Before configuring the Cloud Mobility feature, the embedded Management and Cloud Mobility applications will need to have their system time synchronized to a Network Time Protocol (NTP) server. The maximum time drift allowed is a 5-minute difference between Cloud Mobility and the cloud providers. The NTP server is configured in the eManagement vApp Manager for PowerMax 2000 and 8000, and in the Unisphere 10 serviceability tab for PowerMax 2500 and 8500.
The NTP server IP address will be configured as part of the PowerMax and Cloud Mobility installation service. The steps below can be used to verify or modify the IP address of the NTP server.
Note: The NTP server should not be changed while snapshots are shipping or recovering. The Reset Config should not be used on systems with Cloud Mobility. To change NTP servers, use the Set Config function.
On a PowerMax 2000 and 8000, the eManagement vApp Manager is used to display the current IP address of the NTP server configured. To display the current IP address configured:
On a PowerMax 2500 and 8500, the Unisphere serviceability management is used to display the current IP address of the NTP server configured. To display the current IP address configured:
Note: Changing the IP subnet after the Cloud system has been set up would require Dell Support engineering.
