NFS client products

IBM supports several NFS client products that provide Windows® computers with access to VOBs and dynamic views on Linux® or the UNIX® system.

If you use an NFS client product, you must complete these tasks:

Install it on each Windows client that will access VOBs or views on servers running Linux or the UNIX system.
Configure each installation to meet the special requirements of Rational® ClearCase®.

Note: An NFS client product supports access to Linux and UNIX file systems by a single Windows host. A Windows computer that uses an NFS client product to access VOBs on Linux or the UNIX system cannot provide other Windows computers with access to those VOBs.

For the complete list of supported products, see http://www.ibm.com/support/docview.wss?rs=984&uid=swg21239315.

Disabling automatic case conversion
Some NFS client products change the capitalization of file names by default, typically by converting to lowercase. This behavior can cause problems for the MVFS and cleartool commands so you must disable case conversion in the product you are using.
Setting default protection for an NFS client
If you plan to work in a shared view on a host running Linux or the UNIX system, configure your NFS client with a default protection that grants group write access. Without this permission, other developers cannot modify view-private files that you created.
Setting the correct logon name
To avoid VOB and view access permission problems, you must configure the NFS client to log on using user and group names on Linux and the UNIX system that match your Windows user and primary group names.
Hummingbird NFS Maestro: Disabling MS-DOS sharing
The Hummingbird NFS Maestro MS-DOS sharing option is incompatible with dynamic views.
DiskAccess: Supporting the Rational ClearCase server process user
DiskAccess must be configured to allow logins by the Rational ClearCase server process user. After you install DiskAccess on a computer and establish a DiskAccess log-on for yourself, configure an additional DiskAccess logon for the Rational ClearCase server process user account on Linux or the UNIX system.
Windows tags for VOBs on Linux or the UNIX system with remote storage pools
If a VOB on a host running Linux or the UNIX system includes remote storage pools , Windows hosts that use an NFS client product cannot access the VOB unless it has a tag in the Windows region that includes a split pool map, which provides a network path to each of the remote pools.
Automounting and NFS client software
Disable automounting when using any supported NFS client product. This allows the NFS client to use UNC names to access VOB and view storage on Linux or the UNIX system.
