How to perform VCenter 4.0 linked mode between two sites ?

Hi All,

How to join two VCenter into linked mode between my Production and DR site ?

so that I don't have to open two separate vSphere client for both sites.

1. You must have the standard edition of vCenter, link mode is not a feature of foundation or essentials.

2. It installs ADAM, to replicate data between the sites (VC servers).

3. If you re-run the VC installation from the cdrom, it will guide you through the installation.

4. It will detect the current running VC instance, and ask you to Join another Instance.

5. Enter the fqdn of the VC you want to Link to, so make sure you can reach it across WAN, via ping, and check latency is good.

6. It will also Modify, and fix Linked Mode Conflict Resolution if asked reply yes.

The biggest issue I find, is trying to find the original cdrom with VC 4.0 software.

ah, that sounds simple, "original cdrom with VC 4.0 software." --> you can just download it again from the VMware website.

Can I do this during the office hour or it requires downtime for the VCenter only ?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
yes, you can just download again from the web, that's what we do, because we can never find the damn cdroms, and it's often quicker than looking for them in the cabinents!

I would always recommend, any changes to virtual infrastructure, scheduled downtime is arranged.

But it does depend on how many Administrators and Users of vSphere vCenter you have, because if it sometimes restarts services or in usualy Windows fasion, asks for a restart, which it can do on some occasions, everyone would lose contact with vCenter.
