 Description   

this would looks like the following:

[root@tmp ~]# lctl dl
  0 UP osd-ldiskfs lustre-MDT0000-osd lustre-MDT0000-osd_UUID 8
  1 UP mgs MGS MGS 4
  2 UP mgc MGC192.168.124.114@tcp 2dfbc162-b641-44a0-bfe5-a37d69afd6bd 4
  3 UP mds MDS MDS_uuid 2
  4 UP lod lustre-MDT0000-mdtlov lustre-MDT0000-mdtlov_UUID 3
...
 15 UP mdc lustre-MDT0000-mdc-ffffa3980e797000 c927a465-8ca1-4c82-8725-4107f90d7c98 4

 17 UP osp lustre-OST0000-osc-MDT0000 lustre-MDT0000-mdtlov_UUID 4

notice skipped line 16.
this in turn leads to different testing issues when a test can't find specific device.
