What command is used to create a new mirror in a different location for a meta-volume?

• A. meta-volume detach-mirror
• B. meta-volume create
• C. meta-volume move
• D. meta-volume attach-mirror

Answer: (D)

To create a new mirror in a different location for a meta-volume, the command used is to attach a new mirror to the existing meta-volume. This process allows for the expansion of redundancy and availability of the data by introducing a new mirror, which can be placed in a different physical location for protection against local outages or failures. When using the attach-mirror command, the existing meta-volume can effectively incorporate the new mirror, thus enhancing its data protection capabilities and potentially improving read performance by distributing the I/O load across multiple locations. In this context, the detach-mirror command is intended for removing a mirror, the create command is focused on establishing entirely new meta-volumes rather than mirrors, and the move command pertains to relocating existing meta-volumes without the intent of creating a mirror. Each of these commands serves a different purpose and does not specifically address the need to create a new mirror in a different location for a meta-volume.
