
of excessive I/Os through a session that impacts general
network performance.
The number of requests from the network interface driver to
disable session flow control for I/Os.
INumber of requests to disable session flow
control
The number of asynchronous requests from the target to perform
a session logout.
INumber of async events "target will drop
all connections" received
The number of PDU send attempts that failed. This could be
the result of resource allocation problems or target connectivity
issues.

failures
The number of session state machine unexpected events
received while in the online state. The unexpected events will

session online state
be ignored, and will not impact operations. If this value is
non-zero, an investigation into the cause of the unexpected
events should be initiated.
The number of session state machine unexpected events
received while in the transient state. The unexpected events

session transient state
will be ignored, and will not impact operations. If this value
is non-zero, an investigation into the cause of the unexpected
events should be initiated.
The number of session state machine unexpected events
received while in the offline state. The unexpected events will

session offline state
be ignored, and will not impact operations. If this value is
non-zero, an investigation into the cause of the unexpected
events should be initiated.
