12... Per-target I/O statistics in tuples, or groups of two numbers. (The

number of targets is indicated in field 4.) Each tuple consists of the

following fields for each target:

• SCSI I/Os queued

• Transient failures

Note that the “SCSI I/Os queued” numbers are for the underlying disk,

not the partition. PSD devices that share the same underlying disk will

share the same numbers here.

12+$4*2... I/O statistics in quads, or groups of four numbers. (The number of

quads appears in field 6, “Number of I/O sizes”). Each quad consists of the

following fields for each I/O size:

• Minimum latency

• Maximum latency

• Count of I/Os

• Total latency for all I/Os

The minimum and maximum latency are reset every interval. Latencies are in

microseconds.
