    Hi, 

    As you can see in the log, the ip quorum accesses only 3 nodes. There should be 4

    Thank you for your replay, but I don't understand why it only recognizes 3 IPs, My server pings all 4 IPs and gets a response.

    Hola Cuong!

    • Is the status of your 4 nodes OK?  Are you able to ssh and authenticate to all 4 nodes or only 3? Specially to the the one with IP address .121
    • Is it possible you have a duplicate IP address 192.168.70.121? You could try removing the ethernet cable and ping to the IP address
    • is the output of sainfo lsservicenodes OK?
    • Don't you see issues against eth ports if you issue lseventlog -message no
    • Don't you see any additional clue in the log file generated in /opt ? There should be a log file called ip_quorum.log.<timestamp>
    • Have you tried rebooting the node with 192.168.70.121 in the case it has a funny condition?

    Hola Cuong,

    Have you check all prerequisites in the IBM page?

    https://www.ibm.com/support/pages/node/7013877

    https://www.ibm.com/support/pages/node/7001603

    I have a host with RHEL8.8, the code in my Flashsystem is 8.7.0.0 and works with no problem. Which code has your Flashsystem?

    This is the java version:

    [17:27:18] RHEL8p8-gdlsvt7a-11:~ # java -version
    openjdk version "1.8.0_392"
    OpenJDK Runtime Environment (build 1.8.0_392-b08)
    OpenJDK 64-Bit Server VM (build 25.392-b08, mixed mode)

    Another possibility could be the linux firewall I guess...  I have it off due to it's a test environment

    Note. I don't see the IP quorum log file attached.

    Dear Cuong

    I would suggest not to use the default IP addresses of the canisters because you might run in trouble, if you bring a new machine in and you have two boxes with the same addresses. That causes confusion. In my installations i use a different network.

    Thank you for your reply, can you explain it to me in more detail?

    I only have 1 device running App IP_Quroum and 4 IP addresses of the devices.
