     DSECT NAME - IODSZI
     FUNCTION - Map a Monitor record.

     NAME - MRIODSZI
     DESCRIPTIVE NAME - Monitor Sample Record
                        Domain 6 - I/O Domain
                        Record 24 - SCSI Device Activity
     DESCRIPTION - Describes I/O activities of an emulated SCSI device.
                   A separate record is generated for each online device
                   enabled for monitoring.
     NOTES:

       If IODSZI_PTHEXTVER = 1 then PCM Path Statistics are available.
         - See IODSZI_PTHEXTSZ for the size of the data for each path,
           IODSZI_PTHEXTCT for the number of paths, and IODSZI_PTHEXTOF
           for the offest to the beginning of the PCM Path Statistics.

       The Path Transfers (IODSZI_PTH1XFERS to IODSZI_PTH8XFERS) sum
       may be greater than the Disk Transfers (IODSZI_DSKXFERS) for
       the following reasons:
        (1) Retrying I/O will increment the path transfers count for
            the specified path, but not the disk transfers count.
        (2) Sending IOCTL commands does not cause a disk transfer, but
            the path transfers count is still incremented, as a path
            is used to send the IOCTL command.
