For a Dark Site customer (where Remote Assist and PhoneHome are disabled), the appropriate next step before performing a shelf evacuation is to use the evac_checks script .

Risk Mitigation: Evacuating a shelf is a resource-intensive operation that permanently removes physical capacity from the system. In a connected environment, Pure Support runs remote diagnostics to verify the array has enough free space and system resources to handle the evacuation safely.

Dark Site Procedure: Since Support cannot log in remotely, the Implementation Engineer must manually run the evac_checks python script (typically loaded via USB or available in the Purity toolkit). This script performs the equivalent validation: checking effectively used capacity, dedup ratios, and system load to predict if the remaining drives can absorb the data from Shelf 01 without filling the array to 100% or causing performance degradation. Relying solely on a generic percentage (Option B or C) is dangerous because it doesn't account for data reduction overhead or specific RAID overheads.

Following any planned maintenance event—such as a software upgrade, controller replacement, or network reconfiguration—it is a mandatory implementation step to verify that the FlashArray has successfully restored its secure outbound management connectivity to Pure Storage cloud services (Pure1).

To execute this validation on a FlashArray, the Implementation Engineer must use the purearray test command suite. Specifically, running a command like purearray test phonehome or purearray test with diagnostic flags forces the array's Callhome Connection Manager (CCM) to immediately generate and transmit a heartbeat payload to the Pure1 cloud infrastructure. If the network routing, DNS, and firewall rules are functioning correctly post-maintenance, the CLI will return a success message confirming that the payload was received by Pure Storage.

Note for clarity: While puresupport test (Option C) is a valid command within the Pure Storage ecosystem, it is strictly used on the FlashBlade (Purity//FB) operating system, not on block-optimized FlashArrays (Purity//FA).

Configuring replication involves two distinct steps: setting up the physical network interfaces (IP addresses) and then connecting the arrays (partnerships). The question specifically asks where to configure replication IP settings .

In the Purity//FA GUI, the configuration of Ethernet interfaces—regardless of their use for Management, iSCSI, or Replication—is centralized under the Settings tab, specifically within the Network sub-menu.

Settings > Network : Here, the user selects the Ethernet ports (e.g., eth2, eth3) designated for replication and assigns them IP addresses, netmasks, and gateways (or assigns them to a subnet).

Storage > Array Connections : This is where you use those configured IPs to connect to a remote array and establish the replication partnership.

Storage > Replication : This tab is used to monitor replication sessions and manage protection groups (snapshots/policies), not to configure the underlying interface IPs.

=========

To safely stop the Purity operating environment on a specific controller during a physical controller upgrade (such as upgrading from FlashArray//X to //XL or performing a chassis swap), the correct command is pureadm stop .

This command is a system administration utility located in the Linux shell of the controller (accessible via the puresh prompt when logged into the specific controller's physical IP address). It is designed to stop the local Purity services on the node where the command is executed.

Procedure: In a non-disruptive controller upgrade, the engineer manually fails over primary services to the peer controller. Then, they log into the controller designated for removal (e.g., CT0) and run pureadm stop. This ensures that all Purity processes, I/O handling, and cache operations are cleanly terminated and flushed before the hardware is physically powered down or removed.

Syntax: The pureadm tool generally operates on the local instance. Options B and C utilize invalid flags (--secondary or --controller) for this specific command context. The engineer must be physically logged into the target controller to execute the stop command for that node.
