Table 4 Transport Statistics (continued)
Description of FieldCLiscsiutil Statistic
The number of iSCSI SendTargets commands sent to iSCSI
targets. The iSCSI SendTargets command is used in discovery
INumber of SendTargets commands issued
sessions to determine normal targets behind a target port
(portal group). Normal sessions can then be established with
the normal targets for I/O operations.
The number of iSCSI SendTargets command attempts that
failed. The failure is due to an operation time-out which is seen
as an incomplete I/O operation.
DNumber of SendTargets commands issued
that failed
The number of iSCSI SendTargets command attempts that failed
as a result of a received key parse error. This failure would
result from invalid keys received from the target device.
TNumber of SendTargets response parse
failures
The number of times iSCSI LUNs with multi-level LUN
addressing are skipped from registering with legacy I/O tree
INumber of unclaimed legacy LUNs
infrastructure. In pre-11i v3 releases, multi-level LUN addressing
was not supported. This is why such LUNs are not registered
with legacy I/O tree.
The total number of I/O requests that failed as a result of a
session being offline or task management being in progress.
This is a global total over all sessions.
D/CI/Os failed due to ssn offline or TM under
progress
The time that the statistics were last cleared. This defines the
period of time to which the statistics can be applied, and
ITime when statistics were last cleared
therefore can be used for averaging the statistics. Because
each system is different, separate statistic rates can be
determined on a per-system basis and used to identify load
changes.
Transport Session Statistics
The number of session open requests received in the transport
layer from upper layer protocols (SCSI).
INumber of session opens from upper layers
The number of session close requests received in the transport
layer from upper layer protocols (SCSI).
INumber of session closes from upper layers
The number of time the ioconfigd (I/O Configuration Daemon)
initiates a session reopen.
INumber of session reopens
The number of session open requests received in the transport
layer while in the reopen context. A reopen is a component
of session error recovery.
INumber of session opens in the reopen
context
The number of session open requests received, while in a
reopen context, that were aborted because the session is
already open.
INumber of session opens aborted in the
reopen context
The number of session close requests received, while in a
reopen context, that were aborted because the session is
already closed.
INumber of session closes aborted in the
reopen context
The number of session open requests received that failed. The
failure could have been due to unavailability of resources, or
problems with the connection to the target.
CNumber of connection opens that failed
The number of times logins were successfully redirected to
different target addresses.
INumber of successful login redirections
The number of TCP connections that have been unexpectedly
dropped. This is typically a result of connectivity problems. If
CNumber of async events received for dead
connections
a problem is persistent, a network infrastructure engineer
should be contacted.
