Restore and verify the system configuration - AFF A220 and FAS2700
After completing the hardware replacement and booting to Maintenance mode, you verify
the low-level system configuration of the replacement controller and reconfigure system
settings as necessary.
Step 1: Set and verify 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, or against a reliable time server in a stand-alone configuration. 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.
About this task
It is important that you apply the commands in the steps on the correct systems:
• The replacement node is the new node that replaced the impaired node as part of this procedure.
• The healthy node is the HA partner of the replacement node.
Steps
1. If the replacement node is not at the LOADER prompt, halt the system to the LOADER prompt.
2. On the healthy node, check the system time:
The date and time are given in GMT.
3. At the LOADER prompt, check the date and time on the replacement node:
The date and time are given in GMT.
4. If necessary, set the date in GMT on the replacement node:
5. If necessary, set the time in GMT on the replacement node:
6. At the LOADER prompt, confirm the date and time on the replacement node:
The date and time are given in GMT.
Step 2: Verify and set the HA state of the controller module
You must verify the HA state of the controller module and, if necessary, update the state to match your system
configuration.
1. In Maintenance mode from the new controller module, verify that all components display the same
state:
ha-config show
The HA state should be the same for all components.
2. If the displayed system state for the chassis does not match your system configuration:
a. Set the HA state for the chassis:
The value for HA-state can be one of the following:
54
show date
set date mm/dd/yyyy
set time hh:mm:ss
ha-config modify chassis HA-state
show date
show date
