Updating file systems

This topic explains which properties of an existing file system that you can update, and provides procedures to do so using the console and CLI.

You can update the following FSx for ONTAP file system properties using the Amazon FSx console, the AWS CLI, and the Amazon FSx API:

• Automatic daily backups. Turns automatic daily backups on or off, modifies the backup window and the backup retention period. For more information, see Automatic daily backups.

• Weekly maintenance window. Sets the day of the week and time that Amazon FSx performs file system maintenance and updates. For more information, see Optimizing performance with Amazon FSx maintenance windows.

• File system administrative password. Changes the password for the file system's fsxadmin user. You can use the fsxadmin user to administer your file system using the ONTAP CLI and REST API. For more information about the fsxadmin user, see Managing file systems with the ONTAP CLI.

• Amazon VPC route tables. With Multi-AZ FSx for ONTAP file systems, the endpoints you use to access data over NFS or SMB and the management endpoints to access the ONTAP CLI, API, and BlueXP use floating IP addresses in the Amazon VPC route tables that you associate with your file system. You can associate new route tables that you create with your existing Multi-AZ file systems—allowing you to configure which clients can access your data even as your network evolves. You can also disassociate (remove) existing route tables from your file system.

  Note

  Amazon FSx manages VPC route tables for Multi-AZ file systems using tag-based authentication. These route tables are tagged with Key: AmazonFSx; Value: ManagedByAmazonFSx. When creating or updating FSx for ONTAP Multi-AZ file systems using AWS CloudFormation we recommend that you add the Key: AmazonFSx; Value: ManagedByAmazonFSx tag manually.

To update a file system (console)

The following procedures provide you with instructions on how to make updates to an existing FSx for ONTAP file system using the AWS Management Console.

To update automatic daily backups

1. Open the Amazon FSx console at https://console.aws.amazon.com/fsx/.

2. To display the file system details page, in the left navigation pane, choose File systems, and then choose the FSx for ONTAP file system that you want to update.

3. Choose the Backups tab in the second panel on the page.

4. Choose Update.

5. Modify the automatic daily backup settings for this file system.

6. Choose Save to save your changes.

To update the weekly maintenance window

1. Open the Amazon FSx console at https://console.aws.amazon.com/fsx/.

2. To display the file system details page, in the left navigation pane, choose File systems, and then choose the FSx for ONTAP file system that you want to update.

3. Choose the Administration tab in the second panel on the page.

4. In the Maintenance pane, choose Update.

5. Modify when the weekly maintenance window occurs for this file system.

6. Choose Save to save your changes.

To change the file system administrative password

1. Open the Amazon FSx console at https://console.aws.amazon.com/fsx/.

2. To display the file system details page, in the left navigation pane, choose File systems, and then choose the FSx for ONTAP file system that you want to update.

3. Choose the Administration tab.

4. In the ONTAP administration pane, choose Update under ONTAP administrator password.

7. Choose Update credentials to save your change.

   Note

   If you receive an error stating that the new password does not meet the password requirements, you can use the security login role config show ONTAP CLI command to view the password requirement settings on the file system. For more information, including instructions on how to change password setting, see Updating the fsxadmin account password fails.

To update VPC route tables on Multi-AZ file systems

1. Open the Amazon FSx console at https://console.aws.amazon.com/fsx/.

2. To display the file system details page, in the left navigation pane, choose File systems, and then choose the FSx for ONTAP file system that you want to update.

3. For Actions, choose Manage route tables. This option is only available for Multi-AZ file systems.

4. In the Manage route tables dialog box. do one of the following:

   • To associate a new VPC route table, select a route table from the Associate new route tables dropdown list, and then choose Associate.

   • To disassociate an existing VPC route table, select a route table from the Current route tables pane, and then choose Disassociate.

5. Choose Close.

To update a file system (CLI)

The following procedure illustrates how to make updates to an existing FSx for ONTAP file system using the AWS CLI.

1. To update the configuration of an FSx for ONTAP file system, use the update-file-system CLI command (or the equivalent UpdateFileSystem API operation), as shown in the following example.

   aws fsx update-file-system \
       --file-system-id fs-0123456789abcdef0 \
       --ontap-configuration AutomaticBackupRetentionDays=30,DailyAutomaticBackupStartTime=01:00, \
         WeeklyMaintenanceStartTime=1:01:30,AddRouteTableIds=rtb-0123abcd, \
         FsxAdminPassword=new-fsx-admin-password

2. To disable automatic daily backups, set the AutomaticBackupRetentionDays property to 0.

   aws fsx update-file-system \
       --file-system-id fs-0123456789abcdef0 \
       --ontap-configuration AutomaticBackupRetentionDays=0
