  • 1.  powervc server unreachable

    Posted 08/01/22 09:23 AM
    Hi, everyone
    I experienced issues with powervc 2.0.3
    PowerVC is installed on a single node rhel 8.6
    I can't acces the powervc server after changing IP node address and VIP address,
    all powervc services are up and running

    I experienced the same situation with PowerVC 2.0.2.1.
    Just restarted PowerVC (powervc-services stop/start command) and it cleared the situation.
    I am wondering what the cause is...

    [root@xxxxx]# cat /etc/pam.d/su
    #%PAM-1.0
    auth required pam_env.so
    auth sufficient pam_rootok.so
    # Uncomment the following line to implicitly trust users in the "wheel" group.
    #auth sufficient pam_wheel.so trust use_uid
    # Uncomment the following line to require a user to be in the "wheel" group.
    #auth required pam_wheel.so use_uid
    auth substack system-auth
    auth include postlogin
    account sufficient pam_succeed_if.so uid = 0 use_uid quiet
    account include system-auth
    password include system-auth
    session include system-auth
    session include postlogin
    session optional pam_xauth.so

    It is change IP and VIP scenario. Right?

    Have you restarted the services with
    powervc-services restart

    Actually, we did not change IP nor VIP.
    But experienced network interruption among PowerVC and vHMC, Storage, VIOS, SAN-SW.
    Can this cause this kind of error?
    Anyway, PowerVC restart (stop and start) resolved the problem.
    Thank you.
