Issue/Introduction

Symptoms:

• While configuring vSphere Replication error appears:

  

• NTP configured on vSphere Replication server
  
  

Environment

VMware vSphere replication 8.x

1. Login to vSphere Replication VAMI -> Select NTP.

2. Select the Time zone and edit. For Time Synchronization select edit and enable NTP.

3. Enter the NTP server IP or hostname, click save.

4. Repeat the same steps for vCenter Server using VAMI.

5. Using vSphere replication VAMI , Summary - >Configure Appliance run Configuration.

6. Fill Details necessary and use "Finish" to complete the configuration step.

Workaround:

Steps to change the date and Time of SRM/VR manually

1. Capture vCenter server appliance date and time,

$ watch date - this output gives current time.

Note: the same command needs to be run on other appliances having issues.

2. To manually change use below command

$ date --set="YY-MM-DD HH:MM:SS" 

3. Restart NTP services,

$service ntpd stop

$service ntpd start

$service ntpd status
