What's new for ONTAP Select 9.19.1

Source: https://docs.netapp.com/us-en/ontap-select/reference_new_ots.html

ONTAP Select 9.19.1 ships two headline features for software-defined ONTAP: (1) Support for external key management via KMIP — ONTAP Select now supports an external KMIP key manager (e.g., SafeNet, Thales, Vormetric) for NVE encryption keys. Cloud key managers (AWS KMS, Azure Key Vault, GCP KMS) are explicitly NOT supported — only on-prem KMIP. Enable post-deploy via the management GUI or REST API; existing 9.19.1 clusters gain the option after upgrade. (2) Support for AMD processors on both KVM and ESXi hypervisor hosts — previously Intel-only. The KVM hypervisor path is now viable on AMD EPYC servers (important for modern server fleets that have largely moved off Intel Xeon SP). Both features have been requested heavily by SMB customers running ONTAP Select on commodity hardware and by orgs standardising on AMD for sustainability/perf reasons. Prior major releases: 9.18.1 simplified product downloads to two artifacts (ONTAP Select Deploy + ONTAP Select Image, replacing the legacy 4-image matrix), 9.17.1 added NVMe-oF support on KVM, 9.16.1 brought 100GbE support. Reference for any ONTAP Select capacity planner / hardware refresh conversation.

FAS70 to DS212C shelf connectivity clarification

Source: https://community.netapp.com/community/discussion/468369/need-clarity-on-on-fas70-to-ds212c-shelf-connectivity

A field engineer asked which cabling diagram to follow when connecting a FAS70 controller to two DS212C shelves, citing the FAS70/90 install-cable doc (https://docs.netapp.com/us-en/ontap-systems/fas-70-90/install-cable.html) which shows DS460C connectivity and the SAS3 cabling rules (https://docs.netapp.com/us-en/ontap-systems/sas3/install-cabling-rules.html) for platforms without internal storage. The point that often confuses new installers: the FAS70/90 install-cable page references DS460C as the example topology because that's the recommended high-density shelf, but the port-pair rules for SAS3 multipath HA are identical for DS212C (12Gb SAS, IOM12C). The official answer in the thread confirms that for an HA-pair FAS70 with 2× DS212C: use both controllers' ports 0a/0b and 0c/0d (4 SAS lanes per controller) with multi-path HA cabling — each shelf IOM connects to both controllers in a square so any single IOM, HBA, or cable failure doesn't drop the shelf. Reference for FAS/DS212C installation how-to.

Cable the FAS70 or FAS90 hardware for network and storage connectivity

Source: https://docs.netapp.com/us-en/ontap-systems/fas-70-90/install-cable.html

Canonical NetApp doc for cabling a FAS70 or FAS90 HA pair (new 2025-2026 generation FAS entry/mid-tier). Step 1: connect the storage controllers to your data network — each FAS70/FAS90 controller ships with onboard 100GbE ports (e0a/e0b on a dedicated NIC) plus optional PCIe NIC slots; standard practice is one LACP bond pair for data and a separate management L2. Step 2: cable host-network connections (iSCSI, NFS, SMB client traffic) — use dedicated NICs/slots, never share with intercluster or NDU. Step 3: cable management-network connections to the service-processor/management switch — the FAS70/90 nodes expose a dedicated 1GbE management port plus the RJ-45 SP. Step 4: cable the shelf connections — SAS3 (12 Gb/s) multipath HA to supported DS212C/DS224C/DS460C shelves using IOM12C modules. The doc emphasises the multipath square: each controller's ports 0a/0b/0c/0d connect to both shelves' IOM-A and IOM-B, so any single IOM, HBA, cable, or controller failure doesn't drop the shelf. This is the exact topology a field engineer was confused about in community thread 468369 — the FAS70/90 example shows DS460C, but the rules are identical for DS212C and DS224C; only port counts and lane counts differ. Useful install reference for any 2026 FAS deployment.

