Provisioning | Provisioning setting of the volume: `Thin` or `Full`.
Provisioned capacity | Provisioned capacity of the volume, in gibibytes (GiB).
| NOTE: GiB is an industry-standard storage term. It is a base 2 notation instead of a base 10 notation.
Allocated capacity | Total capacity allocated to the volume.
Storage system | Storage system that hosts the storage pool to which the volume belongs.
Storage pool | Storage pool to which the volume belongs.
Snapshot storage pool | Storage pool from which to provision space for storing snapshots of the storage volume.
Sharing | Sharing setting for the volume:
Private | The volume can be used by only one server profile. Can be used to boot from SAN.

## Snapshots

Screen component | Description
--- | ---
Status icon | Status of the snapshot. See Icon descriptions for information about status icons.
Name | The name of the snapshot.
Revert | Opens the Revert dialog, which enables you to revert to the snapshot of the volume. See About snapshots for more information.
Create volume | Opens the Create Volume From Snapshot dialog , which enables you to create a volume from the snapshot. See About snapshots for more information. This will create a full copy based on the data in the snapshot. For large volumes, this can take a long time depending on storage system resources available for the copy action.

Storage paths menu
Connection | The profile connection name or the connection ID of the volume attachment.
Network | The network that is associated with the SAN in the volume attachment. The network name links to the network details on the Networks screen.
SAN | The SAN to which the volume is connected. The SAN name links to the SAN details on the SANs screen.

## Remove extra presentations dialog

This alert action is presented when HPE OneView detects volume access on a storage system was not granted by HPE OneView (extra presentation). Use the Remove extra presentations action to remove the extra presentation from the storage system. After you have removed extra presentations, managed volumes will only be accessable by servers whose server profiles contain attachments to the volume.

| NOTE: Do not use the Remove extra presentations operation if you have volumes under management of HPE OneView that are being accessed by servers that are not under management of HPE OneView, as this operation will remove their access to the storage system. The Remove extra presentations operation does not affect zoning or aliases.

Screen component | Description

Endpoint WWPN | The WWPN of the endpoint that is configured with access to the volume on the storage system, but not defined in any server profile volume attachment.
Endpoint | The HPE OneView name of the endpoint, if available.
Endpoint Alias | The endpoint SAN alias, if any exist on a managed SAN.
Zone | The SAN zones that contain the endpoint, if any exist on a managed SAN.
Online | Whether or not the endpoint is currently logged into the managed SAN; can be `Yes` or `No`.

## Remove access to volumes not managed by HPE OneView dialog

This alert action is presented either a server profile or a managed volume.

Server profile alert | The host entry on the storage system has extra initiators configured that HPE OneView has no record of. The Remove access to volumes not managed by HPE OneView operation removes the extra host entries.
Volume alert | A volume under management of HPE OneView has VLUNs that exist on the 3PAR storage system that do not exist in HPE OneView. Extra initiators (separate host entries on the storage array) or targets are present.. The HPE OneView fix operation removes the extra entries from the volume access. The Remove access to volumes not managed by HPE OneView operation removes the extra entries from the volume access.

| NOTE: The default scanning interval for these alerts is 4 hours.
