NEW QUESTION # 19
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. SSRAM-LOG
- B. ALL-COREDUMP.XML
- C. HA-RASTRACE.TGZ
- D. PCI-HIERARCHY.XML
Answer: A,C
Explanation:
To analyze the provided panic error, the two sections of AutoSupport that are essential for investigation are:
1. HA-RASTRACE.TGZ
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.
2. SSRAM-LOG
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.
NEW QUESTION # 20
After replacing a failed controller, the engineer notices mismatched firmware versions between HA partners. What is the BEST action?
- A. Disable storage failover permanently
- B. Synchronize firmware to supported compatible versions
- C. Downgrade all disk firmware immediately
- D. Ignore the mismatch permanently
Answer: B
Explanation:
Firmware consistency across HA partners ensures stable failover behavior and hardware compatibility. Supported compatible versions should be synchronized according to NetApp procedures. Permanent failover disablement is unnecessary. Disk firmware downgrades are unrelated unless specifically identified in interoperability guidance.
NEW QUESTION # 21
During a new SVM deployment, all of the FC LIFs are showing an admin/oper status of up/down.

- C. Wipe your config and restore from backup.
- D. Reinstall your boot media and install ONTAP 9.5 software.
Answer: C,D
Explanation:
Reverting to a previous ONTAP version requires careful preparation because ONTAP upgrades often introduce irreversible changes. To successfully revert, the following actions are needed:
C). Reinstall your boot media and install ONTAP 9.5 software
You need to reinstall the older version of ONTAP (9.5) on the boot media because the current version (9.7) has been installed as part of the upgrade. The reinstallation ensures that the system boots with ONTAP 9.5.
Steps:
Boot the node into maintenance mode.
Perform the reinstallation using the appropriate ONTAP 9.5 image.
D). Wipe your config and restore from backup
A revert requires wiping the configuration because ONTAP upgrades may have made changes to the cluster configuration or WAFL metadata. Restoring the configuration from a backup ensures consistency with the older ONTAP version.
Steps:
Back up the current cluster configuration before proceeding.
Use the restored backup after the revert is complete to reconfigure the system.