S&P Global's Innovative DR Strategy Using Amazon FSx for NetApp ONTAP Snapshots

Source: AWS Big Data Blog

AWS published an architectural case study detailing how S&P Global built a multi-region disaster recovery solution for SQL Server workloads running on Amazon FSx for NetApp ONTAP, using ONTAP's native snapshot technology plus SnapMirror to replicate the FSx file systems cross-region. The design relies on consistent application-aware snapshots via the FSx ONTAP REST API (`/api/protocols/snapmirror/relationships` and `/api/storage/volumes/{id}/snapshots`) so that VSS-equivalent quiescing happens before the snapshot is taken, then the snapshots are replicated to a secondary FSx ONTAP instance in the DR region. Recovery time objectives (RTO) hit sub-60 minutes because the SnapMirror destination is kept near-current and the SQL Server databases are mounted from the secondary FSx volume rather than being restored from backup.

Managing NetApp ONTAP with Ansible Automation Platform [TR-1462-2]

Source: NetApp

NetApp released a refreshed technical report (TR-1462-2) covering end-to-end automation of ONTAP cluster operations through Red Hat Ansible Automation Platform (AAP). The report walks through installing `netapp.ontap` collection from Ansible Galaxy, configuring the ONTAP REST API credential (`/api/cluster` and `/api/security`), and using Ansible Controller (Execution Environments with `python 3.11` + `netapp-lib`) to drive day-1 (cluster setup, SVM create, NFS/SMB export policy) and day-2 (volume create, snapshot policy, SnapMirror schedule, quota report) workflows. The -2 revision adds AAP 2.5 workflow job templates and inventory plug-ins, plus integration with ONTAP's webhook notifications (`/api/support/auto-support/events`) so Ansible can react to ASUP events and run remediation playbooks automatically.

Flex Unified ONTAP-mode General Availability

Source: NetApp

NetApp announced the general availability of "Flex Unified ONTAP-mode" — a new deployment mode that consolidates SAN (iSCSI/FC) and NAS (NFS/SMB) protocols on the same FlexVol volume while exposing a unified management plane via ONTAP System Manager. The new mode replaces the prior protocol-licensing friction where enabling both SAN and NAS on a single SVM required a feature license key swap; Flex Unified mode activates all four protocols at cluster create time and lets admins carve LUNs and shares from the same aggregate. ONTAP 9.16.1+ is required. Documentation note: cluster peers should still use `cluster peer create` and SVM peering remains a separate workflow — the only change is the unified licensing envelope.

Protect ONTAP consistency groups

Source: https://docs.netapp.com/us-en/ontap/consistency-groups/protect-task.html

Creating a consistency group does not automatically enable protection. Protection policies can be set at the time of creation or after creating your consistency group. You can protect consistency groups using: SnapMirror active sync (referred to as SnapMirror Business Continuity in versions of ONTAP before 9.15.1) If you are utilizing nested consistency groups, you can set different protection policies for the parent and child consistency groups. Beginning with ONTAP 9.11.1, consistency groups offer two-phase consistency group snapshot creation . The two-phase snapshot operation executes a pre-check, ensuring the snapshot is captured successfully.

ONTAP S3 architecture using FlexGroup volumes

Source: https://docs.netapp.com/us-en/ontap/s3-config/architecture.html

Access to the bucket is provided through authorized users and client applications. When a bucket is used exclusively for S3 applications, including use as a FabricPool endpoint, the underlying FlexGroup volume will only support the S3 protocol. Beginning with ONTAP 9.12.1, the S3 protocol can also be enabled in multiprotocol NAS volumes that have been preconfigured to use NAS protocols. When the S3 protocol is enabled in multiprotocol NAS volumes, client applications can read and write data using NFS, SMB, and S3. Minimum bucket capacity is determined by the ONTAP platform.

Configure external directory services for ONTAP S3 access

Source: https://docs.netapp.com/us-en/ontap/s3-config/configure-access-ldap.html

You can provide user groups belonging to an external directory service with access to your ONTAP object storage environment. Lightweight Directory Access Protocol (LDAP) is an interface for communicating with directory services, such as Active Directory, that provide a database and services for identity and access management (IAM). To provide access, you need to configure LDAP groups in your ONTAP S3 environment. After you have configured access, the group members have permissions to ONTAP S3 buckets. For information about LDAP, see Learn about using LDAP name services on ONTAP NFS SVMs . You can also configure Active Directory user groups for fast bind mode, so that user credentials can be validated and third-party and open-source S3 applications can be authenticated over LDAP connections. Ensure the following before configuring LDAP groups and enabling the fast bind mode for group access: An S3-enabled storage VM containing an S3 server has been created. See Create an SVM for S3 .

