    • LUSE (expanded) CVS devices (OPEN-x*n CVS): LUSE CVS combines CVS devices to create an expanded device. This is done by first creating CVS custom-sized devices and then using LUSE to combine from 2 to 36 CVS devices. For example, if three OPEN-9 CVS volumes are combined to create an expanded device, this device is designated as OPEN-9*3-CVS.

  • Page 13: 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 14: Setting The System Option Modes

    For the XP1024/XP128 arrays, the host mode can also be set at the port information window in Command View XP AE. 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.

  • Page 16: 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 Fabric and Connection parameter settings...

    Connection Parameter Fabric Parameter Provides FC-AL Not supported FC-AL AL-port (private arbitrated loop; direct connect without a SAN) Point-to-Point N-port (SAN fabric port) Point-to-Point Not supported 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.

  • Page 18: Installing And Configuring The Hbas

    Installing and configuring the HBAs Install and configure the host bus adapters using the HBA manufacturer's instructions. On Linux systems, the disk array only supports QLogic and Emulex adapters. Contact your HP service representative for the latest information about supported HBAs. Clustering and fabric zoning If you plan to use clustering, install and configure the clustering software on the servers.

  • Page 19: 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 20: 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 21: Verifying New Device Recognition

    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.

  • Page 23: Configure Disk Array Devices

    Configure disk array 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. Partitioning the devices 2. Creating the file systems 3. Creating the mount directories 4.

  • Page 24: Creating File Systems With Ext2

    Creating file systems with ext2 Enter mkfs –t ext2 /dev/device_name. Example # mkfs –t ext2 /dev/sdd Repeat step 1 for each device on the disk array. Creating the mount directories Create mount directories using the mkdir command. Choose names for the mount directories which identify both the logical volume and partition.

  • Page 25: Creating The Mount Table

    Repeat step 1 for each device on the disk array. Creating the mount table Add the new devices to the /etc/fstab file to specify the automount parameters for each device. Edit the /etc/fstab file to add one line for each device to be automounted. Each line of the file contains: (A) device name, (B) mount point, (C) file system type (“ext2”), (D) mount options (“defaults”), (E) enhance parameter (“1”), and (F) fsck pass 2.
