+

+
+
+
+

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> +
+
+
