  • Page 11: Failover

    Failover The XP family of disk arrays supports many standard software products that provide host, application, or I/O path failover and management. TruCluster is one of the supported applications. CAUTION: Tru64 verson 5 fully supports dynamic load balancing and failover when multiple HBAs are connected to the same LUN.

  • 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 14: Setting The Host Mode For The Disk Array Ports

    Setting the host mode for the disk array ports After the disk array is installed, you must set the host mode for each disk array port to match the host OS. Set the host mode using LUN Manager in Remote Web Console XP (shown), Command View XP, or Command View XP Advanced Edition.
  • Page 15 For the XP1024/XP128 arrays, the host mode can also be set at the port information window in Command View XP AE. Disk Array XP operating system configuration guide: Tru64 UNIX...

  • Page 16: 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. 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.

  • 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 table and figures. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide on the www.hp.com web site.

  • 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: Configuring System Files

    Configuring system files Configure the Tru64 system to recognize the HBA as explained in the Tru64 Installation Guide or New Hardware Delivery (NHD) kit. This usually consists of booting genvmunix and executing doconfig (as explained in the Installation Guide). This can also sometimes be done by editing the system kernel configuration file as explained below.

  • Page 20: Setting Up Clustering And Fabric Zoning

    Setting up 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 21: Setting Up Fabric Zoning And Lun Security For Multiple Operating Systems

    Setting up 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 22: 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 23 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 LUN Configuration and Security Manager User’s Guide or Command View XP Advanced Edition Device Manager Web Client User’s Guide. Note the LUNS and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration.

    Verifying host recognition of disk array devices Use the scu show edt command at the UNIX prompt to see the list of new disk array devices. The device files are created automatically in Tru64 UNIX during system startup. Device files are created for each logical unit. Verify the character-type device files have been automatically created: Example —...

  • Page 25: Configure Disk Devices

    Configure disk devices Disks in the disk array are configured using the same procedure for configuring any new disk on the host. This includes the following procedures: 1. Writing the partition labels 2. Creating the file systems 3. Creating mount directories 4.

  • Page 26: Writing The Partition Labels

    Writing the partition labels Use the disklabel command to label the partition for each logical unit. Partition c specifies the entire area in the logical unit. Check that no errors are found in the partition settings after the labeling. You can edit the disk partition size using the disklabel command with option –e. When the disklabel –e command is executed, the vi editor for the environment in which you are working starts up.

  • Page 27: Creating The File Systems

    Creating the file systems Create a file system for each new OPEN-x device. Optionally, you can create and use an advanced file system (AdvFS) to overcome the size and speed limitations of the file system. If you are not sure which file system is right for your setup, contact HP customer support.

  • Page 28: Creating Mount Directories

    Creating mount directories Create a mount directory for each device. Assign each mount directory a unique name that identifies the device being mounted. Create a mount directory. /mount_directory_name # mkdir Example To create a mount directory for LUN 2 (partition c) on the disk array, enter: # mkdir /HP5700_LU2c Verify the new mount directory.

  • Page 29: Mounting The File Systems

    Mounting the file systems After the file systems and mount directories have been created, you can mount the file system for each new device. To mount a Tru64 file system: Mount device: device_file_name mount_directory # mount Example To mount device rz12c with mount directory name HP5700_LU2c, enter: # mount /dev/rz12c /HP5700_LU2c Example —...

  • Page 34: Checking Path Failover

    Checking path failover The disk array supports Tru64 path failover (Tru64 v5 only). You can connect multiple HBAs to the disk array with shared LUNs. Confirm the existence of multiple paths for devices as follows: Type hwmgr -view device to obtain the HWID for the device. Type hwmgr -show scsi -full -id HWID to confirm the status of paths to the device.