Configure a hierarchical ONTAP consistency group

Source: https://docs.netapp.com/us-en/ontap/consistency-groups/configure-hierarchy-task.html

Hierarchical consistency groups have a parent that can include up to five individual consistency groups. Hierarchical consistency groups can support different local snapshot policies across consistency groups or individual volumes. If you use a remote protection policy, that will apply for the entire hierarchical consistency group (parent and children). Beginning with ONTAP 9.13.1, you can modify the geometry of your consistency groups and move volumes between child consistency groups . For object limits on consistency groups, see Object limits for consistency groups . When creating a hierarchical consistency group, you can populate it with new LUNs. Beginning with ONTAP 9.13.1, you can also use new NVMe namespaces and NAS volumes.

Assess ONTAP S3 physical storage requirements

Source: https://docs.netapp.com/us-en/ontap/s3-config/assess-physical-storage-requirements-task.html

When you create an S3 bucket in an S3-enabled SVM, a FlexGroup volume is automatically created to support the bucket. You can let ONTAP select the underlying aggregates and FlexGroup components automatically (the default) or you can select the underlying aggregates and FlexGroup components yourself. If you decide to specify the aggregates and FlexGroup components — for example, if you have specific performance requirements for the underlying disks — you should make sure that your aggregate configuration conforms to best practice guidelines for provisioning a FlexGroup volume. Learn more: NetApp Technical Report 4571-a: NetApp ONTAP FlexGroup Volume Top Best Practices If you are serving buckets from Cloud Volumes ONTAP, it is strongly recommended that you manually select the underlying aggregates to ensure that they are using one node only. Using aggregates from both nodes can impact performance, because the nodes will be in geographically separated availability zones and hence susceptible to latency issues.

Add or remove volumes to an ONTAP consistency group

Source: https://docs.netapp.com/us-en/ontap/snapmirror-active-sync/add-remove-consistency-group-task.html

In most instances, this is a disruptive process requiring you to delete the SnapMirror relationship, modify the consistency group, then resume protection. Beginning with ONTAP 9.13.1, adding volumes to a consistency group with an active SnapMirror relationship is a non-disruptive operation. In ONTAP 9.9.1, you can add or remove volumes to a consistency group using the ONTAP CLI. Beginning with ONTAP 9.10.1, it is recommended that you manage consistency groups through System Manager or with the ONTAP REST API. If you want to change the composition of the consistency group by adding or removing a volume, you must first delete the original relationship and then create the consistency group again with the new composition.

Manage link costs in StorageGRID (NetApp Docs)

Source: https://docs.netapp.com/us-en/storagegrid/admin/manage-link-costs.html

StorageGRID 12.1 adds more-detailed link-cost information and settings that let operators prioritise which data-center site services a request when two or more sites exist. Link costs directly influence traffic-engineering decisions for the ADC service, load balancer placement, and object routing; mismatched costs are a common root cause of unexpected WAN egress or elevated latency between sites after topology changes. New in 12.1: explicit per-link settings and reporting that surface which sites are being preferred for which workflows, useful when validating multi-site deployments for AI factories that want to keep hot data close to GPU pools.

Misplaced or Forgotten OKM Passphrase During Hardware Replacement (NetApp Knowledge Base)

Source: https://kb.netapp.com/on-prem/ontap/Ontap_OS/OS-KBs/Misplaced_or_Forgotten_OKM_Passphrase_During_Hardware_Replacement

Recovery procedure for clusters whose Onboard Key Manager (OKM) passphrase was lost or never recorded during a controller / NVRAM / DIMM replacement. Walks through using `security key-manager onboard show-graphics` (modern) / `security key-manager onboard sync` and the OKM card / companion CLI to restore the passphrase against the OKM database, with explicit warnings that mis-typing the passphrase silently re-keys storage and locks out data access if fewer than the quorum of cards are still present. Important reference for any field engineer replacing an AFF/FAS head where NSE/NAE volumes exist — losing the OKM passphrase with no backup is unrecoverable without engaging NetApp TAC.

