processing. Numbers are the raw counter values, not computed per sample.

The syntax for the command is:

rawstat [interval [count]]

interval is the number of seconds between samplings. The default is one

second. count is the number of samples to make; the default is to sample

indefinitely.

The output consists of ASCII text delimited by carets. The fields are:

1. PSD device name

2. Sample number

3. Sampling interval

4. Number of targets

5. Current active target

6. Number of I/O sizes

7. First I/O size (power of 2)

8. Number of I/Os queued (includes raw)

9. Number of raw I/Os queued

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.
