Description

Item

Select the Pool Name check box, and then enter the pool name.

Pool Name

Prefix: Enter the alphanumeric characters, which are fixed characters of the
head of the pool name. The characters are case-sensitive.

Initial Number: Enter the initial number following the prefix name, which can
be entered up to 9 digits (when a pool is selected, the pool name appears
in the Prefix text box by default. When multiple pools are selected, the initial
number from the set number to the maximum number of the digit number is
automatically set).

You can enter up to the 32 characters including the initial number. The initial
number should be 9 or less digits.

Examples:

When 1 is set in the Initial Number field, number 1 to 9 is automatically given
to the pool name.

When 08 is set in the Initial Number field, number 08 to 99 is automatically
given to the pool name.

When 098 is set in the Initial Number field, number 098 to 999 is
automatically given to the pool name.

Select the Warning Threshold check box, and then enter a threshold. The
minimum threshold is the pool usage rate plus 1%. The maximum threshold is
100%.

Warning Threshold

For Fast Snap or Snapshot, you cannot change the setting of this function.
Snapshot:

Check Warning Threshold and enter a threshold.

You cannot set this item if the result of the following calculation exceeds 95:

(used-pool-capacity/pool-capacity) * 100 (%)

Select the Depletion Threshold check box, and then enter a threshold. The
minimum threshold is the pool usage rate plus 1%. The maximum threshold is
100%.

Depletion Threshold

If you change the Fast Snap or Snapshot pool, you cannot set this item.

CAUTION:

If you want to change multiple parameters for a pool two or more times, wait until

the current task finishes, and then change the next settings. If you attempt to change settings before
the current task finishes, only the settings in the next task will be applied, so the result might be
different from what you expected.
If you use Thin Provisioning, Smart Tiers, Fast Snap, or Snapshot for the pool in which only one of
the user-defined thresholds is set, the system threshold (fixed at 80%) is enabled. When the Edit
Pools window opens on the pool to which the system threshold is enabled, the lower value of the
user-defined threshold or the system threshold is assigned to the Warning Threshold, and the other
value is assigned to the Depletion Threshold. In this case, the text box of the assigned system
threshold is blank. In the pool for which the system threshold is enabled, if either of the thresholds
is changed, the unchanged threshold is defined as follows:

If you change only Warning Threshold, the higher value of the user-defined threshold or the
system threshold (fixed at 80%) is defined as Depletion Threshold.

If you change only Depletion Threshold, the lower value of the user-defined threshold or the
system threshold (fixed at 80%) is defined as Warning Threshold.

In this case, note that the reported SIM code number changes when the pool usage capacity
exceeds the threshold. If the threshold changes once, the system threshold is not enabled again.

Edit Pools Confirm window

Confirm proposed settings, name the task, and then click Apply. The task will be added to the
execution queue.