REST API reference for the AFX storage system (ONTAP AFX docs)

Source: https://docs.netapp.com/us-en/ontap-afx/rest/api-reference.html

The AFX REST API reference is the authoritative source for every endpoint exposed by AFX storage systems, surfaced as a Swagger/OpenAPI document that can be loaded directly into API tooling. It is the primary automation entry point for AFX — replacing what classic ONTAP administrators would have done with the ONTAP CLI or the ZAPI interface — and is the recommended path for orchestrating bucket, storage-unit, and protection operations against an AFX cluster from external automation (Ansible, Terraform, custom controllers). For data-platform teams wiring pipelines to land AI training data into AFX S3 buckets, this is the contract that the platform team should pin in their IaC modules.

Manage the AFX storage system buckets (ONTAP AFX docs)

Source: https://docs.netapp.com/us-en/ontap-afx/manage-data/manage-buckets.html

AFX S3 bucket administration covers several routine tasks: editing bucket configuration after creation (capacity, protection, locking, and permissions), managing client access (users, access keys, and bucket policies), and inspecting the bucket for capacity/object counts. The page confirms S3 configuration and support in AFX is the same conceptual model as in classic ONTAP S3 — same protocol, same IAM/user model — but the access surface is through System Manager rather than the ONTAP CLI, which reflects AFX's storage-unit-oriented UX rather than the aggregate/volume hierarchy of classic ONTAP. For AI workloads that read object data from training jobs, this is the day-2 operations surface.

Create and configure an S3 bucket on an AFX storage system (ONTAP AFX docs)

Source: https://docs.netapp.com/us-en/ontap-afx/manage-data/create-configure-bucket.html

AFX exposes S3 object storage natively on each SVM: in System Manager, navigate to Storage → Buckets, provide the bucket name and capacity, optionally expand "More options" for data-protection, locking, and permission settings, then save. The S3 service on the SVM must already be configured before clients can reach the bucket — the bucket attach step assumes the SVM-side S3 server, users, and TLS are already in place. SnapMirror Cloud backs these buckets to the cloud, so capacity planning should consider the protection target as well as the active bucket size. This is the primary entry point for standing up an S3 data lake on AFX for AI/analytics workloads where data lands in object storage before being read by training pipelines.

Set up your AFX storage system ONTAP cluster (ONTAP AFX docs)

Source: https://docs.netapp.com/us-en/ontap-afx/install-setup/cluster-setup.html

After AFX hardware is installed, the ONTAP cluster setup proceeds in four sequential configuration phases: discover the cluster network, set the admin password, configure the cluster/controller IP addresses and subnet masks, and configure DNS/NIS plus optional NTP and cluster encryption. Initial setup is done from a laptop connected to the AFX management switch using System Manager, then cluster setup is completed with three more configuration areas. Core prerequisites include a unique IPv4 cluster-management address, network gateway, DNS domain and name servers, and NTP servers — items an AFX admin should gather before the install window.

Expand an AFX storage system cluster (ONTAP AFX docs)

Source: https://docs.netapp.com/us-en/ontap-afx/administer/expand-cluster.html

AFX clusters let you grow compute capacity independently of storage capacity, and the expansion is non-disruptive — performance scales linearly as Automated Topology Management (ATM) rebalances volumes across the new nodes. ATM uses Zero Copy Volume Move (ZCVM) to relocate volumes via metadata updates instead of copying data, which is the default volume-move technology on AFX. Coverage walks through the prerequisites (cluster admin credentials, SSH to the ONTAP CLI, an even number of new nodes per release-size limits), the troubleshooting scenarios you can hit while volumes are moving (volumes stuck because the cluster is already balanced, ATM seemingly idle because it polls every ~5 minutes and a rebalance can launch up to 40 minutes after the last one), and the CLI commands to monitor expansion. A real how-to for operators scaling AFX in production.

Display AFX storage system SVMs (ONTAP AFX docs)

Source: https://docs.netapp.com/us-en/ontap-afx/administer/display-svms.html

Short but useful reference for the basic AFX administrative workflow of viewing the storage virtual machines (data SVMs) configured in an AFX cluster — each SVM gives you an isolated environment for organizing data and presenting client access. The procedure is simple in System Manager: open Cluster, then Storage VMs, hover over the SVM you want to inspect, and the menu exposes primary admin actions (start/stop the SVM) plus a per-SVM detail pane covering overview, settings, replication, and file system. Cross-references include the related configure-SVM and ONTAP SVM concepts pages. A good companion piece for the create-configure-volume and create-configure-bucket how-tos already in the library.

