Re: How to move simplivity cluster to new vCenter

Hi Saloris

Thank you for coming on HPE Community forums,

You will have to create new Datacenter, cluster in the new VCenter. Then discover the nodes. Once they are added, they have to update the vcenter by running dsv-update-vcenter command on each OVC. This has to be done on one OVC at a time. It will reboot the OVC, once the operation is done

Hope this helps.!!

Hello Mahesh202,

Thanks for your reply.  

Is there any action need done in original vCenter A? like delete or disconnect host, cluster ? 

or we need do nothing in vCenter A,  all operation need done in vCenter B.

Re: How to move simplivity cluster to new vCenter

Hello @saloris 

In the original cluster you first need to disconnect the host to stop managing it on vCenter A. Once you have it configured in vCenter B and after running the "dsv-update-vcenter" command on the OmniStack controllers, then you can remove it from inventory.

Also, have in mind that to be able to run this dsv command you need to elevate to root privileges in the OmniStack controller. If you are running 3.7.3 and above use these commands:

1. "sudo su"

2. "source /var/tmp/build/bin/appsetup

3. dsv-update-vcenter --username <vcenter username> --server <new vcenter ip>

Hope this helps, 

Thanks

Re: How to move simplivity cluster to new vCenter

Hello Gustenar,

Base  your suggestions, I summarized the steps as below:

1. disconnect two Exsi host in the original cluster on vCenter A.

2. create new cluster with same name on vCenter B, add two Exsi host to this cluster

3. run below command on the Omnistack controller to update OVC to vCenter B.

sudo su

source /var/tmp/build/bin/appsetup

dsv-update-vcenter --username <vcenter username> --server <new vcenter ip>

4. remove the Exsi host in the original cluster on vCenter A

5. delete the original cluster on vCenter A.

If no more attention, we will arrang  change to do it.   thanks so much.

Create the new cluster first on vCenter B. Move one host at a time.

Re: How to move simplivity cluster to new vCenter

I have 2 clusters that I need to move to a new vCenter server, but I also need to change the host names of the ESXi hosts.  Is there a best way to do one first before the other?

Thank you,

Re: How to move simplivity cluster to new vCenter

I would say the order does not really matter. To change the host name you can use the command:

"svt-host-rename --from oldhostname --to newhostname"
