Synopsis

Calls the AWS Storage Gateway RefreshCache API operation.

Syntax

Invoke-SGCacheRefresh
-FileShareARN <String>
-FolderList <String[]>
-Recursive <Boolean>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Refreshes the cache for the specified file share. This operation finds objects in the Amazon S3 bucket that were added, removed or replaced since the gateway last listed the bucket's contents and cached the results. This operation is only supported in the file gateway type. You can subscribe to be notified through an Amazon CloudWatch event when your RefreshCache operation completes. For more information, see Getting Notified About File Operations. When this API is called, it only initiates the refresh operation. When the API call completes and returns a success code, it doesn't necessarily mean that the file refresh has completed. You should use the refresh-complete notification to determine that the operation has completed before you check for new files on the gateway file share. You can subscribe to be notified through an CloudWatch event when your RefreshCache operation completes. Throttle limit: This API is asynchronous so the gateway will accept no more than two refreshes at any time. We recommend using the refresh-complete CloudWatch event notification before issuing additional requests. For more information, see Getting Notified About File Operations. If you invoke the RefreshCache API when two requests are already being processed, any new request will cause an InvalidGatewayRequestException error because too many requests were sent to the server. For more information, see "https://docs.aws.amazon.com/storagegateway/latest/userguide/monitoring-file-gateway.html#get-notification".

Parameters

-FileShareARN <String>
The Amazon Resource Name (ARN) of the file share you want to refresh.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-FolderList <String[]>
A comma-separated list of the paths of folders to refresh in the cache. The default is ["/"]. The default refreshes objects and folders at the root of the Amazon S3 bucket. If Recursive is set to "true", the entire S3 bucket that the file share has access to is refreshed.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the FileShareARN parameter. The -PassThru parameter is deprecated, use -Select '^FileShareARN' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Recursive <Boolean>
A value that specifies whether to recursively refresh folders in the cache. The refresh includes folders that were in the cache the last time the gateway listed the folder's contents. If this value set to "true", each folder that is listed in FolderList is recursively updated. Otherwise, subfolders listed in FolderList are not refreshed. Only objects that are in folders listed directly under FolderList are found and used for the update. The default is "true".
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.StorageGateway.Model.RefreshCacheResponse). Specifying the name of a property of type Amazon.StorageGateway.Model.RefreshCacheResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesSK, SecretAccessKey
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesST

Outputs

This cmdlet returns an Amazon.StorageGateway.Model.RefreshCacheResponse object containing multiple properties. The object can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
