+DESCRIPTION
+-----------
+The Reservation Acquire command is used to acquire a reservation on
+a namespace, preempt a reservation held on a namespace, and abort a
+reservation held on a namespace.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Override the nsid field. If using the admin character device,
+	this parameter is required.
+
+-c <crkey>::
+--crkey=<crkey>::
+	Current Reservation Key: The field specifies the current
+	reservation key associated with the host. If the IEKEY bit is
+	set to ‘1’ in the command, then the CRKEY check succeeds
+	regardless of the value in this field.
+
+-p <prkey>::
+--prkey=<prkey>::
+	Preempt Reservation Key: If the Reservation Acquire Action is set
+	to 001b (i.e., Preempt) or 010b (i.e., Preempt and Abort), then
+	this field specifies the reservation key to be unregistered from
+	the namespace. For all other Reservation Acquire Action values,
+	this field is reserved.
+
+-t <rtype>::
+--rtyep=<rtype>::
+	Reservation Type: This field specifies the type of reservation
+	to be created.
