Description
Displays information about the V-VOL capacity.
Total: Displays the V-VOL capacity.
Reserved: Displays the reserved capacity of the V-VOL.
The displayed value of Reserved might be larger than the displayed value of
Total due to following reasons:
◦
Reserved displays the reserved capacity that is rounded up on each page.
◦
If the emulation type is 3390-A, the mapped capacity of V-VOL includes
the capacity of control cylinders (7 Cyl is required per 1,1 13 Cyl).
◦
The mapped capacity of V-VOL for Thin Provisioning includes the capacity
of control information (168 MB is required per 3,145,548 MB).
Used: Displays the sum of the mapped capacity and the reserved capacity.
The displayed value of Used might be larger than the displayed value of Total
due to following reasons:
◦
Used displays the sum of the mapped capacity and the reserved capacity
that is rounded up on each page.
◦
If the emulation type is 3390-A, the mapped capacity of V-VOL includes
the capacity of control cylinders (7 Cyl is required per 1,1 13 Cyl).
◦
The mapped capacity of THP V-VOL includes the capacity of the control
information (Requires a maximum of 168 MB per 3,145,548 MB).
If used capacity is referenced during I/O or copy processing by software
such as Business Copy or Continuous Access Journal, the used capacity
displayed might be different from the actual capacity even if the full
allocation is enabled on the V-VOL. This is caused by a gap between the
times that information is gathered about the mapped capacity and the
reserved capacity.
Used(%): For the entire capacity of V-VOL, this item displays percentages of
the sum of the mapped capacity and the reserved capacity.
Used(%) is obtained by dividing the total of the user data and control
information by the user area capacity. For an LDEV such as a TSE-VOL, where
the ratio of the control information is high relative to the user area, Used(%)
may exceed 100 %.

Tier1: Displays the used capacity of tier 1.
A hyphen (-) is displayed if the logical volume is a not a V-VOL of Smart Tiers
or Smart Tiers Z.

A hyphen (-) is displayed if tier 2 does not exist or if the logical volume is a
not a V-VOL of Smart Tiers or Smart Tiers Z.
Tier3: Displays the used capacity of tier 3.
A hyphen (-) is displayed if tier 3 does not exist or if the logical volume is a
not a V-VOL of Smart Tiers or Smart Tiers Z.
The reserved capacity is not included in the used capacity for each tier of the
V-VOL. Therefore, the Used value in the Capacity column might not correspond
with the Used Capacity value.

Provisioning Z or Smart Tiers Z V-VOL.
Displays the CLPR ID.
