VCS Learning : Learn about Cluster Hearbeats

Ramdev

I have started unixadminschool.com ( aka gurkulindia.com) in 2009 as my own personal reference blog, and later sometime i have realized that my leanings might be helpful for other unixadmins if I manage my knowledge-base in more user friendly format. And the result is today's' unixadminschool.com. You can connect me at - https://www.linkedin.com/in/unixadminschool/

    Hi Ram,

    Thanks for this nice post,

    I have some confusion on these outputs , please correct me if i am wrong,
    step2 : if those two interfaces connected properly with each other you will see below output and

    And if you suspect cross connection use the other heartbeat interface to ping the dlpiping server interface. And if the outputt shows sent / received success as below, then you know that the heartbeat cables connected wrongly

    Thanks in advance

    Hi Srinivas –

    actual connection:

    gurkulvcs1 : e3   <----> gurkulvcs2 : e3
    gurkulvcs1 : e4   <----> gurkulvcs2 : e4

    Initially i have started the dlpiping service on “gurkulvcs1 : e3”

    test 1 : ping from gurkulvcs2 : e3  to gurkulvcs1:e3 — if success the connections are connected straight and as expected

    test 2: ping from gurkulvcs2 : e3  to gurkulvcs1:e3 — if failed then there might be two issues one is the nework cable  second one is cross connection. In the next step we will see if there is any cross connection

    test 3 : ping from gurkulvcs2 : e4  to gurkulvcs1:e3 : -if success , then it means the cables are crossed as below.

    gurkulvcs1 : e3   <----> gurkulvcs2 : e4
    gurkulvcs1 : e4   <----> gurkulvcs2 : e3

    hope that helps.
