Re: AW: sql select to count volumes per stgpool by node

Try replacing  count(*) as "Count" with  count(distinct volume_name) as
"Count"

The problem is that a volser can appear multiple times in volumeusage
for a given node/storagepool combination.

Andy,

I do not see an error in your SQL statement, 
but the results are much too good to be correct,
new volumes must be created on the fly during the SQL run:
e.G.
  AOHEXCHANGE00          TPBACSAFE                       81
While I have only 29 tapes in TPBACSAFE ;-)

Juraj

Maybe this?

select node_name as "Node_Name",
       stgpool_name as "StgPool_name",
       count(*) as "Count"
   from volumeusage
   group by stgpool_name, node_name
   order by node_name, stgpool_name

node



What is the syntax of the select statement to show the number of
distinct
volumes used by each stgpool for each node.  The desired output would
be
something like:

Node_Name   StgPool_Name  Count
---------   ------------  ------
yakima      backupcopy         5
yakima      backuptape         3
yakima      arccopy            7
yakima      arctape            6
olympia     backupcopy        23
olympia     backuptape        15
