Issue/Introduction
You are unable to perform a new site pairing in SRM/VLSR and are receiving errors when trying to find the peer vCenter server on step 2.
"Unable to acquire token from SSO server at 'https://vcfqdn/sso-adminserver/sdk/vsphere.local'."
Environment
VMware Live Recovery 9.X
Cause
This issue is occurring due to issues with the SRM appliance attempting to contact the target vCenter appliance.
/opt/vmware/support/logs/dr-client/dr.log will show the following errors complaining about network routing to the target vCenter:
"com.vmware.srm.client.topology.impl.vmomi.TokenProvider$AcquireTokenFailed: Unable to acquire token from SSO Server at 'https:/xxxxxxxxxxxx/sso-adminserver/sdk/vsphere.local'.""No route to host: targetvcfqdn"
Resolution
Ensure network connectivity between Site Recovery Manager and target vCenter server over port 443.
- Perform an nslookup from the SRM appliance SSH session to the target vCenter server using FQDN and then a reverse lookup using IP address
- If "No route to host" errors are present. Ensure the DNS servers are correct on both SRM and vCenter Servers, ensure proper forward and reverse lookups exist
- In the case of limited networking between sites or DNS routing, add the details of the target vCenter into the SRM appliances /etc/hosts file and the details of SRM into the target vCenter /etc/hosts file.
- Perform a curl test from the SRM appliance ssh session to the target vCenter server to verify port 443 is open
- Ensure there are no issues with time drift between appliances
