HPE2-T37 Sample Questions & Answers

Standard LACP (802.3ad) operates between a single device and another single device. To create a LAG that spans two physically separate upstream switches, those switches must support a proprietary or standards-based technology that makes them appear as a single logical switch to the downstream device (HPE Virtual Connect). This technology is commonly known as Multi-Chassis Link Aggregation (MLAG), Virtual PortChannel (vPC), or Virtual Switching System (VSS), depending on the vendor.

The Server Profile is the central construct in HPE OneView that encapsulates the entire server identity, including firmware, BIOS settings, network connections (MAC addresses), and SAN connections (WWNs). By abstracting this personality from the physical hardware, OneView allows the profile to be moved to any compatible compute module, which then assumes that identity. This is the essence of stateless computing.

The correct approach for an existing server is to create a server profile from a template, but before applying it, use the option to import the server's current configuration into the profile. This allows OneView to 'Manage' the server for firmware and health monitoring while ensuring that the initial profile application does not alter the server's production settings. This effectively puts the server under management without being disruptive.

HPE GreenLake for Compute Ops Management offers a cloud-based console that provides a unified management experience for HPE servers. When integrated with OneView, it allows administrators to perform tasks like firmware management and health monitoring across globally distributed sites from a single, secure web portal, simplifying management at scale.

Within the server profile's SAN storage section, each attached volume has a 'Boot' property. This must be explicitly enabled for the intended boot volume. This action ensures that the server's HBA is configured to see this LUN as a bootable target.

The Synergy management ring is designed with redundancy. A single failure (e.g., a bad cable or a failed Frame Link Module) breaks the ring, triggering a 'Redundancy Lost' alert. The system automatically re-routes management traffic the other way around the ring. The environment remains fully manageable, but it is now operating in a non-redundant state, and a subsequent failure could isolate one or more frames from management.

The 'Orchestrated' activation policy for interconnects tells HPE OneView to update redundant modules sequentially. It will update one Virtual Connect module, wait for it to come back online and for network paths to stabilize, and then proceed to update the second module. This ensures that at least one interconnect is always active, maintaining server connectivity throughout the update process.

A Network Set is a logical grouping of multiple individual Ethernet networks (VLANs). This allows an administrator to quickly assign a large number of networks to a server profile's network connection (as a trunk) instead of adding them one by one, simplifying management for hypervisor hosts or other servers requiring access to many VLANs.

For HPE Synergy, the Composer appliance acts as the central aggregation point for all hardware within the frames it manages. Remote Support must be configured and enabled on the Composer, which then reports issues for all its managed components (frames, interconnects, compute modules). If the Composer is not registered, no devices within the Synergy frames will have automatic case creation.

HPE Remote Support requires a valid and active support contract (like Proactive Care) for the hardware in question. If the service entitlements for the Synergy frames or compute modules have expired or are not correctly associated with the account used for registration, HPE's backend systems will reject the automated case creation requests.

This is a key feature of HPE's composable infrastructure. A server profile can be assigned to an empty device bay. This pre-provisions the bay's network and storage connections. When a compatible compute module is later inserted into that bay, HPE OneView will automatically apply the full profile configuration to the new hardware.
