create task Description Creates a task that can be scheduled. You can create a task to enable or disable drive spin down; to take a snapshot of a standard or master volume; to reset a snapshot; to copy a standard, master, or snapshot volume to a new standard volume; or to replicate a replication set's primary volume to a remote system. The first time a snapshot or volume copy is created of a standard volume, the volume is converted to a master volume and a snap pool is created in the volume's vdisk. The snap pool's size is either 20% of the volume size or 5.37 GB, whichever is larger. Before creating or scheduling snapshots or copies, verify that the vdisk has enough free space to contain the snap pool. The recommended minimum size for a snap pool is 50 GB. CAUTION: Before scheduling a ResetSnapshot task, consider that if the snapshot is mounted/presented/mapped to a host, the snapshot must be unmounted/unpresented/unmapped before the reset is performed; leaving it mounted/presented/mapped can cause data corruption. You should create a scheduled job on the host to unmount/unpresent/unmap the snapshot prior to resetting it.
