f. In the Display Metric group box, select how you want to display the access count: Number
or Percentage.
g. Select how you want to display read/write requests: Combined read/write, Separate
read, or Separate write.
h. Select the range for the I/O Time Columns: 0.008 to 32768 milliseconds. The default
range is 0.50 ms to 256 ms.
i. Select the range for the number of I/O operations (I/O Size Columns): 512 bytes to 16
megabytes. The default range is 4k to 1m.
6. Click Next to go to the Summary page, or click Finish to complete the wizard.

Creating a Physical Disk Space Report
The Physical Disk Space report displays physical disk space chunklets according to usage type.
Each usage type is shown in a different color on the same chart. The X-axis (category) represents
time, and the Y-axis (value) indicates the amount of disk space.
A table below the chart lists the following values:
Description Column
The date and time usage information was collected. (Shown only for values over a time interval
chart type.) Time
Chunklets allocated to logical disks and containing data that is currently accessible to the
system. Normal Used OK
Chunklets allocated to logical disks and containing data but inaccessible because they are
failed. Normal Used Fail
Chunklets currently initialized and available for use by logical disks. Normal Avail Clean
Uninitialized Chunklets to be cleaned. Normal Avail Dirty
Chunklets initialized but unallocated. These chunklets do not contain data and are failed. Normal Avail Fail
Chunklets currently used for sparing and containing data that is accessible by the system. Spare Used OK
Chunklets used for sparing but containing data that is currently inaccessible to the system
because they are failed. Spare Used Fail
Chunklets initialized and available for use, but only as spares. Spare Avail Clean
Uninitialized chunklets reserved for use as spares. Spare Avail Dirty
Chunklets reserved as spares but unusable because they are failed. Spare Avail Fail
For values at a specified time chart types, the table might also display the physical disk ID, cage
ID, cage size, magazine number, device number, device type, and disk speed (in thousands of
RPMs).
NOTE: The Speed number does not represent a rotational speed for the drives without spinning
media (SSDs). It is meant as a rough estimation of the performance difference between the drive
and the other drives in the system. For FC and NL drives, the number corresponds to both a
performance measure and actual rotational speed. For an SSD drive, the number is to be treated
as relative performance benchmark that takes into account in I/O per second, bandwidth, and
the access time.
