To configure the NS2000 for use by Rational® ClearCase®:
Create a file system if necessary. You may use an existing
file system or create a new one specifically for use by Rational ClearCase.
Create partitions. For ease of administration,
using virtual partitions on the NS2000 to hold Rational 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.
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
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.
Enable read/write access for the Rational 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 Rational 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.
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
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.
