Resolution

Q: What does the 'Client cluster mount check' check do? 

• This check is to verify if there is a client cluster mounting the datastore of the vSAN cyber recovery cluster.

Q: What does it mean when it is in an error state?

• If this test returns red, it means there is no client cluster configured for the vSAN cyber recovery cluster.

Note: vSAN cyber recovery won’t work without a client cluster configured, which is needed to run VMs during recovery.

Q: How does one troubleshoot and fix the error state?

• To address this error, configure a client cluster mounting the datastore of the vSAN cyber recovery cluster with the following steps:

1. 1. Prepare a vSAN HCI cluster or vSAN compute cluster as the client cluster for this vSAN cyber recovery cluster.
   2. Navigate to the client cluster's Configure tab, select vSAN > Datastore Management.
   3. Click 'Mount Remote Datastore', select the datastore of the vSAN cyber recovery cluster, and then complete the mounting process.
