  • 1.  HOSTS from Cluster disconned

    Posted Sep 21, 2013 01:56 PM

    Hi

    I have 2 HOSTS in cluster with HA activ and I have power some VMs and moved other VMs to 2. HOSTS. I power 1. HOSTS Down and change Memory modul in server from 32GB to 64GB. After start of 1. HOSTS I could see en vCenter Manager that HOSTS 1 is disconneted. I try to connect but after 2min server was disconnected Again.

    I stoped HA in cluster and removed both HOSTS while 2. HOSTS also disconnected.

    But nothink helps to connet HOSTS to vCenter Cluster.

    Both HOSTS is running with other problems.

    Can you help me ?

    Sorry i did not get what you are trying to tell.

    Now both the hosts are diconnected from vCenter? What error does it throw when you try to connect the hosts?

    I can add HOSTS 1 and 2 into the cluser Again but after 1min both HOSTS get disconnected in vCenter

    No error at add but after 1 min I get status change from normal to disconnected hosts

    Direct connection Works fine

    Which version of vSphere (vCenter Server/hosts) are you running?

    Please double check DNS name resolution and ensure vCenter Server is able to resolve the host's FQDN and vice versa.

    NO - all settings is OK all DNS and forwared is OK from all vCenter and from Hosts. Ports are open (902).
    I can see some error on storage system but system is running - and on direct host all Things look allright - SO ..... NO NOT FIXed yet :smileysad:

    First your esxi version is low currently it is 1065491 and vcenter is 1123966 so update it. before upgrade this, u can try one thing just disconnect the esxi from cluster and do the following stapes.

    1.cp /opt/vmware/uninstallers/VMware-fdm-uninstall.sh /tmp
    2. chmod +x /tmp/VMware-fdm-uninstall.sh
    3. /tmp/VMware-fdm-uninstall.sh

    then reboot host and add esxi on cluster. if problem not solved then upgrade esxi and vc.
