#Invalid arguments full#
Subsequent full backups will fail the second copy when trying to retrieve previous backup include data.
If the user clicks on the order again, he should be prompted with a. If the policy is sent to a SLP with multiple backup destinations, NetBackup will write two accelerated copies at the same time to different storage units. A user cannot bid on a order more than once. This is enforced in the policy editing screen of the NetBackup GUI, and the interface will not permit selection of both Accelerator and multiple copies (in the schedule dialog). Invalid Arguments Here are three common types of invalid argument: Affirming the Consequent Consider this argument: (1) If I’m sweating, I must be working out hard enough. = CauseĪccelerator does not support writing the same image to two storage units at the same time (inline copy). Think back to the diagram that we drew to illustrate AB: if something isn’t in B, then it can’t be in A either. The bptm log will show storage server errors 20600053, as shown below from a bptm log at verbose level 5: The policy editing screen will explicitly disallow multiple copies for this reason, by greying out the 'multiple copies' section: 10:01:34 PM - Error bptm(pid=6436) INF - media write error (84), cannot continue with copy 2 10:01:34 PM - Error bptm(pid=6436) cannot write image to disk, Invalid argument
10:01:30 PM - Critical bptm(pid=6436) image write failed: error 2060001: one or more invalid arguments 10:01:30 PM - Critical bptm(pid=6436) include image failed Note, that a valid argument is satisfiable, invalid arguments may be satisfiable unless they are not satisfiable (just think about it).When a accelerator backup is initiated via a Storage Lifecycle Policy (SLP) with a second copy configured, the second copy will fail with status 84 (media write error): Invalid implies that the argument is not true for all instancesĪn argument is satisfiable if at keast one instance is true, and is not satisfiable if all instances end in false. Valid implies that the argument must be true for all instances (i.e., all rows end in true) In this context, when we consider truth tables and the conclusion is connected with the premise(s) using an implies (i.e., ), the following statements can be made: Pn Q is a valid argument when it is a tautology (where the P's are propositions). Notice that it is possible to have multiple critical rows, and remember that for an argument to be valid, all critical rows must have true conclusions!Ī valid argument for a propositional well formed formula (wff) say P1 P2 P2. While rows 3, 4 and 5 indicate valid (true) premises, the 4th row reveals a false conclusion (indicated by dark blue) therefore, the above argument form is invalid. An invalid argument form can likewise be demonstrated by truth tables. The critical row is highlighted in blue.Ģ.
P (q r) and ~p are the premises, while q r is the conclusion. The validity of the following argument is confirmed by the critical rows of the truth table as shown below.
