Pass the Pure Storage FAIS FlashArray-Implementation-Specialist Questions and answers with Dumpstech

During a controller upgrade (e.g., //X to //XL), the puresetup script attempts to migrate network configurations from the old controller's ports to the new controller's ports. If the script detects that certain ports configured on the source array are physically missing or "link down" on the target array, it halts to prevent a configuration mismatch that could cause a service outage.

The error message explicitly lists the affected ports. The correct resolution path is to:

Identify the services:Determine if the missing ports are critical (e.g., a replication link that hasn't been cabled yet) or non-critical (e.g., an unused interface).

Re-run with override:Execute the puresetup command again, this time appending the specific flags or arguments (often suggested in the error output or upgrade guide) to explicitly acknowledge and include those affected ports. This tells the script, "I know these ports are down/missing; proceed with the migration anyway."

This allows the upgrade logic to complete the configuration transfer so the new controller can boot, after which the engineer can physically troubleshoot the link status.

=========

To initiate a Purity Operating Environment (OE) software upgrade from the Command Line Interface (CLI), the correct command ispureinstall.

pureinstall: This command manages the upgrade workflow. It typically takes an image file (ISO) as an argument or downloads it from the repository, unpacks it, performs pre-flight checks, and then applies the update to the controllers in a non-disruptive rolling fashion.

purereboot is used to restart a controller or the array but does not install software.

puresetup is used for the initial configuration of network settings and array names, not for software updates.

=========

To verify the history and transmission status of Phonehome log bundles, the correct command ispurearray phonehome --list.

Before starting a controller upgrade (NDU), it is mandatory to ensure that the array can successfully transmit diagnostic data to Pure Storage. This allows Support to review the "pre-flight" checks and ensures that if an issue occurs during the upgrade, logs will be available for triage.

Usage:Running purearray phonehome --list displays a table of recent log bundles generated by the system.

Verification:The Engineer must look at the Status column for the most recent entries. A status of"uploaded"confirms that the array has successfully connected to the Pure Storage cloud and transferred the data. If the status is "queued" or "failed," the upgrade should not proceed until network connectivity (firewall/proxy) is resolved. Options A and C are incorrect CLI syntax for this specific verification task.

When adding a second DirectFlash Shelf to aFlashArray//XL, the connectivity utilizesPCIe Slot 6(in conjunction with Slot 0).

FlashArray//XL Architecture:The //XL chassis distributes its backend NVMe-oF (100GbE RoCE) connectivity across two dedicated PCIe slots to ensure redundancy and maximum bandwidth. As established in hardware diagrams,Slot 0(lower riser) andSlot 6(upper riser) are the designated slots for the 2-port 100GbE backend cards.

Expansion Logic:

First Shelf:Typically connects to Port 0 of the card in Slot 0 and Port 0 of the card in Slot 6 (providing HA).

Second Shelf:Connects to the remaining ports (Port 1) on thesame cardsin Slot 0 and Slot 6.

Exam Context:In the context of "which slot must be used" for the expansion or specifically highlighting the secondary backend slot distinct from the primary host slots,Slot 6is the correct identifier for the backend expansion capability on the //XL. Options A (Slot 0) is the primary, but C (Slot 6) is often the specific answer required to demonstrate knowledge of the //XL's unique split-riser backend layout compared to legacy arrays.

The output "Ping successful with CCM" is a specific success message returned by the puresupport test or purearray test connectivity checks.CCMstands forCloud Connection Manager, which is the internal service or endpoint responsible for mediating the secure connection between the local FlashArray and thePure1cloud management platform.

When an Implementation Engineer sees this message, it confirms that the array can successfully resolve and reach the Pure1 infrastructure over the internet (specifically the pure1.purestorage.com or associated regional endpoints). This validates that:

DNS is functioning correctly (resolving the CCM hostname).

Firewall rules are permitting outbound HTTPS (port 443) traffic.

The array's management interface is routing correctly.

This connection is vital for "Phone Home" logs, Remote Assist sessions, and fleet management via the Pure1 mobile app or dashboard. It is distinct from the Fusion Fleet Coordinator (which manages fleet logic) and the cross-controller interconnect (which is internal hardware communication).

=========

A valid transfer path forre-using iSCSI cardsduring a controller upgrade is from aFlashArray//XR2 to a FlashArray//XR3(Option A).

Hardware Continuity:The FlashArray//XR2 and //XR3 generations share a high degree of physical component compatibility, particularly regarding PCIe form factors and supported interface cards.

