Which two commands confirm whether an aggregate is WAFL inconsistent? (Choose two.)
To determine whether an aggregate is WAFL (Write Anywhere File Layout) inconsistent, the following two commands can be used:
1. wafiron show
What it does: This command directly checks the WAFL consistency status of the specified aggregate. If an aggregate is WAFL inconsistent, it will report the inconsistency in the output.
How to use:
Run the command: wafiron show
Look for indications of WAFL inconsistency in the output.
Why it's relevant: The wafiron utility is specifically designed to provide WAFL status and diagnostics. It is the most accurate and direct way to confirm whether an aggregate is inconsistent.
'WAFL Troubleshooting Guide' from NetApp highlights the wafiron show command as a primary tool for checking aggregate consistency.
2. node run --node <node> sysconfig --r
What it does: This command displays RAID information for all aggregates on the specified node. If an aggregate is WAFL inconsistent, it will be explicitly mentioned in the output.
How to use:
Run the command: node run --node <node> sysconfig --r.
Check the output for the phrase 'WAFL inconsistent' under the corresponding aggregate.
Why it's relevant: This command provides additional context, such as the RAID group details, which can help understand whether the inconsistency is isolated or part of a larger issue.
'ONTAP CLI Commands Guide' specifies sysconfig --r as a method to verify aggregate status, including WAFL consistency.
Why Other Options Are Incorrect:
C . storage aggregate show:
This command displays aggregate configuration and usage information but does not report WAFL inconsistency.
D . node run --node <node> sysconfig --a:
While this command shows detailed hardware configuration information, it does not include WAFL consistency status for aggregates.
