     38 1. Display information about available SE resources for VO `vo.lal.in2p3.fr`, using command  [wiki:Tutorial/SystemInfo#LaCommandelcg-infosites lcg-infosites].
    3939   * How many SEs are available for VO vo.lal.in2p3.fr ?
    4040   * Find the same information for VO `dteam`. How many SEs are available for this VO ?
    4141 1. Create a text file and copy it on a SE using command `lcg-cr`, using option `-l` to define the logical name (see above for the logical name format).  On which SE is the file located?  Try to explicitly define the destination SE.
    42  1. Check that the file(s) is present in the catalog and list its replicas, using command `lcg-lr`. This should return SURL for all the replicas (a SURL starts with prefix `srm:`).

    48  1. Suppress one of the replica using command `lcg-del` and check the result with `lcg-lr`.
    49  1. Suppress the other replica using command `lcg-del` and check the result with `lcg-lr`.
     48 1. Erase one of the replicas using command `lcg-del` and check the result with `lcg-lr`.
     49 1. Erase the other replica using command `lcg-del` and check the result with `lcg-lr`.
    5050 1. Recreate a file with 2 replicas and try to suppress all the replicas at once. Try to do a `lcg-lr` and a `lcg-ls`.
