Deleting data


Summary

Eventually, a node backed up to TSM is retired.  Some time after that, we come to the decision that the machine's data should be discarded.  Herein find instructions to accomplish that process.


I see in my report a device:

 server 'ext', OLD-CAP3.JOU.UFL.EDU
   tolerance     age(days)     filespace                              
   1             1357.4        /opt                                   
   1             1357.4        /usr                                   
   1             1357.4        /space                                 
   1             1357.4        /home                                  
   1             1357.4        /                                      
   1             1357.4        /var                                   
   1             1357.4        /boot                                  

I think this entire machine can go away.  I should check first, to make sure there are no other filespaces, which are up to date, among these.

tsm: EXT>q filespace OLD-CAP3.JOU.UFL.EDU *

Having satisfied myself that I want to completely remove the machine,  I need to 'delete' the file spaces.  I log into the TSM admin command line (dsmadmc), and
run the command:

tsm: EXT> del filespace OLD-CAP3.JOU.UFL.EDU * 


This deletes -ALL- of the filespaces associated with that machine.

You'll be able to see the deletion effort procedding by watching the
extant processes.

tsm: EXT>q proc
 Process     Process Description      Status                                           
  Number                             
--------     --------------------     -------------------------------------------------
   1,523     DELETE FILESPACE         Deleting file space * (backup/archive data) for 
                                       node OLD-CAP3.JOU.UFL.EDU: 32026 objects       
                                      deleted.                                       

 



Eventually, that process will be gone.  You can then 'remove' the node:

tsm: EXT>rem node old-cap3.jou.ufl.edu


If you've got a machine for which you only want to delete _some_ data,
like my workstation here...

 server 'int', CORNPONE.OSG.UFL.EDU
   tolerance     age(days)     filespace                               
   1             15033.5       /media/3165-3666                        


you can identify the affected filespace with 'q filespace'.


tsm: INT>q filespace cornpone.osg.ufl.edu

Node Name       Filespace   FSID Platform Filespace Is Files-    Capacity   Pct
                Name                      Type        pace           (MB)  Util
                                                    Unicode?              
--------------- ----------- ---- -------- --------- --------- ----------- -----
CORNPONE.OSG.U- /              1 Linux86  EXT4         No       228,965.9  29.2
 FL.EDU                                                                       
CORNPONE.OSG.U- /media/316-    2 Linux86  VFAT         No         7,572.0  17.3
 FL.EDU          5-3666                                                       



So that odd filespace (in fact it attempted to backup my phone) is
filespace ID 2.  So I can:

tsm: INT> del filespace cornpone.osg.ufl.edu 2 namet=fsid

This says I'm deleting filespace '2', and identifying the filespace by
FSID instead of name.  This is frequently more convenient, especially
with UNC-based path names.
