Gabe,

For your first question, if I'm reading it right, any policy set to 0 has 
the lowest priority. When creating a policy, the default priority is 0 
unless specified otherwise. I think that the two descriptions are saying 
the same thing differently. Symantec has alluded in the past to wanting to 
shore up these differences in all the different documentation.

For the second question, I have no idea.

Subject
[Veritas-bu] Making use of 6.5.2+ default priorities in the presence of 
pre-existing policy priority settings






In my environments, there are already some policy priority settings in 
place. For the most part, I would like to clear those and make use of 
default priorities... but I'm hazy on what "clear" means.

The bpplinfo man page says:

      -priority priority

                The priority of this policy in relation to other policies.
                Priority is greater than or equal to 0. This value
                determines the order in which policies are run. The higher
                the value, the earlier the policy is run. The default is 
0,
                which is the lowest priority.

And the 6.5.2 documentation update says (on page 369):

  bpplinfo  Use the -priority option to specify a new priority for the 
backup
            job that overrides the default job priority.


Has anyone yet determined empirically whether a priority setting of 0 
(which is the default if no priority is specified with bppolicynew) on the 
policy is a special case that means "use the default" rather than 
"override the default", even if the priority was previously set to a 
higher number?


The 6.5.2 documentation update also mysteriously refers to a "first" and 
"second" priority in the "Understanding the Job Priority setting" section 
(on page 358):

  The NetBackup Resource Broker (NBRB) maintains resource requests for 
jobs in
  a queue. NBRB evaluates the requests sequentially and sorts them based 
on the
  following criteria:
  * The request's first priority.
  * The request's second priority.
  * The birth time (when the Resource Broker receives the request).
  The first priority is weighted more heavily than the second priority, 
and the
  second priority is weighted more heavily than the birth time.


Has anyone sorted out what "first" and "second" mean here?