How to modify the maxdir-size in ONTAP 9 (NetApp Knowledge Base)

Source: https://kb.netapp.com/on-prem/ontap/Ontap_OS/OS-KBs/How_to_modify_the_maxdir-size_in_ONTAP_9

Covers the ONTAP 9 volume-level `maxdir-size` knob (`vol options <vol> maxdir-size <bytes>` and the modern `volume modify -vserver <vs> -volume <vol> -max-dir-size <MiB>` form). The setting controls the maximum directory size in the WAFL inode file; hitting it is a classic cause of `No space left on device` errors on SMB/NFS shares even when `df` shows the volume still has free space. Useful when running legacy Windows file-server workloads with millions of files in a single directory — NetApp recommends against bumping the value above ~512 MB without TAC involvement. Applies to ONTAP 9.x (9.7+ preferred path via `volume modify`; older 9.x uses the `vol options` form).

AWS Storage Blog walk-through of attaching S3 Access Points to FSx for ONTAP file shares joined to AWS Managed Microsoft AD so that AI/ML services (Athena, SageMaker, EMR) can consume SMB/NFS file data through an S3-compatible interface with per-application credentials and policies. S3 Access Points provide per-application scoped endpoints with their own IAM policies, which removes the need to share a single wide-open S3 alias between teams — a key governance pattern for regulated AI workloads. The architecture diagram shows the FSx for ONTAP file system mounted by EC2-based AI clients while S3 Access Points present the same data through the S3 API, all fronted by the Active Directory join for identity. Reference for anyone building hybrid analytics where file-system and object-store access must coexist without copying data.

What is the expected I/O interruption time during ONTAP failover and its impact on VMware ESXi virtual machines? (NetApp Knowledge Base)

Source: https://kb.netapp.com/on-prem/ontap/Ontap_OS/OS-KBs/What_is_the_expected_I_O_interruption_time_during_storage_failover

NetApp's official sizing guidance for the I/O gap during ONTAP storage failover (SFO) when running VMware ESXi on NFS or block datastores. Confirms the I/O interruption is "typically limited to a few seconds up to approximately 15 seconds" — well under VMware's default NFS datastore timeout of 60s and the typical FC HBA timeout of 30s. Practical consequence: datastores stay mounted, VMs do not power off, in-flight I/O is briefly queued and resumes once the partner node is serving LIFs. Admins should expect short latency spikes inside guest OSes and brief application slowness but no fault tolerance events. Sets expectations correctly so the failover doesn't get escalated as a fault — useful for VMware/NetApp converged stack SREs.

What are the main failure cases that require cluster-level recovery in an ONTAP environment? (NetApp Knowledge Base)

Source: https://kb.netapp.com/on-prem/ontap/Ontap_OS/OS-KBs/What_are_the_main_failure_cases_that_require_cluster-level_recovery_in_an_ONTAP_environment

Definitive NetApp answer on when ONTAP needs cluster-level recovery (RDB + root aggregate restoration), as opposed to node-level or aggregate-level recovery. Two representative cases: (1) multiple simultaneous disk failures in aggr0 exceeding RAID-DP/RAID-TEC tolerance — typically more than three disks failing at once or a shelf-level power loss that takes root disks down. aggr0 holds the ONTAP OS image and the replicated database (RDB), so RDB quorum can't be re-established. (2) simultaneous power outage in both HA pair nodes causing a dirty shutdown that leaves RDB inconsistent. Cluster recovery is rare but disruptive — knowing the exact triggers helps admins plan dual-PSU, dual-feed, and battery-backed cache strategies for their root shelves.

ONTAP 9.x cluster-switch troubleshooting for Broadcom BES-53248 switches (the most common cluster-network switch in modern AFF deployments). Diagnoses the `SwitchUnreachable_Alert on CLUSTER_NAME (SWITCH_1 | SWITCH_2)` EMS event when `system switch ethernet show` returns `IsMonitored: false / Reason: IP address not reachable` and `network device-discovery show` shows the switch is still being CDP-discovered on the data port but the management IP no longer matches. The trigger: management-IP change (firmware upgrade, IP-reclaim, or operator error) without re-running ONTAP's switch-health monitor configuration. Shows expected output for both healthy and unhealthy states. Resolution: reconfigure the switch-health monitor (`system switch ethernet modify -switch-ip`) to the new IP and confirm reachability. Useful for any site that just did a switch firmware update.
