Part 2 – Configure SRM Mappings & Pair SRM

In our previous blog, we had deployed our two SRM appliances and now we will start to pair them so we can do some failover/failback operations using the SRM.

Step 1. Launch our production site SRM portal https://IP_address and click on Launch Site Recovery

Step 2. Choose our local vCenter as our production site. Because all my vCenters are linked and under the same SSO domain we will choose the Pair type as Option 2

Step 3. Select the DRAAS vCenter as our peer vCenter and Click Next

Step 4. As expected, we will now notice that SRM Services are enabled on our SRM appliance so we will click Next to continue

Step 5. We will get a warning about the certificates on the recovery side SRM appliance and vCenter Server appliance, Click Connect

Step 6. Review settings and click Finish

Step 7. Logout and log back into our vCenter and we can now see our Site Recovery is now linked.

Step 8. Open Site Recovery manager via https://srm01.ash.local

Step 9. In order to use SRM, we will need to have the following mappings in place

Network Mappings
Folder Mappings

Resource Mappings
Storage Policy Mappings
Placeolder Datastore

Create network mappings

Step 1. Browse to Configure – Network Mappings and Choose New

Step 2. Choose automatically prepare mappings

Step 3.Select the production and DRAAS networks as shown and click on Add Mappings. This is actually the mapping from our Production VLAN to our DRAAS vLAN which enables us to failover VM’s from our Prod to DRAAS site

Step 4. Now we should see the newly added mapping listed

Step 5. We will now need a reverse mapping for failback operations so this will be prepopulated for us as per what we choose In the previous step

Step 6. A test network is used for simulated failover tests. ie: If we don’t wish to failover our VM’s fully and just would want to verify if our DR works, we can simulate a failover to a test network. Here it says it will auto-create an Isolated network and will use that for simulated failovers.

Step 7. Review and click Finish to complete the network mapping wizard

Step 8. We should see the new network mapping listed.

Step 9. We can easily apply IP customisations here to direct our prod VM’s onto a specific IP range.

Step 10. A rule has been defined that will map IP addresses in the 172.16.11.0 network on our Prod site to addresses in the 172.16.99.0 network on our DRAAS site.

All prod VM’s will be automatically assigned an IP on the 172.16.99.0 range with a new gateway and DNS as shown below.
