NetApp FAS22 Series User manual

Replacing the chassis on a FAS22xx system
To replace the chassis, you must remove the power supplies, hard drives, and controller module or modules from the old
chassis, remove the old chassis from the equipment rack or system cabinet, install the new chassis, and then reinstall the
components into the new chassis.
Before you begin
All other components in the system must be functioning properly; if not, you must contact technical support.
About this task
• You can use this procedure with all versions of Data ONTAP supported by your system.
In this procedure, a
Cluster-Mode system refers to a system running Data ONTAP 8.x in Cluster-Mode. A 7-Mode system
refers to a system running Data ONTAP 8.x in 7-Mode.
• This procedure refers to HA pairs , which in releases prior to Data ONTAP 8.0 were called active/active configurations .
• This procedure assumes you are moving all disk drives to the new chassis.
• This procedure is written with the assumption that the chassis is nonfunctional and, therefore, the controller modules in it are
not serving data.
• This procedure is written with the assumption that you are moving the controller module or modules to the new chassis, and
that the chassis is a new component from NetApp.

Running diagnostics on the chassis
After installing a new chassis, you should run diagnostics. If your system is in an HA configuration, you should run the tests
separately on both nodes.
Steps
1. Enter the following command at the LOADER prompt:
boot_diags
Note: You must enter this command from the LOADER prompt for system-level diagnostics to function properly. The
boot_diags command starts special drivers designed specifically for system-level diagnostics.
The Maintenance mode prompt (*>) appears.
2. Enter the following command at the Maintenance mode prompt:
sldiag
For details about the sldiag command, see the sldiag man page.
3. Clear the status logs by entering the following command:
sldiag device clearstatus
4. Verify that the log is cleared by entering the following command:
sldiag device status
The following default response is displayed:
SLDIAG: No log messages are present.
5. Run the environmental diagnostics test by entering the following command from the Maintenance mode prompt:
sldiag device run -dev env
6. View the status of the test by entering the following command:
sldiag device status
Your storage system provides the following output while the tests are still running:
There are still test(s) being processed.
After all the tests are complete, the following response appears by default:
*> <SLDIAG:_ALL_TESTS_COMPLETED>
7. Verify that no hardware problems resulted from the addition or replacement of hardware components on your system by
entering the following command:
sldiag device status [-dev devtype] [-name device] -long -state failed
System-level diagnostics returns you to the prompt if there are no test failures, or lists the full status of failures resulting
from testing the component.
