    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: Fibre Address

    Fibre Address In fabric environments, the port addresses are assigned automatically. In arbitrated loop environments, set the port addresses by selecting a unique arbitrated loop physical address (AL-PA) or loop ID for each port. For specific values, refer to the HP StorageWorks LUN Configuration and Security Manager XP User Guide applicable to your array.

  • 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: 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 20: 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 21: Connect The Disk Array

    Connect the disk array The HP service representative connects the disk array to the host by: Verifying operational status of the disk array channel adapters, LDEVs, and paths. Connecting the Fibre Channel cables between the disk array and the fabric switch or host.
  • Page 22 In Command View XP AE, LUN mapping includes: • Configuring ports • Creating storage groups • Mapping volumes and WWN/host access permissions to the storage groups For details see the LUN Configuration and Security Manager User’s Guide or the Command View XP Advanced Edition Device Manager Web Client User’s Guide.

  • Page 29: Creating The Device Files

    Creating the device files If the device files were not created automatically when the system was restarted, use the insf –e command in the /dev directory to create the device files. After this command is executed, repeat the procedures in the previous section Verifying device recognition verify new device recognition and the device files and driver.
  • Page 30 Enter the major numbers for the device drivers into the table. You should now have all required device and driver information in the table. Create the device files for all disk array devices (SCSI disk and multiplatform devices) using the mknod command. Create the block-type device files in the /dev/dsk directory and the character-type device files in the /dev/rdsk directory.

  • Page 31: Creating The Physical Volumes

    Creating the physical volumes A physical volume must be created for each new SCSI disk device. To create the physical volumes: Use the pvcreate command to create the physical volumes with the character-type device file as the argument. Specify the /dev/rdsk directory. Example # pvcreate /dev/rdsk/c6t0d0 Physical volume "/dev/rdsk/c6t0d0"...

  • Page 32: Creating New Volume Groups

    Creating new volume groups You must create new volume groups for the new physical volumes. If desired, you can also add any of the volumes on the disk array to existing volume groups using the vgextend command. The physical volumes that make up one volume group can be located either in the same disk array or in other disk arrays.
  • Page 33 Create the volume group. To allocate more than one physical volume to the new volume group, add the other physical volumes, separated by a space. Example # vgcreate /dev/vg06 /dev/dsk/c6t0d0 Volume group "/dev/vg06" has been successfully created. Volume group configuration for /dev/vg06 has been saved in /etc/1vmconf/vg06.conf.
