• Reset credentials for backup proxy configured for an ESXi host.

After we configure the backup proxy, with the intention to change the vCenter Server or the ESXi particulars, we use the vCenterDetail utility.

It bundles together with the backup proxy.

With it, we are able to view, set, and delete vCenter Server or ESXi credentials.

Transferring forward, allow us to see how you can use this utility:

1. Initially, from the vSphere Shopper console, we click on VMs and Templates.
2. Then we begin the backup proxy digital machine.
3. Later, we open a terminal on the digital machine.
4. Finally, we go surfing to the digital machine.
5. To view the vCenter Server or ESXi, username and port particulars, we run:

   1 vCenterDetail get

6. Then to set the vCenter Server or ESXi hypervisor credentials, we use:

   1 vCenterDetail set <FQDN or IP> <Username> <Password>

   Suppose, we have to set credentials for VMware setup on the cloud. Then we run:

   1 vCenterDetail set vmc <FQDN or IP> <Username> <Password>

7. Lastly, to delete the credentials of the vCenter Server or the ESXi, we run:

   view sourceprint
   1 vCenterDetail delete

• Reconfigure backup proxy settings for the vCenter server.

Contemplate we’ve got a backup proxy configured for a vCenter Server. Nonetheless, we reconfigure backup proxy settings for the vCenter server.

1. To take action, we log in to the backup proxy with root credentials utilizing the vSphere shopper.
2. Then on the command immediate, we kind ProxyConf.
3. Right here, we choose the kind of Druva Cloud by typing the quantity adjoining to the cloud.

DNS Server Person Password As soon as completed, the Druva Phoenix backup proxy makes an attempt to hook up with the DNS server. If profitable, we offer the next particulars. KDC server identify KDCport KDC username KDC Password As soon as completed, the backup proxy tries to hook up with the KDC server and generate an authentication ticket. If profitable, it will possibly hook up with the net proxy. Proxy Sort: Later, we fill within the beneath particulars accordingly. Proxy Server Proxy port Username Password
   Change the time zone	Then, we are able to change the time zone on the system.  To take action, we kind sure. From the listing of continents and oceans, we kind the quantity comparable to the server location. From the listing of nations, we kind the quantity comparable to the nation during which the server locates. Then we kind 1, to set the chosen time zone.
