1 About This Document

This chapter contains the following parts:

• Purpose

• Target groups

• Prerequisites

• Typographic conventions

1.1 Purpose

The document describes the installation & configuration of the 2540 storagearrays so that they will be compatible with the OSS-RC software installation.

This document was initially verified using 2540 array firmware revision06.70.54.11 and CAM software version 6.2.0.13. Beware that newer revisionof CAM (including firmware) may be available on the software baseline, ormay be required by new arrays, meaning that the verified revisions are justexamples and not recommendations.

Note: Please note that the menu diagrams used in this document do notreflect the installation/configuration exactly, but are provided as ameans of demonstrating where the menu options exist.

1.2 Target Groups

This document is intended for the installers of OSS-RC product, whereby thestorage used on the server are 2540 storage arrays.

1.3 Prerequisites

It is assumed that the user of this document:

• Has confirmed that the IP address has been set up on the 2540 storagearray

• Is familiar with the 2540 storage array and its concept of logical drivesand volumes

Installation

3 Installation

3.1 Connect 2540 to OSS-RC server

Connect from the Host Bus Adapter card on the OSS-RC server to the first PCHost connection on the 2540 array.

Figure 1 Installation of Host Bus Adapter

3.2 Get WWN of the Fibre Channel Host Bus Adaptors

In certain HW configuration scenarios, such as a HA configuration or wherethe arrays are connected to the server via a Fibre Channel switch, it may benecessary to determine the WWN of the HBA cards.

These numbers will be needed to correctly create the initiators described laterin this document.

For each host connect to the arrays, do the following

1. Boot the server into single user mode from cdrom or network boot image

2. Record the Port WWN(s) associated with each server connected to thearray. This can be done using the following commandsluxadm probe to list the Logical Paths

53/1531-AOM 901 046 Uen A4 | 2010-08-12


luxadm display <logical_path> to print the Host controller portWWN

There is a list_port_wwn.sh script provided in the appendices that will alsoprint out the Port WWN(s).

3. Halt the server once more. If the platform is an sparc platform, then bringit to the 'ok>' prompt

3.3 Install CAM Software

Install the CAM software on a local machine by following the procedure outlinedin the Common Array Manager Installation Instruction document [ref 3]

Note: This document was tested on a machine using the Solaris 10 OS onsparc architecture and with CAM software version 6.2.0.13. The useralso had root access to the machine.

3.4 Open CAM Software

Open a web browser and go to the following address:

https://localhost:6789

Log into the CAM software

3.9 Create Array Host

For each host that will be connected to the array (HA config will have more thanone), it is necessary to create an Array Host identifier that identifies each of thehost(s) that the storage array is connected to. The hostname of the individualserver is a good choice.

On the left hand pane, expand the array name and then expand the PhysicalDevices link. Select the Hosts link and then select New in the right hand pane.

Enter the host name and press OK.

1. For the Initiator Name enter hostname that was used in the Create ArrayHost section.

2. Select Discovered Unique Identifier to show the discovered Port WWNsof any connected HBA cards. If there is no WWN discovered, then pleaseensure that the arrays are connected correctly to the server. There shouldbe a Fibre Channel Link light on.

If the server is a Sparc platform then it is also recommended to perform areset-all and a probe-scsi-all at the ok prompt.

3. Select the HBA adaptor to be associated with this initiator. This shouldcorrespond to one of the HBA WWN's noted earlier in this procedure.

4. For the Host Type select Solaris (with Veritas DMP or other)

5. Select Existing Host and select the Host name defined in the previoussection

6. Select Next and then Finish to create the initiator.
