Review MSA installation best practices MSA installation best practices fall into one of three categories: planning, installation, and ongoing. Planning • Before installing your MSA (and periodically afterwards), go to the MSA1500 website to confirm your installation plans and read current information about the device: http://www.hp.com/go/msa1500cs. • Prepare for the installation by reviewing the Configuration Installation and Overview poster. This poster will help you gather all of the items required for the installation. • Record information about your system on the provided worksheets. System information is needed when configuring the storage, entering connection information, setting up multipathing, and for future configuration changes and reference purposes. Use the "Configuration Planning Worksheet" on the Configuration Installation and Overview poster or "Worksheets" on page 107 of this guide. Installation • Install your MSA in the sequence listed in this guide. Several installation and configuration steps include dependencies and if you deviate from the listed sequence, you may have to uninstall and then reinstall your MSA. Difficulties that you encounter by not following the directions in this guide may result in lost time and lost revenue while troubleshooting the issues. For example, in a Windows environment, when you power up the server after installing the HBA for the MSA, Windows displays a "New Hardware Found" message and prompts to install an HBA driver. You must cancel out of this window or Windows will install an HBA driver that is unsupported for use with the MSA. • When installing the MSA, consider redundancies of power, storage, and data paths to ensure uninterrupted access to the storage. • To provide redundant power, plug the two power supplies on the MSA into separate Uninterruptable Power Supplies (UPSs) on separate sources of power. If you have only one UPS, maintain separate power paths by plugging one MSA power supply to the UPS on one power source and plug the other MSA power supply to a separate power source. • To provide redundant storage, configure your Logical Units (LUNs) using fault-tolerant Redundant Array of Independent Disks (RAID) levels and striping methods. Stripe the LUNs vertically across separate storage enclosures on different SCSI buses, including drives from each bus. • To provide redundant data paths, you must include two separate and isolated Fibre Channel fabrics and the associated hardware and software components in the configuration. You must include two MSA controllers, two Fibre Channel interconnect devices (switches/fabrics), and a minimum of two HBAs per server. In addition, multipathing software must be installed on each server with access to the MSA. HP StorageWorks 1500 Modular Smart Array installation guide 21

Review MSA installation best practices

MSA installation best practices fall into one of three categories: planning, installation, and ongoing.

Planning

•

Before installing your MSA (and periodically afterwards), go to the MSA1500 website to confirm

your installation plans and read current information about the device:

http://www.hp.com/go/msa1500cs

•

Prepare for the installation by reviewing the Configuration Installation and Overview poster. This

poster will help you gather all of the items required for the installation.

•

Record information about your system on the provided worksheets. System information is needed

when configuring the storage, entering connection information, setting up multipathing, and for

future configuration changes and reference purposes. Use the “Configuration Planning

Worksheet” on the Configuration Installation and Overview poster or

page 107 of this guide.

Installation

•

Install your MSA in the sequence listed in this guide. Several installation and configuration steps

include dependencies and if you deviate from the listed sequence, you may have to uninstall and

then reinstall your MSA. Difficulties that you encounter by not following the directions in this

guide may result in lost time and lost revenue while troubleshooting the issues. For example, in a

Windows environment, when you power up the server after installing the HBA for the MSA,

Windows displays a “New Hardware Found” message and prompts to install an HBA driver.

You must cancel out of this window or Windows will install an HBA driver that is unsupported for

use with the MSA.

•

When installing the MSA, consider redundancies of power, storage, and data paths to ensure

uninterrupted access to the storage.

•

To provide redundant power, plug the two power supplies on the MSA into separate

Uninterruptable Power Supplies (UPSs) on separate sources of power. If you have only one

UPS, maintain separate power paths by plugging one MSA power supply to the UPS on one

power source and plug the other MSA power supply to a separate power source.

•

To provide redundant storage, configure your Logical Units (LUNs) using fault-tolerant

Redundant Array of Independent Disks (RAID) levels and striping methods. Stripe the LUNs

vertically across separate storage enclosures on different SCSI buses, including drives from

each bus.

•

To provide redundant data paths, you must include two separate and isolated Fibre Channel

fabrics and the associated hardware and software components in the configuration. You must

include two MSA controllers, two Fibre Channel interconnect devices (switches/fabrics), and

a minimum of two HBAs per server. In addition, multipathing software must be installed on

each server with access to the MSA.
