NEW QUESTION # 37
Which two steps are required to replace a drawer in a DS460c shelf? (Choose two.)

A. Shut down both nodes.
B. Disconnect the cable chains from the chassis.
C. Evacuate all drives in the drawer.
D. Power off the shelf.

Answer: B,C

Explanation:
To replace a drawer in a DS460c shelf, the following steps must be taken:
* Why this is required:Cable chains connect the drawer to the shelf and must be disconnected to safely remove the drawer.
1. Disconnect the cable chains from the chassis
* Why this is required:Drives must be removed to avoid damage during the drawer replacement process and to reduce the weight of the drawer for safe handling.
2. Evacuate all drives in the drawer
* A. Shut down both nodes:
* This is unnecessary because DS460c shelves support online replacement, and the system can remain operational.
* C. Power off the shelf:
* This is also unnecessary. DS460c shelves are hot-swappable, meaning they do not require the shelf to be powered down.
Why Other Options Are Incorrect:
* "DS460c Hardware Service Guide" explains the procedure for replacing a drawer.
* NetApp's "Field Replacement Guide" for DS460c shelves emphasizes online and hot-swappable replacements.

NEW QUESTION # 38
Which two tools can be used to recover an inconsistent aggregate? (Choose two.)

A. wafl_check
B. wafliron
C. file check
D. wafl snapiron

Answer: A,B

Explanation:
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.

NEW QUESTION # 39
Which two steps are required to replace a drawer in a DS460c shelf? (Choose two.)

A. Shut down both nodes.
B. Disconnect the cable chains from the chassis.
C. Evacuate all drives in the drawer.
D. Power off the shelf.

Answer: B,C

NEW QUESTION # 40
Which two commands confirm whether an aggregate is WAFL inconsistent? (Choose two.)

A. storage aggregate show
B. wafiron show <aggregate>
C. node run -node <node> sysconfig -r
D. node run -node <node> sysconfig -a

Answer: B,C

Explanation:
To determine whether an aggregate is WAFL (Write Anywhere File Layout) inconsistent, the following two commands can be used:
* 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 <aggregate> (replace <aggregate> with the name of the aggregate).
* 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.
* References:
* "WAFL Troubleshooting Guide" from NetApp highlights the wafiron show command as a primary tool for checking aggregate consistency.
1. wafiron show <aggregate>
* 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.
* References:
* "ONTAP CLI Commands Guide" specifies sysconfig -r as a method to verify aggregate status, including WAFL consistency.
2. node run -node <node> sysconfig -r
* 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.

NEW QUESTION # 41
In which two sections of AutoSupport can you find information to analyze the following panic? (Choose two.) Panic_Message: PCI Error NMI from device(s):ErrSrcID(CorrSrc(0xf00),UCorrSrc(0x18)), RPT(0,3,0):
Qlogic FC 16G adapter in slot 1 on Controller

A. PCI-HIERARCHY.XML
B. ALL-COREDUMP.XML
C. SSRAM-LOG
D. HA-RASTRACE.TGZ

Answer: C,D

Explanation:
To analyze the provided panic error, the two sections of AutoSupport that are essential for investigation are:
* What it is:HA-RASTRACE.TGZ contains HA (High Availability) system trace logs. It records hardware diagnostics, error traces, and the HA system's response to hardware events. These logs are critical when analyzing hardware-related panics, including those caused by PCI errors.
* Why it's relevant to the panic:In the given panic message, the NMI (Non-Maskable Interrupt) error originates from a Qlogic FC 16G adapter. HA-RASTRACE.TGZ will provide detailed diagnostics, including the error reporting from the HA interconnect and other hardware diagnostics. Specifically, it may include information about how the system detected the PCI fault and any actions taken to protect the system state.
* How to analyze:
* Extract the HA-RASTRACE.TGZ file from the AutoSupport bundle.
* Review hardware-related trace messages for entries associated with the PCI bus or the Qlogic FC adapter.
* Look for specific error codes or keywords like PCI Error, NMI, or Qlogic.
* References:
* NetApp's "AutoSupport Logs and Diagnostics Guide" highlights HA-RASTRACE.TGZ as a primary resource for debugging hardware faults.
* The "Panic Troubleshooting Guide" for ONTAP systems specifies HA-RASTRACE as a key source for identifying NMI-related errors.
1. HA-RASTRACE.TGZ
* What it is:SSRAM-LOG records low-level hardware error details, including PCI device register states and uncorrectable memory errors. It is particularly useful for analyzing errors originating in peripheral hardware like network or storage adapters connected via PCI.
* Why it's relevant to the panic:The panic message explicitly references a PCI Error NMI caused by a Qlogic FC adapter. SSRAM-LOG captures detailed state information for PCI devices, which can help identify whether the fault originated in the adapter hardware, the PCI bus, or another related component.
* How to analyze:
* Extract the SSRAM-LOG from the AutoSupport bundle.
* Search for PCI-related errors, including the specific error source IDs (e.g., ErrSrcID(CorrSrc (0xf00),UCorrSrc(0x18))).
* Review the log entries to confirm the root cause of the NMI.
* References:
* The "Hardware Diagnostics and Troubleshooting Guide for ONTAP" lists SSRAM-LOG as a key file for debugging PCI errors.
* NetApp's documentation on PCI diagnostics emphasizes the use of SSRAM-LOG for validating hardware-level faults.
2. SSRAM-LOG
