Howto Add a NDMP DLE to Zmanda Using the ZMC Console

  • Point your browser to the ZMC console at http://dow.bic.mni.mcgill.ca.
  • Login to the ZMC console as user admin (you will need the user’s credentials to login) and select the isilon backup set
  • There is only one available anyway so it should selected by default.
  • Goal: to add a DLE (Disk Logical Entry) to the Zmanda server config isilon:
  • For example, the NFS share /ifs/data/upet1 on the Isilon cluster.
  • To do that one must specify that the server will access the client with NDMP protocol (Network Data Management Protocol).
  • Go to the tab Backup.
    • Minor detail: the snapshot below was taken after adding the upet1 DLE.
    • Just pretend it’s not there!
  • In the Add top panel, select NDMP under the File Systems… menu.
  • In the new window, enter the following info:
    • At the left: 
    Filer Host Name:  nfs.isi-node.bic.mni.mcgill.ca
    Volume Name:      /ifs
    Directory:        /data/upet1
    Vendor:           EMC Celerra
  • At the right: 
    Username:         ndmp
    Password:         ******
    Auth Type:        MD5
  • Notes: the password entry is mandatory as the Amanda server access the Isilon cluster (through NDMP) as the user ndmp.
  • This user has been enabled on the Isilon cluster and requires a password.
  • Without it, any NDMP access will be denied.
  • MD5 authentication makes sure the password in not sent in clear text and is not saved unprotected in the Amanda server’s config files.
  • Obviously, this is not military-grade encryption :)
  • Click the Add button the lower right corner ot the top panel.
  • You should see the new DLE appears in the display list of the backup set.
  • Note the hostname for the new DLE is 127.0.0.1.
  • This must be changed to dow172.
  • We will do that later.
    • If you wish so, you can modify the DLE’s hostname by manually editing the file /etc/amanda/isilon/disklist.conf on the Amanda server and changing 127.0.0.1 to dow172.
    • Once done, verify the state of the amanda server and clients by typing on the server sudo -u amandabackup amcheck isilon.
    • Fix any errors or warning that show up.
    • Warnings about the fact that index files will be created for the new DLE can be safely ignored.
    • If all is good, your job is done!
  • If you want to absolutely use the ZMC, continue here:
  • First, at the bottom, click the button Check Hosts and make sure that all DLEs return OK (green tick).
  • Go to tab Admin → Advanced
  • In the box, enter the disklist path, /etc/amanda/isilon/disklist.conf
  • Click button Apply
  • Scroll/Slide to the bottom.
  • Change 127.0.0.1 to dow172
  • Click the button Save Changes
  • Return to the Backup tab and check that the change has been applied correctly.
  • If you prefer, you can also simply logout of the ZMC and manually modify the ascii file /etc/amanda/isilon/disklist.conf
  • Once done validate the Amanda config with sudo -u amandabackup amcheck isilon. Fix any errors if they show up.
  • Congratulations! You now know how to add a NDMP DLE client to Zmanda using the ZMC console. What an amazing feat!
