Re: [ADSM-L] AW: [ADSM-L] Export / import nodes with shared library

Otto,
   After you export using the server to server method,  verify that all data 
has been successfully imported to the target TSM server.  Then delete the node 
and all of it's data on the source TSM server.  The volumes holding the deleted 
data will have free space.  The volumes can then be reclaimed through normal 
reclamation or "move data" commands.  Nothing needs to be performed on the TSM 
Library manager.  For a short period of time you will need two times the number 
of tapes because the data is fully duplicated on both the source and target TSM 
servers.

Subject: [ADSM-L] AW: [ADSM-L] Export / import nodes with shared library

Hi again,

Thank you Neil !

- Sorry, but 'UPD LIBV ... OWN=' do not solve the problem ...
  ---> ANR8969E The owner of volume XXXXXX can not be updated to owner TSM1.

- we also use 'EXPORT NODE ... TOSERVER=...'  and it works great.
But it is not very useful to transfer nodedata (hundrets of TB) over ethernet 
because there is no idea how to get the export volumes to scratch state after 
importing on another server in a shared library environment ...

   -> After importing the ownership changes to the importing server
   -> volumes should get back to SCRATCH after 'DEL VOLHIST T=EXP' on the 
exporting server
      (the volumes are deleted from volhist but remain PRIVATE because owner is 
another server)
   -> after that the only way to put them to SCRATCH is 'AUDIT LIBRARY'
      (otherwise the volumes stay PRIVATE forever)

Any other idea(s) ?

Thank you !
Otto

Otto,
- You should be able to just update the libvol owner on the library manager to 
the new server.
- You may also consider using server-server export which transfers data through 
the ethernet from the source to target server.  This process allows for 
concurrent export/import and reduces the chance of mixing up the sequence of 
export tape volumes. To do this you need to set up server-server communications 
betweeen the source and target servers.
See the help page for export node "EXPORT NODE -- Directly to Another Server" 
for the export syntax.

Subject: [ADSM-L] Export / import nodes with shared library

Hi TSM'ers,

We splitted our TSM Server up to five instances (four library clients, one 
library manager, 3494)

To move the nodes to new instances we export/import them on tape

(TSM0 is library manager, TSM1-TSM4 are library clients)

(1) on instance TSM1: Export node to volume(s)
                      volhist entries are made
                      owner ist TSM1

(2) on instance TSM2: import node from those volumes
                        now owner is TSM2
                        there were no entries made into volhist

(3) after succesful import on instance TSM1: del volhist type=export ...
                                               entries in volhist of
TSM1 are removed


But we got an error on TSM0 (Library manager):
ANR9999D smlshare.c(4724): ThreadId <21> Invalid owner(TSM1) attempting to 
delete volume J20010.
....

Is this the normal behavior ?

Is the only way to get the volumes back to scratch an AUDIT LIBRARY on the 
library clients ?

Is this the recommended way to do that ?

Where is the recommended way documented ?

TIA !

Otto
