Prior to breaking a SnapMirror DP relationship, which statement is true about mounting the destination volume?

The correct answer is C. It can be mounted in the namespace of the destination Vserver. Before breaking a SnapMirror DP relationship, the destination volume is in a read-only restricted state but can be mounted within the destination Vserver's namespace.

Prior to breaking a SnapMirror DP relationship, which statement is true about mounting the destination volume?

Options

  • BIt cannot be mounted until after the SnapMirror break is performed.
  • CIt can be mounted in the namespace of the destination Vserver.
  • DIt can be mounted only in the same namespace as the source volume.

Why each option

Before breaking a SnapMirror DP relationship, the destination volume is in a read-only restricted state but can be mounted within the destination Vserver's namespace.

AIt can be mounted in the namespace of any Vserver in the source- or destination cluster.

The destination volume is scoped to the destination Vserver and cannot be freely mounted in any Vserver namespace across source or destination clusters.

BIt cannot be mounted until after the SnapMirror break is performed.

Mounting is not blocked prior to the break - the destination volume can be mounted in the destination Vserver namespace in a read-only restricted state before any break is performed.

CIt can be mounted in the namespace of the destination Vserver.Correct

In Clustered Data ONTAP, a SnapMirror DP destination volume is restricted (read-only) but is still mountable within the destination Vserver's namespace prior to breaking the relationship. This allows administrators to verify replicated data without disrupting the active SnapMirror relationship. The volume remains read-only and under SnapMirror control until the break command is issued.

DIt can be mounted only in the same namespace as the source volume.

The destination volume resides on the destination cluster and Vserver, not in the same namespace as the source volume, and does not require namespace alignment with the source.
