Removing a cache device

Depending on your deployment plan, client activity, and overall system performance, you might need to remove a NAS Bridge cache device. In general, if a cache device is not associated with a file system and not planned for a future file system, you should remove it.

Before you begin

The cache device must not be associated with any file systems.

  4. Remove the hard drive (disk) from vSphere.
