This counter tracks ABORTED COMMAND SCSI SENSE key errors on this LUN/flow, a general category covering commands the target aborted for reasons like a transport-layer error or an initiator-issued abort request, distinct from the more specific copy-abort case tracked separately. An admin seeing this climb on a flow should look for transport-level instability (like FC frame errors or a flapping link) on that specific path, since aborted commands often trace back to something disrupting communication mid-command rather than a data or media issue. A flow showing rising aborted-command errors alongside rising link-level frame-loss indicators on the same path would point clearly at a physical or transport problem rather than the storage array itself.
