CAUTION: If you want to mount the volume of a snapshot, clone, or replica using the Group Manager GUI, mount it to a standalone node or a cluster node in a different cluster. Do not mount the snapshot, clone, or replica of a clustered disk to a node in the same cluster because it has the same disk s...

Volumes Cloning a volume creates a new volume with a new name and iSCSI target, having the same size, contents, and Thin Provisioning setting as the original volume. The new volume is located in the same pool as the original volume and is available immediately. Cloning a volume does not affect the o...

Replication Replication enables you to copy volume data across groups, physically located in the same building or separated by some distance. Replication protects the data from failures ranging from destruction of a volume to a complete site disaster, with no impact on data availability or performan...

Volume Collections NOTE: Do not use the Group Manager GUI to mount the clone of a clustered disk to a node in the same cluster. A volume collection consists of one or more volumes from any pool and simplifies the creation of snapshots and replicas. Volume collections are useful when you have multipl...
