Hi,
Yes you can connect new VCenter(its shows some warning, ignore that)... if u get error like this" this host connect in the different VCenter. then you need to restart the vpxa service in two esx host , if get again error you need to remove the vmware-vpxa in two host, after that it should connect to new VCenter..
how to uninstal vmware-vpxa in host:-
1.
Disconnect the ESX host in VirtualCenter. Right-click the host and click Disconnect.
2.
Log in as root to the ESX host using an SSH client.
3.
Paste the following string of commands into the SSH session:
service mgmt-vmware stop && service vmware-vpxa stop && service vmware-vmkauthd stop && service xinetd restart && rpm -qa | grep -i vpxa | awk '{print $1}' | xargs rpm -ef $1 && userdel vpxuser && rpm -qa | grep -i aam | awk '{print $1}' | xargs rpm -ef $1 && service mgmt-vmware start && service vmware-vmkauthd start
Note: This is a concatenated list of commands strung together with the "&&" operator. This is useful in stringing together multiple commands as the next command does not start until the previous one has completed successfully.
Here is a description of the commands:
4.
*
The service mgmt-vmware stop && service vmware-vpxa stop && service vmware-vmkauthd stop && service xinetd restart command stops the management services for the service console.
*
The rpm -qa | grep -i vpxa | awk '{print $1}' | xargs rpm -ef $1 command removes the vpxa agent.
*
The userdel vpxuser command removes the vpxa user that gets installed once you connect the host to VirtualCenter.
*
The rpm -qa | grep -i aam | awk '{print $1}' | xargs rpm -ef $1 command removes the AAM RPM (HA) which gets reinstalled when you configure HA.
*
The service mgmt-vmware start && service vmware-vmkauthd start command following restarts the services.
*
The vmware-cmd -l command lets you know when hostd is up and running so you can reattach it to VirtualCenter.
Note: When you see a list of virtual machines output, the command sequence is complete.
5.
Log in to the VirtualCenter Server using VMware Infrastructure (VI) Client.
6.
Choose the ESX host from the Inventory.
7.
Right-click on the ESX host and click Connect. This step initiates a re-install of the agent.
To reinstall the VMware HA components:
Log in as root to the ESX service console.
Type rpm -qa | grep -i aam
This returns two packages that are named similar to:
*
VMware-aam-haa-#.#.#-#
*
VMware-aam-vcint-#.#.#-#
Remove these packages using rpm -e followed by the name of one of the returned packages. Repeat for both files.
Run the command:
rpm -qa | grep -i vpxa
A package named VMware-vpxa-#.#.#-##### is returned.
Remove this package using rpm -e followed by the name of one of the returned packages.
Test adding the host to the newly created Vcenter to see if this has resolved the issue.
