Running system-level diagnostics
After installing a new caching module, you should run diagnostics.
Before you begin
Your system must be at the LOADER prompt to get to the maintenance menu to start System Level
Diagnostics.
All commands in the diagnostic procedures are issued from the controller where the component is being
replaced.
Step 1. If the controller to be serviced is not at the LOADER prompt, perform the following steps:
a. Select the option to boot to Maintenance mode by typing halt
b. Once at the LOADER prompt, type boot_ontap menu
c. When the system appears at the selection menu, choose option 5 to go into Maintenance
mode.
Step 2. Run diagnostics on the caching module: sldiag device run -dev fcache
Step 3. Verify that no hardware problems resulted from the replacement of the caching module: sldiag
device status -dev fcache -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.
Step 4. Proceed based on the result of the preceding step:
