Description
Item
•
Pool ID: Pool identifying number.
•
Usage Rate: Pool usage level as a percentage of the consumed V-VOL capacity
to the total V-VOL capacity.
•
Used Page Num: Number of pages used in V-VOL.
•
Page Status: Current page status of V-VOL.
◦ Discarding Zero Data: Zero data is being discarded and the pages are being
released.
◦ Discard Zero Data: XP Thin Provisioning is ready to discard zero data and
release pages. This status appears in blue bold italics until Apply is clicked.
◦ Stop Discarding Zero Data: XP Thin Provisioning is ready to stop discarding
zero data and releasing pages. This status appears in blue bold italics until
Apply is clicked.
◦ Releasing: Disassociation of the V-VOL from the pool is applied, and the page
is being released.
◦ A hyphen (-) appears when the page status is other than listed above.
Changes the emulation type OPEN-0V of the V-VOL to OPEN-V. Also, the contents
that were displayed in blue bold italics on the V-VOL group tree or V-VOL list are
deleted.
Emulation
Clicking the Emulation button, opens a window (see
Showing Two Emulation Modes” (page 34)
) in which Normal mode and Force mode
are selectable. These two options, Normal and Force, further restrict which V-VOLs
will be changed. Selecting Normal mode or Force mode determines the scope of
the emulation change process, as follows:
•
Normal mode: In Normal mode, XP Thin Provisioning V-VOLs that do not have
a defined LU path are changed. All OPEN-0V V-VOLs without a path assigned
are changed to OPEN-V.
•
Force mode: In Force mode, all XP Thin Provisioning V-VOLs, regardless of whether
an LU path is defined, are changed. All OPEN-0V V-VOLs are changed to
OPEN-V. Since the Force mode also changes XP Thin Provisioning V-VOLs on
which a LU path is defined, the emulation type recognized by the server will
change suddenly for these volumes. Use the Force mode only when you are sure
no problem will occur on the server, even if the emulation type is changed.
Therefore, it is possible that the LU cannot be recognized by the host and that
I/O stops. While the host is online and I/O occurs, it is strongly recommended
you avoid using Force mode.
If you use Force mode and change the emulation type already recognized by
the host, reconfigure the LU from the host so that the LU should be recognized
by the host.
These modes and the execution of the emulation process are not restricted by any
selection or highlighting of V-VOL entries in the list. All V-VOLs are considered for
an OPEN-V change during the emulation process.
Volume migration cannot be performed between volumes with different emulation
types. For example, volume migration is not available between an XP Thin
Provisioning V-VOL recognized as OPEN-0V and a normal volume.
