Configuring the NS2000 for DevOps Code ClearCase

About this task

To configure the NS2000 for use by DevOps Code ClearCase®:

Procedure

  1. Create a file system if necessary.
    You may use an existing file system or create a new one specifically for use by DevOps Code ClearCase.
  2. Create partitions.
    For ease of administration, using virtual partitions on the NS2000 to hold DevOps Code ClearCase data is recommended. The remaining steps in this section assume you are using a virtual partition named /dev/axvp/fspnvpx, where n is the number of the file-system partition and x is the virtual partition number.
  3. Create a file system mountpoint.
    Log in to the NS2000 as root. Run the following command to create a mountpoint for the virtual file system you created in Step 2:

    mkdir /vobstg

  4. Mount the virtual file system.
    Run the following command to mount the virtual file system you created in Step 2 at the mountpoint you created in Step 3:

    mount -F lofs /dev/axvp/fspnvpx /vobstg

    To ensure that a virtual file system is mounted at boot time, create an entry for it in /usr/AXbase/etc/lfstab.
  5. Enable read/write access for the DevOps Code ClearCase UNIX™ server process user account.
    The Administrator's Guide describes this account, which provides a user identity on the UNIX system and Linux™ to which the Windows™ domain account for the DevOps Code ClearCase server process user can be mapped. All volumes used for VOB or view storage must be configured with read/write (rw) access for this account.
  6. Make the file system accessible.
    Volumes that are accessed only by computers running the UNIX system or Linux must be shared by using the NetOS share command. Volumes that are accessed only by Windows computers must be shared by using the NetOS net share command. Volumes that must be accessed by both types of computers must be made accessible using both commands. The following command makes the file system mounted at /vobstg accessible to NFS clients:

    share -F NFS /vobstg

  7. Disable oplocks.
    Opportunistic locking (CIFS oplocks) is enabled by default on the NS2000. You must disable oplocks by setting the NS2000 registry key: HKLM\SYSTEM\CurrentControlSet\Services\AdvancedServer\FileServiceParameters\UseOplocks to a value of 0 using the NetOS regconfig command or the Windows registry editor. To use the Windows registry editor to edit the registry on the NS2000, click Registry > Select Computer and type the name of the NS2000 in the Select Computer window.
