FRUs on FAS9000 Supporting Replacement Without Takeover:

A (I/O Module): I/O modules can be replaced hot (without takeover) to maintain system uptime during hardware servicing.

D (NVRAM Module): NVRAM modules on FAS9000 can also be replaced without a node takeover, ensuring data integrity during replacement.

Why Other Options Are Incorrect:

B (DCPM Module): The DCPM (Data Center Power Management) module is not hot-swappable and requires a node takeover.

C (Caching Module): The caching module is integrated and typically requires a node takeover or power-down for replacement.

NetApp Reference Documentation:

Refer to the 'NetApp FAS9000 Hardware Service Guide' for supported FRU replacement procedures and operational constraints.

When a node panics in ONTAP, a kernel core file is generated. This core file contains information about the kernel's state at the time of the panic and is essential for debugging system crashes.

Key Details:

A kernel core file is produced during a node panic to capture information about the kernel, memory, and processes that led to the crash.

The core file is stored on the root aggregate by default and can be uploaded to NetApp Support using the autosupport invoke-core-upload command.

Why Other Options Are Incorrect:

A . mgwd core:

This is related to the Management Gateway daemon, which handles management traffic. It does not generate a core file during a panic.

B . user space core:

User space cores are generated for processes running in user space, not for kernel panics.

C . sync core:

Sync cores refer to synchronized cores for debugging but are not the primary type generated during a node panic.

'ONTAP Panic Troubleshooting Guide' specifies kernel core files as the output of a node panic.

'ONTAP Core File Management Guide' details the handling of kernel core files after a crash.

When ONTAP detects a WAFL inconsistency in an aggregate, it automatically generates an AutoSupport message with the description WAFL INCONSISTENT BLOCK.

Key Details:

WAFL INCONSISTENT BLOCK:

This error indicates that WAFL metadata or user data blocks have been found to be inconsistent.

ONTAP triggers an automatic AutoSupport message to notify administrators and NetApp Support.

Why Other Options Are Incorrect:

A . MEDIUM ERROR DURING RECONSTRUCTION:

This error occurs during disk reconstruction, not due to WAFL inconsistencies.

B . CHECKSUM ERROR:

A checksum error indicates a disk-level data integrity issue, not a WAFL inconsistency.

C . WAFL INCONSISTENT USER DATA BLOCK:

While related, this is not the specific AutoSupport message triggered by ONTAP.

NetApp 'ONTAP WAFL Troubleshooting Guide' describes AutoSupport messages related to WAFL inconsistencies.

In maintenance mode, the command disk show --v provides detailed information about disk ownership. This includes the current owner, previous owner, and disk health status.

How to Use:

Enter maintenance mode, and run:

disk show --v

The output will display ownership information for each disk, including its RAID group and current assignment.

Why Other Options Are Incorrect:

A . sysconfig --v:

This command provides system configuration details but does not show disk ownership.

C . aggr status:

This command shows the status of aggregates, not individual disks or their ownership.

D . storage show disk --p:

This command is not valid in maintenance mode.

NetApp 'Maintenance Mode Commands Guide' highlights disk show --v as the command to check disk ownership.

Command Syntax for Downloading ONTAP Image:

The cluster image package get command is used to download the ONTAP image from a specified URL to the cluster's image repository.

The syntax requires the --url parameter followed by the full URL of the image file.

Why Option C Is Correct:

This command syntax directly downloads the image from the local web server at http://192.168.10.10/ to the ONTAP cluster repository.

Other options either refer to incorrect commands or unsupported URLs.

NetApp Reference Documentation:

The 'ONTAP Software Upgrade Guide' provides the exact command and steps for downloading ONTAP images via HTTP or FTP.
