  • Page 11: Snmp Configuration

    SNMP configuration The XP family of disk arrays supports standard Simple Network Management Protocol (SNMP) for remotely managing the disk array. The SNMP agent on the service processor (SVP) performs error-reporting operations requested by the SNMP manager. SNMP properties are usually set from the SVP but they can also be set remotely using Remote Web Console XP, Command View XP, or Command View XP Advanced Edition.

  • Page 12: Installation Procedures

    Installation procedures Perform these actions to install and configure the disk array: 1. Install and configure the disk array • Setting the host mode for the disk array ports Setting the System Option Modes • • Configuring the Fibre Channel ports 2.

  • Page 13: Install And Configure The Disk Array

    Install and configure the disk array The HP service representative performs these tasks: • Assembling hardware and installing software • Loading the microcode updates • Installing and formatting devices After these tasks are finished, you will use Remote Web Console, Command View, Command View XP Advanced Edition, or LUN Configuration and Security Manager to complete the remaining tasks listed below.

  • Page 15: Setting The System Option Modes

    Setting the System Option Modes The HP service representative sets the System Option Mode(s) based on the operating system and software configuration of the host. Description and Usage Mode Level HA Software None Optional ON: Response to the Inquiry command is changed, and the volume can be used from VeritasNetBackUP in heterogeneous OS configuration, such as HP-UX.

  • Page 16: Configuring The Fibre Channel Ports

    Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports by using Remote Web Console (shown), Command View, or Command View XP AE. Select the settings for each port based on your storage area network topology. Use switch zoning if you connect different types of hosts to the array through the same switch.

  • Page 17: Fabric And Connection Parameter Settings

    Fabric and connection parameter settings Set each array port to FABRIC ON or OFF with connections of POINT-TO-POINT or FC-AL as shown in the following figure and table. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide on the http://www.hp.com website.

  • Page 18: Install And Configure The Host

    Install and configure the host This section explains how to install and configure the host and host bus adapters (HBAs) that connect the host to the disk array. Loading the OS and software Follow the manufacturer’s instructions to load the operating system and software onto the host.

  • Page 19: To Check The Firmware Level

    To check the firmware level: The HBA should have the proper version of firmware installed. Use the lsdev command to display the device object. Example # lsdev -Cc adapter Use the lscfg command to display the firmware level. Example # lscgfg -vl fcsX fcsX is the fiber device object (typically fcs0).

Wait for status to change from RUNNING to OK. Check installation summary result (SUCCESS). Press F10. Use the smit devinst command to configure the devices. Installation...

  • Page 21: Clustering And Fabric Zoning

    Clustering and fabric zoning If you plan to use clustering, install and configure the clustering software on the servers. Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node. Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster environment with three clusters, each containing two nodes.

  • Page 22: Fabric Zoning And Lun Security For Multiple Operating Systems

    Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters of various operating systems to the same switch and fabric using appropriate zoning and LUN security as follows: • Storage port zones may overlap if more than one operating system needs to share an array port.

  • Page 23: Defining The Paths

    Defining the paths Use Remote Web Console (shown), Command View, or Command View XP AE to define paths (LUNs) between hosts and volumes in the disk array. This process is also called “LUN mapping.” In Remote Web Console and Command View, LUN mapping includes: •...

If the disk array LUNs are defined after the IBM system is powered on, issue a cfgmgr command to recognize the new devices.
