Before setting up your virtual environment, verify that your planned configuration will meet the system requirements, licensing and other considerations for installation with Storage Foundation and High Availability (SFHA) Solutions products.

Licensing: Storage Foundation or Storage Foundation Cluster File System High Availability in an LPAR may be licensed either by licensing the entire server (for an unlimited number of LPARs) or licensing the maximum number of processors cores assigned to that LPAR.
IBM Power virtualization requirements: See IBM documentation.
Veritas product requirements: See Table: Veritas product requirements
Release Notes: Each Veritas product contains last minute news and important details for each product, including updates to system requirements and supported software. Review the Release Notes for the latest information before you start installing the product.

Installation, patching, and configuration requirements:	Veritas strongly recommends that you use Veritas InfoScale products 7.3 with the latest patches. No other configuration is required. Refer to the following website for the latest patches for Storage Foundation 7.3 on AIX: https://sort.veritas.com/checklist/install/

To use VCS to manage LPARs as virtual machines, the following requirements must be met.

Table: VCS system requirements for the LPAR-supported configurations

VCS requirement

Description

VCS version

6.0 and later

Supported OS version in LPARs

AIX 6.1 TL 5 and above.

AIX 7.1 and above.

Supported VIOS version

2.1.3.10-FP-23 and above

Supported HMC version

7.2.0.0

Note:

Best practice: all the physical servers that are part of a cluster are managed by the same HMC.

Supported hardware

Power 5, 6, and 7

Table: N_Port ID Virtualization (NPIV) requirements

NPIV requirement	Description
NPIV support	Included with PowerVM Express, Standard, and Enterprise Edition and supports AIX 6.1 and AIX 7.1.
VIO requirements	NPIV requires a minimum of Power6 systems, VIOS 2.1, and 8GB HBA adapters. NPIV also requires NPIV aware switches. The end storage devices need not be NPIV aware.
Hardware requirements	NPIV requires extended functionality on the HBA. Currently IBM sells this as an 8GB HBA, part number XXXXX. The SAN Switch ports must also support NPIV as well, Brocade and Cisco make products that provide this functionality.
Information for NPIV and how to configure an IBM VIO environment	See IBM documentation.

Installation, patching, and configuration requirements for NPIV support:

No patches are needed at the time of release. No other configuration is required.
Using 7.3 products with the latest patches when they become available is strongly recommended.
For current information on patches, see:
