5. With the cam handle in the open position, slide the controller module into the chassis and firmly push the
controller module in until it meets the midplane and is fully seated, and then close the cam handle until it
clicks into the locked position.
Do not use excessive force when sliding the controller module into the chassis; you might
damage the connectors.
The controller module begins to boot as soon as it is fully seated in the chassis.
6. Repeat the preceding steps to install the second controller into the replacement chassis.
7. Boot each controller.
Restore and verify the configuration - AFF A900
To complete the chassis replacement, you must complete specific tasks.
Step 1: Verifying and setting the HA state of the chassis
You must verify the HA state of the chassis, and, if necessary, update the state to match your system
configuration.
1. In Maintenance mode, from either controller module, display the HA state of the local controller module and
chassis:
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:
ha-config modify chassis ha-state
The value for HA-state can be one of the following:
▪ ha
▪ non-ha
3.
Confirm that the setting has changed:
ha-config show
4. If you have not already done so, recable the rest of your system.
Step 2: Bring up the system
1. If you have not done so, plug the power cables back into the PSUs.
2. Turn on the PSUs by toggling the rocker switched to ON, and wait for the controllers to power up
completely.
3. Check the front and the back of the chassis and controllers for any fault lights after power up.
4. Connect to the SP or BMC IP address of the nodes via SSH. This will be the same address used to shut
down the nodes.
5. Perform additional health checks as described in
How_to_perform_a_cluster_health_check_with_a_script_in_ONTAP
6.
Turn AutoSupport back on (end the maintenance window message):
system node autosupport invoke -node * -type all -message MAINT=end
