[ aws . storagegateway ]

describe-cached-iscsi-volumes

Description

Returns a description of the gateway volumes specified in the request. This operation is only supported in the cached volume gateway types.

The list of gateway volumes in the request must be from one gateway. In the response, Storage Gateway returns volume information sorted by volume Amazon Resource Name (ARN).

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-cached-iscsi-volumes
--volume-arns <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--volume-arns (list)

An array of strings where each string represents the Amazon Resource Name (ARN) of a cached volume. All of the specified cached volumes must be from the same gateway. Use ListVolumes to get volume ARNs for a gateway.

(string)

Syntax:

"string" "string" ...

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

CachediSCSIVolumes -> (list)

An array of objects where each object contains metadata about one cached volume.

(structure)

Describes an iSCSI cached volume.

VolumeARN -> (string)

The Amazon Resource Name (ARN) of the storage volume.

VolumeId -> (string)

The unique identifier of the volume, e.g., vol-AE4B946D.

VolumeType -> (string)

One of the VolumeType enumeration values that describes the type of the volume.

VolumeStatus -> (string)

One of the VolumeStatus values that indicates the state of the storage volume.

VolumeAttachmentStatus -> (string)

A value that indicates whether a storage volume is attached to or detached from a gateway. For more information, see Moving your volumes to a different gateway .

VolumeSizeInBytes -> (long)

The size, in bytes, of the volume capacity.

VolumeProgress -> (double)

Represents the percentage complete if the volume is restoring or bootstrapping that represents the percent of data transferred. This field does not appear in the response if the cached volume is not restoring or bootstrapping.

SourceSnapshotId -> (string)

If the cached volume was created from a snapshot, this field contains the snapshot ID used, e.g., snap-78e22663. Otherwise, this field is not included.

VolumeiSCSIAttributes -> (structure)

An VolumeiSCSIAttributes object that represents a collection of iSCSI attributes for one stored volume.

TargetARN -> (string)

The Amazon Resource Name (ARN) of the volume target.

NetworkInterfaceId -> (string)

The network interface identifier.

NetworkInterfacePort -> (integer)

The port used to communicate with iSCSI targets.

LunNumber -> (integer)

The logical disk number.

ChapEnabled -> (boolean)

Indicates whether mutual CHAP is enabled for the iSCSI target.

CreatedDate -> (timestamp)

The date the volume was created. Volumes created prior to March 28, 2017 don’t have this timestamp.

VolumeUsedInBytes -> (long)

The size of the data stored on the volume in bytes. This value is calculated based on the number of blocks that are touched, instead of the actual amount of data written. This value can be useful for sequential write patterns but less accurate for random write patterns. VolumeUsedInBytes is different from the compressed size of the volume, which is the value that is used to calculate your bill.

Note

This value is not available for volumes created prior to May 13, 2015, until you store data on the volume.

If you use a delete tool that overwrites the data on your volume with random data, your usage will not be reduced. This is because the random data is not compressible. If you want to reduce the amount of billed storage on your volume, we recommend overwriting your files with zeros to compress the data to a negligible amount of actual storage.

KMSKey -> (string)

The Amazon Resource Name (ARN) of a symmetric customer master key (CMK) used for Amazon S3 server-side encryption. Storage Gateway does not support asymmetric CMKs. This value can only be set when KMSEncrypted is true . Optional.

TargetName -> (string)

The name of the iSCSI target used by an initiator to connect to a volume and used as a suffix for the target ARN. For example, specifying TargetName as myvolume results in the target ARN of arn:aws:storagegateway:us-east-2:111122223333:gateway/sgw-12A3456B/target/iqn.1997-05.com.amazon:myvolume . The target name must be unique across all volumes on a gateway.

If you don’t specify a value, Storage Gateway uses the value that was previously used for this volume as the new target name.
