Chassis
Overview of chassis replacement - AFF A400
To replace the chassis, you must move the fans and controller modules from the impaired
chassis to the new chassis of the same model as the impaired chassis.
All other components in the system must be functioning properly; if not, you must contact technical support.
• You can use this procedure with all versions of ONTAP supported by your system.
• This procedure is disruptive. For a two-node cluster, you will have a complete service outage and a partial
outage in a multinode cluster.
Shut down the controllers - AFF A400
Shut down or take over the impaired controller using the appropriate procedure for your
configuration.
Option 1: Shut down the controllers when replacing a chassis
This procedure is for 2-node, non-MetroCluster configurations only. If you have a system with more than two
nodes, see
How to perform a graceful shutdown and power up of one HA pair in a 4-node cluster.
Before you begin
You need:
• Local administrator credentials for ONTAP.
• NetApp onboard key management (OKM) cluster-wide passphrase if using storage encryption.
• SP/BMC accessability for each controller.
• Stop all clients/host from accessing data on the NetApp system.
• Suspend external backup jobs.
• Necessary tools and equipment for the replacement.
If the system is a NetApp StorageGRID or ONTAP S3 used as FabricPool cloud tier, refer to the
Gracefully shutdown and power up your storage system Resolution Guide after performing this
procedure.
If using FlexArray array LUNs, follow the specific vendor storage array documentation for the
shutdown procedure to perform for those systems after performing this procedure.
If using SSDs, refer to SU490: (Impact: Critical) SSD Best Practices: Avoid risk of drive failure
and data loss if powered off for more than two months
As a best practice before shutdown, you should:
• Perform additional
system health checks.
• Upgrade ONTAP to a recommended release for the system.
•

Make note of any faults presently on the system, such as LEDs on the system components.
