The Ops Center Automator task and alert occurrence times are based on the management server time setting. Therefore, it is important that you verify the accuracy of the server OS time setting and reset it if necessary before installing Ops Center Automator. If you change the Ops Center Automator server time while the Common Component and Common Component product services are running, Ops Center Automator might not operate correctly.

Important: The Ops Center Automator server OS time setting must synchronized with the management servers running Common Component products and Ops Center products.
Note: When Common Services and Automator are running on different hosts, launching Automator from the Ops Center portal fails if there is a time lag of more than three minutes between the host where Common Services is installed and the host where Automator is installed. You must synchronize the time on the Common Services host with the time on the Automator host. Use NTP to keep the time synchronized between the hosts.

If you plan to use a service such as NTP, which automatically adjusts the server time, you must configure the service as follows:

  • Configure the settings so that the time is adjusted when the service discovers a time discrepancy.
  • The service adjusts the time setting only as long as the time difference remains within a specific range. Based on the maximum range value, set the frequency so that the time difference never exceeds the fixed range.

An example of a service that can adjust the time as long as the time difference does not exceed a fixed range is the Windows Time service.

Note: When running Ops Center Automator in a U.S. or Canadian time zone, you must configure the management server OS so that it supports the new Daylight Savings Time (DST) rules. Ops Center Automator cannot support the new DST rules unless the server gives support.

If you cannot use the functionality that adjusts the server time automatically, or to manually change the system time, perform these steps:

  1. Stop the Common Component and all Common Component product services, for example:
    • HBase 64 Storage Mgmt Web Service
    • HBase 64 Storage Mgmt Web SSO Service
    • HBase 64 Storage Mgmt SSO Service
    • HBase 64 Storage Mgmt Common Service
    • HCS Device Manager Web Service
    • HiCommand Suite Tuning Manager
    • HiCommand Performance Reporter
    • HCS Tuning Manager REST Application Service
    • HAutomation Engine Web Service
    • HiCommand Server
    • HiCommand Tiered Storage Manager
  2. Record the current time of the management server, and then reset the time.
  3. Determine when to restart the services.
    • If you set the time of the machine back (meaning that the server time was ahead), wait until the server clock shows the time you recorded (the time on the server when you made the change) and then restart the machine.
    • If you set the machine time forward, restart the machine now.

Verify that the Ops Center Automator management server reflects the correct time.
