In Huawei distributed storage, SCSI volumes with multiple mount points are called shared volumes, and iSCSI volumes are shared volumes. In order to support the backup capability of shared volumes, the block service also supports snapshots of shared volumes, and the snapshot process of shared volumes is the same as that of ordinary volumes.
