    how can I create lun’s in my hitachi 9990USPV hard drive

    I have recently bought Hitachi 9990USPV and I would love to know from you some information about it. How should I create a new lun(Logical unit number) and gradually map it to a host?? And how should I add new host??? Can anyone help me regarding this. Any help will be appreciated. Thanks in advance.

    To create a LUN you should do the following process:

    • Connect to storage navigator
    • Select the array you think which is suitable and Login
    • After you are logged in. click the pen in the top right hand corner and change the modify mode
    • Click on the LUSE/VLL icon and Click on the VLL tab
    • Gradually expand the box number you want to create LUN
    • Expand the parity group you want to create the LDEV
    • Select the VDEV and right click on free space and Select install CV
    • create a new LDEV/LDEV by following the wizard
    • If your connected to an open system then emulation type will be Open-V

    After creating and formatting the LDEV, you should map it using LUN manager as follows:

    • Click on the LUN manager ICON
    • Eventually expand a port to bring the LUN down
    • Right click on the port and create a host group and set Host type
    • Select the LUN you want to map through the LUN window
    • Select and add the H-LUN number in the LUN path, then click ok

    Dude the process is different. You should create DP-VOL in the form of V-VOL in the pool. You should refer to dynamic provisioning user guide to enhance your information about this process. As per your doubt. An LDEV is a collectiong of logical blocks in a VDEV and an VDEV is a virtual created on top of a PDEV.
