To collect shelf logs for a DS4246 shelf in an ONTAP 9.12.1 system, you must invoke a diagnostic AutoSupport specifically targeting the storage subsystem. This action ensures that detailed storage logs, including shelf logs, are included in the AutoSupport bundle.

Use the following command:

Steps to Collect Shelf Logs:bash

Copy code

system node autosupport invoke -node -type diagnostic -subsystem storage

Replace with the name of the node experiencing the issue.

This command generates an AutoSupport message that includes logs related to storage subsystems, such as disk shelves and adapters.

Provide the AutoSupport case number to NetApp Support for further analysis.

A. Provide the output of the nodeshell command rdfile /etc/log/shelflog:

While this command allows manual reading of shelf logs, it is not a recommended or comprehensive approach for collecting logs for NetApp Support cases.

B. Invoke an AutoSupport of type all using Active IQ Unified Manager:

This action generates a generic AutoSupport bundle, which may not include detailed shelf logs unless explicitly targeted.

D. Invoke a diagnostic AutoSupport with the subsystem log_files:

The log_files subsystem targets general system logs, not storage-specific logs like shelf logs.

Why Other Options Are Incorrect:

"ONTAP 9 AutoSupport and Diagnostics Guide" outlines the use of the subsystem storage option for collecting shelf logs.

The "Troubleshooting Storage Subsystems" documentation specifies diagnostic AutoSupport as the method for gathering shelf-related logs.
