    SRM Install failure - SRMhost/vCenter time skew issue

    dbutch1976 Hot Shot

      Hello,

       

      I'm having an issue installing SRM 6.0.0-2700495 in my vCenter 6 environment vCenter Server 6.0.0, 2776510 (appliance).

       

      There error is:

       

      The time skew between the Site Recovery Manager host and the vCenter Server is too large.

       

      This is very odd since I set both the vCenter appliance and the host that it's running on are configured to use an NTP server (time.windows.com).  I have also tried setting the vCenter appliance to sync its time with the host.  As you can see from the screenshot, there does appear to be a time sync issue of approximately 5 minutes.

       

      Any suggestions?  Is this error just another red herring or do I have an actual time sync issue??

       

      Thanks.

          That is almost certainly the problem. In 6.0, SRM is much more sensitive to time skew and 5 minutes is likely to be too much.

            I have placed the vCenter in the correct time zone now by using the following process:

             

            Enable SSH in the vCenter 6 appliance console
            Enable BASH in the vCenter 6 appliance console
            Putty in the vCenter 6 appliance
            Enter root/PW

            Type 'shell'
            putty into the vCenter 6 appliance
            Enter the root/PW

            Enter the following commands:

            ls /usr/share/zoneinfo/US/
            *  This will display the list of available time zones, in my case I needed Eastern, replace with your time zone
            cd /
            cd etc
            rm localtime
            ln -s /usr/share/zoneinfo/US/Eastern localtime
            date

            * Verify that you are now displaying the correct date and time.
            ** Optionally you can set the appliance to use an NTP server by using the following command:

            sntp -P no -r time.windows.com

             

            I am still having the exact same problem even though the ESXi host and the vCenter6 appliance are now perfectly synced for time.  After doing more digging I see that when I putty into the host and type 'date' I get a totally different result then what I'm seeing in the host details within vCenter itself.  Keep in mind, this in the same host displaying two different time settings, any idea why?

             

             

            The commands I used to set the time zone within the appliance do not work on an ESXi host, however this has already been set correctly within the GUI, why would I need to set it in both places anyway??

              Just ran into the same issue. My time sync was only off by about 45 seconds. I changed the local server time to be as close as possible (within 1 or 2 seconds) and the installer let me proceed.

                I'm not sure why, but this issue seems to have just vanished on its own.  I haven't been able to reproduce it since I initially encountered it.
