Here we've this important files:
 
−
* srm22-prod.xml              - This is the file you'll need to edit
 
−
* LinkGroupAuthorization.xsl  - Compiles srm22-prod.xml to generate the LinkGroupAuthorization file, needed in the SRM node (srm.pic.es)
 
−
* poolmanagerconfig.xsl        - Compiles srm22-prod.xml to generate PoolManager.conf file, needed in the PoolManager node (dccore.pic.es)
 
−
* propagarCanvis.sh            - This eases your life compiling files and copying them where they need to be.
 
−
* historic                    - In this directory you'll find old versions of the config files

'''3. Now you've to edit srm22-prod.xml, look for (ie we want to add a pool to lhcb) pgroup-$VO (pgroup-lhcb) and you'll see:'''

<!--PoolGroups LHCb-->

  <poolgroup name="pgroup-lhcb">

      <pool name="dc023_1"/>

      <pool name="dc043_1"/>

Adding a new pool is as easy as making another pool name line with the right pool name.
 
−
 
−
Moving pools between poolgroups is the same, just make sure the pool is empty before moving it, if not you might make a mess.

'''4. Now you've to run propagarCanvis.sh this way:'''
 
−
* First we check what is actually changing:
 
−
<pre>
 
−
[root@dccore01 srm22]# ./propagarCanvis.sh srm22-prod.xml
 
−
diff /tmp/LinkGroupAuthorization.conf.temp /opt/d-cache/etc/LinkGroupAuthorization.conf
 
−
 
−

−
 
−
diff /tmp/PoolManager.conf.temp /opt/d-cache/config/PoolManager.conf
 
−
[root@dccore01 srm22]#
 
−
</pre>
 
−
* If it's OK we have to run ''./propagarCanvis.sh srm22-prod.xml -yes''
 
−
 
−
After adding a pool to a poolgroup, make sure it has all movers to the right value; sometimes it's not a big deal but it's worth to check it (via the admin interface in the ''generic infos queue summary'' or via CLI with the ''info'' command and grepping for ''Mover Queue'').
