If you miss the prompt and the controller module boots to ONTAP, enter halt, and then at the
LOADER prompt enter
boot_ontap, press Ctrl-C when prompted, and then boot to Maintenance
mode.
During the boot process, you might see the following prompts:
▪ A prompt warning of a system ID mismatch and asking to override the system ID.
▪ A prompt warning that when entering Maintenance mode in an HA configuration you must ensure
that the healthy controller remains down.
You can safely respond
y to these prompts.
e. Select the option to boot to Maintenance mode from the displayed menu.
Restore and verify the system configuration - AFF C190
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:
show date
The date and time are given in GMT.
3.
At the LOADER prompt, check the date and time on the replacement node:
show date
The date and time are given in GMT.
4.
If necessary, set the date in GMT on the replacement node:
set date mm/dd/yyyy
5.
If necessary, set the time in GMT on the replacement node:
set time hh:mm:ss
6.
At the LOADER prompt, confirm the date and time on the replacement node:
show date
The date and time are given in GMT.
