Setting and verifying system time after replacing the controller
You should check the time and date on the replacement controller module against the healthy controller
module in an HA pair. If the time and date do not match, you must reset them on the replacement controller
module to prevent possible outages on clients due to time differences.
It is important that you apply the commands in the steps on the correct systems:
• The replacement controller is the new controller that replaced the degraded controller as part of this
procedure.
• The healthy controller is the HA partner of the replacement controller.
Step 1.
In admin privilege on the replacement controller, check the system time on the controllers:

The date and time are displayed for all controllers in the cluster.
Step 2.
If necessary, set the time on the replacement controller to match the healthy controller:
modify -dateandtime "target_date_and_time"
Step 3.
Check the date and time from the replacement controller:
Step 4.
Exit admin privilege.
Completing the replacement process
After you replace the part, you can return the failed part to Lenovo, as described in the RMA instructions
shipped with the kit. Contact technical support at
additional help with the replacement procedure.
Important information after replacing the controller module
Important: Please contact your Lenovo support personnel to obtain replacement licenses for your new
controller.
Replacing a DIMM
You must replace a DIMM in the controller module when your system registers an increasing number of
correctable error correction codes (ECC); failure to do so causes a system panic.
Before you begin
All other components in the system must be functioning properly; if not, you must contact technical support.
You must replace the failed component with a replacement FRU component you received from your
provider.
