To invoke AutoSupport in ONTAP, the following tools can be used:

How to use:Run the command:

1. CLI (Command Line Interface)python

Copy code

autosupport invoke -node -type all

This triggers AutoSupport to collect and send logs and system information.

How to use:Log in to the Active IQ portal and use its interface to request an AutoSupport message from the connected ONTAP systems.

2. NetApp Active IQ website

A. NetApp Cloud Insights:

This tool is used for monitoring and performance analysis, not for triggering AutoSupport messages.

D. the SmartSolve tool:

SmartSolve is used for case resolution guidance but does not invoke AutoSupport.

Why Other Options Are Incorrect:

"ONTAP AutoSupport Guide" provides instructions for invoking AutoSupport via CLI and Active IQ.

The identifier 1.2.3.L1 follows the NetApp disk naming convention, which specifies the location of the drive in the system. Here is the breakdown of the identifier:

1: This indicates the stack ID or loop ID. It represents the stack number in the disk shelf configuration.

2: This indicates the shelf ID. In this case, the drive is located in shelf 2.

3: This indicates the bay ID or slot number within the shelf. The drive is in bay 3.

L1: This represents the logical port or logical disk identifier.

The shelf ID is 2, so the drive is in shelf 2 (A is correct).

The bay ID is 3, so the drive is in bay 3 (B is correct).

C. The drive is in bay 2: The bay ID is explicitly specified as 3, not 2.

D. The drive is in shelf 1: The shelf ID is clearly given as 2, not 1.

NetApp Hardware Universe documentation provides details on disk naming conventions.

The "ONTAP Disk Management Guide" includes a full explanation of disk IDs and their interpretation.

To recover an inconsistent aggregate, the following tools can be used:

What it does:This tool is used to perform a consistency check on WAFL metadata. It identifies and attempts to fix WAFL inconsistencies in aggregates.

When to use:Run wafl_check after identifying WAFL inconsistencies to repair minor metadata issues.

1. wafl_check

What it does:This tool repairs WAFL inconsistencies by reconstructing metadata. It is more powerful than wafl_check and should only be run under NetApp Support guidance, as improper use can result in data loss.

When to use:Use wafliron for severe WAFL inconsistencies that cannot be resolved by wafl_check.

2. wafliron

A. file check:

This is not a valid NetApp tool.

C. wafl snapiron:

While similar in name, snapiron is used for snapshot recovery, not aggregate recovery.

Why Other Options Are Incorrect:

"ONTAP Aggregate Troubleshooting Guide" details the usage of wafl_check and wafliron.

NetApp Support documentation provides guidelines for recovering inconsistent aggregates.

To diagnose a PCI/NMI error and collect logs, use the following commands:

What it does:This command collects PCI error logs, including detailed information about PCI devices and the errors that caused the panic.

How to use:Run the command from the nodeshell to capture the required PCI log entries.

1. pelog –a –g=2

What it does:This command reads the SSRAM log file, which contains low-level error information related to PCI and other hardware subsystems.

How to use:Run the command to view the log entries directly for detailed troubleshooting.

2. rdfile /mroot/etc/log/SSRAM

B. show pci –v:

While this command displays PCI device information, it does not provide detailed error logs.

D. event log show:

This displays event log entries but does not contain the specific PCI or NMI-related logs required for diagnosing the panic.

Why Other Options Are Incorrect:

"ONTAP Hardware Troubleshooting Guide" lists pelog and SSRAM as tools for analyzing PCI errors.

"ONTAP Panic Analysis Guide" emphasizes the importance of collecting detailed hardware logs.
