VTL - occupation
With reference to the attachment that report the slide of actual occupation of my vtl, can you have a detailed report of how and from wath is occupied with script tsm ?

I have still a question :
If I sum the totals occupied by each stg I return a value that does not correspond to what is indicated in the attached graph, and precisely from the query I have a total of :
STGPOOL_NAME GB
VVR_DBVPM 10661.44
VVR_DEVQUA 46713.23
VVR_INCR 2439.66
VVR_PROD 41533.89
VVR_PRODMON 18616.79
VVR_PRODYEA 1428.94
VVR_TOC 15.05
-------------------------- ---------- ---------
GRAN TOTAL 121409.00
while from the attached graph I have backup for TiB 170.8= TB 183 , there is a difference about 50TB, why this difference?

Hi,
this is not that simple as adding up numbers ...
VTL is declaring 170 TB of "Nominal" type, e.g. what it is declared by operating systems at source (VTL is reading the value, not measuring it)
TSM is declaring what it has measured on its stgpools, AFTER its own compression (not the value declared from source).
The only thing I would expect from this analisys is that
TSM declared value <= VTL "Nominal" value
but I believe it is useless to compare those 2 values, which on the contrary are really important when taken each of them into their own realm.
hope this helps

Hi,
I was wondering if I have to apply some cleaning procedure for any backup now outside retention?

No, I don't think there is any cleaning procedure you should do

One last thing if I wanted to check for any backup out of retention I can execute the following command:
expire inventory duration=120
Do you confirm that it only removes backups out retention?
expire inventory duration=120

Hi,
"expire inventory" process removes expired file copies from storage pools and tsm db. Removal is based on policy specifications, which you have set into copygroups associated to management classes to which the files are bound.
q copy
for backup files
and
q copy T=a
for archived files
It is usually scheduled into maintenance script.
Alternatively, it might have been into the server option files:
q opt expinterval

Hi,
I have ;

How maintenance which type of script can I use?
Can I have an example?

Hi,
Expinterval=0 means that the expire inventory process is not scheduled into dsmserv.opt file.
So you should have an administrative script scheduled. You can find it out by issuing first:
q sched T=A
which will inform you on admin scheds.
Into the sched there must be a script which you can read by issuing:
q script <script_name> F=R
into one of the scripts there must be a line: "expire inventory"

The support is fine
you can use the following query:
SELECT node_name, stgpool_name, type, CAST(FLOAT(SUM(logical_mb)
and you may as well filter out only the stgpools you want.
hope this helps
