Restore and verifying 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.
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
HA
state: ha-config show
