10. Number of MP failovers
11. Number of MP fatal errors
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.
