Which type had to select to run ELM now

[baber]

I have installed vcsa 6.7 (using VCHA ) with embeded PSC on siteA and installed vcsa 6.7 (using VCHA) with embeded PSC on siteB now want to create ELM between them which one had to use?

1. Repoint vCenter Server with Embedded Platform Services Controller to Another vCenter Server with Embedded Platform Services Controller in a Different Domain
2. Repoint a Single Embedded Node from One Domain to an Existing Domain
3. Repoint an Embedded Node from One Domain to an Existing Domain with a Replication Partner
4. Repoint an Embedded Node to a New Domain

Hi

I believe this is what you need -

Repoint a Single Embedded Node from One Domain to an Existing Domain

Please refer the topology diagram to understand the design. Similarly, you can refer  other topologies in parent document here -

Repoint vCenter Server with Embedded Platform Services Controller to Another vCenter Server with Emb...

Hope that helps

Thanks. What does means replication here ?

Repoint an Embedded Node from One Domain to an Existing Domain with a Replication Partner

I am runing VCHA on both site . Is that OK ? not happened for VCHA ?

[ashilkrishnan]

Replication: When you join 2 PSCs in a SSO domain, the become replication partners and the information is replicated between them. That's the reason you would see both vCenter servers and it's inventory listed under one Web client interface.

vCenter part of VCHA can be configured for ELM:

vCenter Enhanced Linked Mode for a vCenter Server Appliance with Embedded Platform Services Controll...

Now I had to use this instruction :

Repoint a Single Embedded Node from One Domain to an Existing Domain

[baber]

Actually I see his command

cmsso-util domain-repoint -m pre-check --src-emb-admin Administrator --replication-partner-fqdn FQDN_of_destination_node --replication-partner-admin PSC_Admin_of_destination_node --dest-domain-name destination_PSC_domain

my vcsa FQDN for siteA is labvcsa.opr.dsa and my FQDN is SiteB is lvcsa.opr.dsa 

and my domain for vcsa login for both site is vsphere.local I login with Administrator@vsoere.local  How can above command with my info ?

[ashilkrishnan]

For '--dest-psc-fqdn' : Provid FQDN of 2nd vCenter

For '--replication-partner-admin': Provide SSO admin username for 2nd vCenter

For syntax and definitions of other arguments, you can refer this document:

Syntax of the Domain Repoint Command

As I understood replication means and use for sync between two PSCs and in all of ELM's type we have two PSCs

1- is that correct or not ?

2- due install Vcenter in both side I use vsphere.local  now according to follow command :

cmsso-util domain-repoint -m pre-check --src-emb-admin Administrator --replication-partner-fqdn FQDN_of_destination_node --replication-partner-admin PSC_Admin_of_destination_node --dest-domain-name destination_PSC_domain

Is dest-domain-name = vsphere.local ?

3 - What is my destination_PSC_domain ?

[ashilkrishnan]

Hi

1. Yes, that's correct

2. Command syntax looks good

3. Destination PSC domain will be vsphere.local

[baber]

Thanks.

But my issue in the first step is with Replication concept if replication means sync between two PSCs in all types of ELM we need replication thus why there are :

Repoint an Embedded Node from One Domain to an Existing Domain with a Replication Partner

Repoint a Single Embedded Node from One Domain to an Existing Domain

in both of them we have PSC and after join PSC had to do replication for sync between them

What is difference between them ?

BR

[ashilkrishnan]

First one contains existing replication partners. Nodes A,B,C are linked, however node D is standalone.

Second one shows 2 standalone vCenter servers and after re-pointing they are both under 'Domain2.local' SSO domain

[baber]

1-  Is that your means in the "Repoint an Embedded Node from One Domain to an Existing Domain with a Replication Partner" two or 3 vcsa previously joined to same domain and now we want add new vcsa to previous vcsas  ?

2- and in the "Repoint a Single Embedded Node from One Domain to an Existing Domain " we installed one vcsa and now want join second vcsa to previous vcsa ?

Is that correct ?

But finally as we use PSC in all modes cannot understand the Replication beacuse in all types we have PSC and had to use replication and sync between them

Would you please help me ?
