Manage storage groups by configuring the storage to make it attachable or non-attachable. You also have the option of marking a storage read-only so that App Volumes Manager can skip writing to that storage when updating a package or an AppStack.

The list of storage locations and their status is displayed on the Managed Storage Locations page.

When you configure a storage as not attachable, the App Volumes Manager ignores the storage while mounting volumes.

For example, if you have set up two vCenter Server instances. Each instance can have a local storage and shared storage capability. You can configure the slower-performing storage as Set Not Attachable. A storage thus configured as not attachable is ignored by the manager while mounting volumes and the storage can be used solely for replication of packages and AppStacks.

If the metadata of a package or an AppStack is updated and the package or AppStack is replicated from a read-only storage, App Volumes Manager skips writing the updates to the read-only storage, but the package or AppStack gets replicated. The replicated package or AppStack does not have the updated metadata. You have the option of removing the read-only marker on the storage.

Note: AppStacks and Writable Volumes (2.x) can be created only by using App Volumes Agent 2.x and uploading the appropriate templates. Any information related to these volumes can be viewed only when the VOLUMES (2.X) tab is visible in the App Volumes Manager UI. If you have installed the latest version of App Volumes Manager and want to explore App Volumes 2.x, see Perform App Volumes 2.x Management Tasks.