Upgrade Workflow:When performing an "Intra-Series" upgrade (refreshing just the controllers from R2 to R3 to gain CPU performance), the existing I/O cards (Fibre Channel or iSCSI) from the R2 chassis can typically be transferred directly into the new R3 controllers.

Legacy Limitations:Migrating cards from a much olderFlashArray//M(Option B or C) is generally restricted. The //M series often used older generation PCIe cards or different form factors (like onboard risers) that are not validated or physically compatible with the modern PCIe slots found in the //X series. Therefore, for //M to //X upgrades, new I/O cards are usually required, whereas R2 > R3 supports reuse.

To meet the requirement of deploying a specific, newer Purity version (6.1.21) on a factory-fresh array that arrived with older code (5.3.8), the most efficient and correct procedure for an Implementation Engineer is tocreate a bootable USB stick with the target 6.1.21 ISO and reimage the controllers.

The "Factory Reset" or re-imaging process is a supported method for initial installation when the desired software baseline differs significantly from what is pre-loaded. Since the array contains no customer data yet, re-imaging is non-destructive to business operations and avoids the time-consuming process of initializing the array on old code, registering it, and then performing a multi-step software upgrade (Option C).

Procedure:The engineer downloads the specific Purity ISO from the Pure Storage Support portal, uses a tool like Rufus or Etcher (or the pureinstall utility) to create the bootable media, and boots the controllers from this USB to lay down the fresh image.

Option Bis incorrect because copying .ppkg files is part of anonline upgradeworkflow for running systems, not a re-imaging process for a raw box.

On aFlashArray//XR2 or //XR3controller equipped with an optional Ethernet Mezzanine (EMEZZ) card, the additional ports are enumerated asETH6, ETH7, ETH8, and ETH9.

The port numbering logic on these controllers follows a strict sequence:

ETH0 and ETH1:Fixed onboard 1GbE Management ports.

ETH2 and ETH3:Fixed onboard 10/25GbE ports (often used for replication or iSCSI).

ETH4 and ETH5:Reserved or used by the first PCIe slot expansion (if populated with Ethernet).

ETH6 through ETH9:Assigned to theEthernet Mezzanine (EMEZZ)slot.

The EMEZZ is a specific internal slot distinct from the standard PCIe risers. When populated, the Purity operating system reserves the eth6–eth9 block for these interfaces. Options B and C are incorrect because they describe port ranges that would typically be assigned to PCIe expansion cards in Slot 1 or Slot 2 (e.g., eth10+), or they simply do not align with the hardcoded enumeration logic of the R2/R3 controller architecture. Correct identification of these interfaces is critical for configuring link aggregation (LACP) or assigning iSCSI IPs during the initial setup.

The customer should proceed via theSelf-Service Upgrade (SSU)portal available onPure1 Manage.

Pure Storage has transitioned significantly toward a self-service model for routine software upgrades to provide customers with greater flexibility and immediacy.

Pure1 Manage:This cloud-based management platform includes a "Software Lifecycle" or "Upgrade" widget. It automatically checks the array's health, compatibility, and readiness for various Purity versions.

Process:The customer can select the target Purity version directly in the portal. Pure1 then orchestrates the "Pre-Flight Checks" (Remote Audit) to ensure the array is healthy. Once passed, the Purity software is downloaded directly to the array, and the customer (or the engineer) can trigger the upgrade at their convenience without needing to schedule a specific window with a live Support engineer.

Invalid Options:Options A and B describe legacy or unsupported workflows. Customers do not manually download Purity ISOs to USB drives or run raw pureinstall CLI commands manually; these methods lack the automated safety checks and cloud-based verification provided by the SSU ecosystem.

To expand a FlashArray//X10 from a5/5(fully populated chassis with two 5TB equivalent packs) to an11/11(two 11TB equivalent packs) configuration, the correct action is toinstall a swing shelf with loan capacity.

The Constraint:The "5/5" notation implies the chassis slots are already occupied by the existing media. Since the customer isreplacingthe existing packs with larger ones (Capacity Consolidation) rather than just adding new ones, the engineer needs a place to put the data during the swap.

Why Swing Shelf:The FlashArray//X10 chassis has limited slots. You cannot simply pull a pack (Option A) if the remaining pack doesn't have enough free space to hold all the data (which is typical in upgrade scenarios). ASwing Shelf(temporary external SAS or NVMe shelf provided by Pure) is attached to the array. The data is evacuated from the internal drives to this shelf. Once the internal slots are empty, the new 11TB packs are installed. The data is then moved back from the shelf to the new packs, and the shelf is removed.
