Administering AFM to cloud object storage

Managing AFM to cloud object storage keys
Use the mmafmcoskeys command for the keys management in the AFM to cloud object storage. Each object has data, metadata, and keys. The object key (or key name) uniquely identifies the object in a bucket.
Creating AFM to cloud object storage relation in different modes
You can set an IBM Storage Scale cluster to create AFM to cloud object storage filesets to connect to cloud object services such as Amazon S3, Microsoft Azure Blob, and IBM Cloud® Object Storage. To set an AFM to cloud object storage relation, you can use read-only (RO), single-writer (SW), local-update (LU), and independent-writer (IW) modes in the AFM to cloud object storage.
Evicting files or objects data
Complete the following steps to evict data from files or objects:
Evicting files or objects metadata
Complete the following steps to evict metadata from files or objects:
Evicting data or objects by using the manual updates mode of the AFM to cloud object storage
The replication of the AFM to cloud object storage file system by using manual updates mode does not support automatic eviction, instead data or objects can be evicted by using mmafmcosctl evict command.
Mapping a directory to a cloud object storage bucket
You can map a directory to a bucket on a cloud object storage. This directory can be created under the fileset junction path.
Uploading objects
You can upload objects that are in the LU-mode.
Downloading objects
Download of an object is important when the AFM to cloud object storage relation is created in the ObjectOnly mode. With the ObjectOnly mode, the fileset does not automatically synchronize with a cloud object storage. This behavior is the default behavior of operation.
Converting IBM Storage Scale independent fileset to manual update mode
You can convert the existing IBM Storage Scale independent fileset to manual update (MU) mode.
Uploading and downloading files from MU mode fileset
The files can be uploaded and downloaded from cloud object storage by using AFM Manual Update (MU) mode.
AFM to COS upload and download statistics
You can get an ongoing statistics report when AFM to cloud object storage upload and download task is in progress.
Synchronization of AFM to cloud object storage data to the bucket by using prefix
Prefixes can be used to organize AFM to cloud object storage fileset data inside a bucket. You can upload and download fileset data to the prefix inside the target bucket by creating an AFM to cloud object storage fileset by using user-defined prefix.
Migration of a transparent cloud tiering-enabled IBM Storage Scale fileset or file system to an AFM to cloud object storage fileset in the manual update mode
AFM can perform inline migration of a transparent cloud tiering (TCT) enabled IBM Storage Scale-independent fileset or file system by promoting it to an AFM to cloud object storage fileset in the manual update (MU) mode. During the migration, file data is not recalled from a cloud tier to a cache fileset. AFM replaces TCT attributes from all files to AFM-specific attributes after the conversion.
Converting an AFM to cloud object storage fileset supporting Azure Blob storage by using a MinIO gateway to native Azure Blob storage
In earlier releases of IBM Storage Scale 5.1.9, the AFM to cloud object storage for Azure Blob is executed by using a MinIO gateway. From IBM Storage Scale 5.1.9, an AFM to cloud object storage fileset can connect to Azure Blob natively without any intermediate gateway or application
