Restore and verify the system configuration - FAS9500
After completing the hardware replacement, you verify the low-level system configuration
of the replacement controller, reconfigure system settings as necessary, and then run
system-level diagnostics.
Step 1: Set and verify the system time after replacing the controller module
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 replacement controller module, verify that all components display the same
HA state: ha-config show
If your system is in… The HA state for all components should be…
An HA pair ha
