RE: iSCSI 07-95 Comment 3 -Task Management

[Black_David@emc.com]

An implementation can choose when in time it chooses to
execute the task management command, but the effects visible to
the Initiator must be as if it was executed in CmdSN order
For example, if an Abort Task passes the task that it is
supposed to abort on a different connection and the Abort Task
has a higher CmdSN, the Target may immediately respond to the
Abort Task, but in that case, it MUST NOT execute the
"aborted" task when it arrives.  I agree that this could
use some further explanation in the draft.
