NEW QUESTION # 165
An Implementation Engineer has completed a hardware NDU, but after the upgrade, Purity reports a "health not responding" status when running status. Before contacting support, which command should the Implementation Engineer run to review a list of possible logged issues?
Answer: C
Explanation:
After a complex operation like a Hardware Non-Disruptive Upgrade (HWNDU), the Purity health services may occasionally stall or report generic errors like "health not responding." Standard alert commands (purealert list) might be empty or show generic "service unavailable" messages because the alerting service itself depends on the health system.
To troubleshoot this, the Implementation Engineer should dig deeper into the system's internal message log using puremessage list --open --hidden.
puremessage accesses the raw message bus of the array, which captures lower-level events than standard alerts.
--hidden is the critical flag here; it reveals internal system messages that are typically suppressed from the standard user view to avoid noise.
These hidden messages often contain the specific error codes or service failure reasons (e.g., "timeout waiting for daemon X") that explain why the health status is hanging. Providing this output to Pure Support significantly accelerates the root cause analysis. purearray diagnose is not a standard command for this purpose, and purealert watcher is for configuring notification recipients, not viewing log contents.
NEW QUESTION # 166
An Implementation Engineer is performing a FlashArray//XR4 to FlashArray//XL upgrade, and is preparing to remove the XR4 CT0 controller.
Which command should the Implementation Engineer run to stop Purity after confirming CT0 is the secondary controller?
Answer: B
Explanation:
During a complex cross-generational Hardware Non-Disruptive Upgrade (HWNDU) from a FlashArray//XR4 to a FlashArray//XL, the Implementation Engineer must carefully orchestrate the shutdown and removal of the legacy compute nodes. Before physically unlatching and removing the CT0 controller, the Purity//FA operating system processes running on that specific node must be gracefully halted.
Because standard user commands do not allow for this level of low-level service manipulation, the engineer must utilize the purewes (Wessex) command-line suite. Wessex is the internal engineering toolkit used to override high-availability states during hardware replacements.
The correct command to execute is purewes controller disable --purity --verify-mode secondary --verify- array < ARRAY_NAME > ct0 .
This command contains several critical safety mechanisms. The --purity flag specifies that the script should shut down the Purity storage processes rather than just network interfaces. The --verify-mode secondary flag is a mandatory safeguard; it checks the cluster state to guarantee that CT0 has already successfully failed over its active host I/O responsibilities to CT1. If CT0 is still the primary controller, the command will intentionally fail to prevent an accidental storage outage. Finally, --verify-array ensures the engineer is executing this disruptive command on the correct physical array, which is crucial when multiple SSH sessions are open in a busy datacenter.
NEW QUESTION # 167
When installing the first DirectFlash Shelf on a FlashArray//XR2/3, what mezzanine ports are used on the controllers?
Answer: A
Explanation:
When installing the first DirectFlash Shelf on a FlashArray//XR2/3, mezzanine ports ETH6 and ETH9 on the controllers are used for connectivity.
NEW QUESTION # 168
During a FlashArray//X to FlashArray//XL hardware upgrade, when should the Implementation Engineer insert the DFMd modules into the FlashArray//XL?
Answer: B
Explanation:
Upgrading from a FlashArray//X to a FlashArray//XL involves a significant architectural change, often requiring a data migration or a specific "chassis replacement" workflow known as a Data-in-Place upgrade where the new chassis temporarily acts as an expansion shelf. In this specific procedure, the new FlashArray
//XL chassis is not immediately populated with its final drives (DFMDs) before power-on because it first needs to be configured to accept data or join the cluster in a controlled state.
The procedure requires the Implementation Engineer to boot the FlashArray//XL chassis first and configure it into Shelf Mode (SPM) . Only after the chassis is successfully running in this mode-effectively acting as a passive SAS/Ethernet attached shelf to the existing controllers-are the DirectFlash Modules (DFMd) inserted.
Inserting them earlier could cause the array to attempt a full boot sequence or initialize a new array instance, complicating the upgrade logic. By waiting until Shelf Mode is confirmed, the engineer ensures that the modules are recognized correctly as part of the migration target resources, allowing Purity to manage the layout and data redistribution correctly from the source array.

NEW QUESTION # 169
An Implementation Engineer needs to upgrade Purity to version 6.9.2 on a FlashArray. The .ppkg file was too large to fit on a USB stick as a single file and has been copied to the array as two split files.
How should the Implementation Engineer join the files into a single file to be installed?
Answer: A
Explanation:
When upgrading PurityOS on a Pure Storage FlashArray, the upgrade package file (.ppkg) is heavily compressed but still quite large, typically ranging between 6GB and 12GB depending on the version. Often, Implementation Engineers use a USB flash drive to transfer these upgrade files directly to the array's controllers, especially in dark sites where network-based file transfers are restricted.
However, standard USB flash drives are usually formatted with the FAT32 file system to ensure broad compatibility across different operating systems. FAT32 has a strict maximum file size limit of 4GB. Because the single Purity .ppkg file exceeds this limitation, engineers must split it into smaller chunks (usually using the Linux split -b command, which generates sequential files with suffixes like aa, ab) before copying them to the USB drive.
Once the split files are successfully transferred into the /home/puresetup/ directory on the FlashArray controller, they must be properly reassembled into the original, functional .ppkg binary. Because Purity runs on a custom Linux kernel, standard Linux CLI utilities apply here. The correct and officially supported method to achieve this is using the cat (concatenate) command. By running cat with the wildcard * on the split file names, the system sequentially reads the chunks in alphabetical order and redirects ( > ) the binary output to recreate the single, unified .ppkg file. Using join, tar, or zip will either fail to execute or corrupt the binary package entirely.
