== How to Run Inventory ==
To run inventory preform the following: 

 From repository1::
 1. Goto the tfptboot directory and make a symbolic link for the appropriate domain
    {{{
root@repository1:~# cd /tftpboot/pxelinux.cfg/
root@repository1:/tftpboot/pxelinux.cfg# ln -s inventory-nb-grid 0A0A
    }}}

    || '''HEX''' || '''Domain'''  || 
    || 0A0A      || Grid          ||
    || 0A0B      || SB1           ||
    || 0A0C      || SB2           ||
    || 0A0D      || SB3           ||
    || 0A0E      || SB4           ||
    || 0A0F      || SB5           ||
    || 0A10      || SB6           ||
    || 0A11      || SB7           ||
    || 0A12      || SB8           ||
    || 0A13      || SB9           ||
    || 0A28      || Outdoor       ||

 2. goto the /export/nfsroot/etc/resolvconf/resolv.conf.d and make a symbolic link to head for the proper domain e.g. for grid:
    {{{
cd /export/nfsroot/etc/resolvconf/resolv.conf.d
root@repository1:/export/nfsroot/etc/resolvconf/resolv.conf.d# ln -s head.grid head
    }}}
    for sb1:
    {{{
cd /export/nfsroot/etc/resolvconf/resolv.conf.d
root@repository1:/export/nfsroot/etc/resolvconf/resolv.conf.d# ln -s head.sb1 head
    }}}
 3. '''If you are inventorying grid:'''
As root run the run_inventory script:
    {{{
root@console.grid:~# cd /root/inventory/
root@console.grid:/root/inventory# ./run_inventory.rb
    }}}
    Starting Output will look like:
    {{{
root@console.grid:/root/inventory# ./run_inventory.rb 
/usr/lib/ruby/vendor_ruby/restclient/response.rb:11: warning: method redefined; discarding old body

    }}}
    This script will take 45 minutes to run.
'''If you are inventorying a sandbox:'''
   1. Turn on (or restart) all nodes, so the boot into the inventory pxe-image
   1. Check the inventory page for the sandbox you are inventorying, e.g. for sandbox9:
   {{{
http://internal1.orbit-lab.org:5054/inventory/attribute_list?set=node*.sb9.orbit-lab.org*
   }}}
   1. Wait until all the nodes check in, then proceed to next step.   
 From repository1::
 4. '''Break the link''' if this is not done the next person to use the grid will have a bad time. 
    {{{
rm 0A0A
    }}}
 5. Update the inventory service "domain topology" cache (which nodes belong to what testbeds) by visiting the following URL:
   {{{
http://internal1.orbit-lab.org:5054/inventory/update_cache
   }}}
 From internal1::
 6. run the ruby scripts:
    {{{
root@internal1:~# cd /usr/share/omf-aggmgr-5.4/omf-aggmgr/ogs_inventory/
root@internal1:/usr/share/omf-aggmgr-5.4/omf-aggmgr/ogs_inventory# ruby mktopo_cpu.rb
root@internal1:/usr/share/omf-aggmgr-5.4/omf-aggmgr/ogs_inventory# ruby mktopo_dev.rb
root@internal1:/usr/share/omf-aggmgr-5.4/omf-aggmgr/ogs_inventory# ruby mktopo_disk.rb
    }}}
    '''Note''': each ruby script takes some time to preform all the actions, and the omf-agg-manager restarts every even hour on the 11th minute. If the ruby process is running at that time it will fail.
