Description (partial)

Symptom:
In extremely rare circumstances, it is possible that the creation of new IOA flow fails. The affected flow will be stuck in SENT_LOGO status.

<pre>
'show ioa internal interface ioa10/1 summary'

---- ----------------------- ---- ------------- ---- ---
FLOW HOST                    VSAN STATUS        COMP ACC
     TARGET
---- ----------------------- ---- ------------- ---- ---
1    50:06:0e:80:07:57:4b:47 30   SENT_LOGO     NO  WA
     50:06:0e:80:07:57:4a:47
</pre>

Any attempts to recreate the flow will result in the increase in the number of i-t create errors under the ioa interface statistics.

Conditions:
A flow with one or both of the affected ports was already configured and then deleted. An unknown error might have occurred during earlier flow deletion, causing some internal elements of earlier configuration to remain stuck.
