Verify the presence andintegrity of the multicast tree, as shown in Example 4-20.Example 4-20 Verifying the multicast tree# cat /var/opt/isnm/cnm/log/mctree.out********************************************************Multicast tree starts with root********************************************************Root: FR006-CG07-SN004-DR0-HB31: FR006-CG07-SN004-DR0-HB3-1-->FR006-CG07-SN004-DR0-HB0-12: FR006-CG07-SN004-DR0-HB0-2-->FR006-CG07-SN004-DR0-HB5-13: FR006-CG07-SN004-DR0-HB5-2-->FR006-CG07-SN004-DR0-HB2-43: FR006-CG07-SN004-DR0-HB5-3-->FR006-CG07-SN004-DR0-HB4-62: FR006-CG07-SN004-DR0-HB0-3-->FR006-CG07-SN004-DR0-HB1-33: FR006-CG07-SN004-DR0-HB1-2-->FR006-CG07-SN004-DR0-HB6-43: FR006-CG07-SN004-DR0-HB1-7-->FR006-CG07-SN004-DR0-HB7-72: FR006-CG07-SN004-DR0-HB0-42-->FR006-CG11-SN005-DR0-HB0-433: FR006-CG11-SN005-DR0-HB0-1-->FR006-CG11-SN005-DR0-HB3-13: FR006-CG11-SN005-DR0-HB0-2-->FR006-CG11-SN005-DR0-HB5-13: FR006-CG11-SN005-DR0-HB0-3-->FR006-CG11-SN005-DR0-HB1-33: FR006-CG11-SN005-DR0-HB0-4-->FR006-CG11-SN005-DR0-HB4-13: FR006-CG11-SN005-DR0-HB0-5-->FR006-CG11-SN005-DR0-HB2-23: FR006-CG11-SN005-DR0-HB0-6-->FR006-CG11-SN005-DR0-HB7-33: FR006-CG11-SN005-DR0-HB0-7-->FR006-CG11-SN005-DR0-HB6-73: FR006-CG11-SN005-DR0-HB0-8-->FR006-CG12-SN005-DR1-HB0-8If the multicast tree is incorrect (for example, if it does not include all the expected cages),remove the file, re-ipl the CECs, and recycle CNM.Important: The output of lsnwcomponents indicates that the cluster contains a single78AC-100 frame FR006 with three supernodes: SN004 with 4x9125-F2C servers in cages7-10, SN005 with 4x9125-F2C servers in cages 11-14, and SN051 with 4x9125-F2Cservers in cages 3 - 6.
