nvme resv-acquire <device>
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.

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.

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.
