Configuring a mirrorclone-snapshot
The Mirrorclone-Snapshot tab in the Settings window enables you to select a disk group and modify
the mirrorclone-snapshot properties.
You can:
• Select a redundancy level from the Select redundancy type for Mirrorclone-Snapshot vdisk list:
• Default – Same as source
• Vraid0 – No redundancy
• Vraid1 – Mirroring
• Vraid5 – Data plus parity
• Vraid6 – Double parity disks
• Select the snapshot type:
• Fully Allocated – Space for the copy is reserved in advance and filled when data is copied to
the snapshot.
• Demand Allocated – Space for the copy is created only as it is needed when data is copied
to the copy volume.
• Select the state of the mirrorclone after a snapshot:
• Sync – Synchronized state; I/Os are continuously updated on the mirrored pairs.
• Fractured – I/Os are not continuously updated on the mirrored pairs.
