for eDirectory Users,” on page 149 .
3.9.7 Do Not Upgrade to eDirectory 8.8 Separately
If you are running OES 1 SP2, do not upgrade to eDirectory
TM
8.8 independently of upgrading to
OES 2 SP2.
For example, do not upgrade from eDirectory 8.7.3 to eDirectory 8.8.2 through the oes-edir88 patch
channel prior to upgrading to OES 2 SP2. Doing so causes configuration problems that the OES 2
SP2 install is not designed to handle.
3.9.8 Follow the Instructions for Your Chosen Platforms
Although installing OES 2 services on Linux or NetWare is a straightforward process, the
installation processes are platform-specific, requiring different sets of media and different
installation programs.
3.9.9 If You’ve Ever Had OES 1 Linux Servers with LUM and
NSS Installed
Having NSS volumes on OES servers requires certain system-level modifications, most of which are
automatic. For more information, see
Appendix I, “System User and Group Management in OES 2
SP2,” on page 257 .
However, as OES has evolved, some initially defined conventions regarding system Users have
needed adjustment. Be sure to read the information and follow the instructions in this section if your
network has ever included an OES 1 Linux server with both LUM and NSS installed.

NetStorage, XTier, and Their System Users
By default, certain OES services, such as NetStorage, rely on a background Novell service named
XTier.
To run on an OES server, XTier requires two system-created users (named
novlxsrvd
and
novlxregd
) and one system-created group that the users belong to (named
novlxtier
).
An NSS Complication
The two system users and their group are created on the local system when XTier is installed. For
example, they are created when you install NetStorage, and their respective UIDs and GID are used
to establish ownership of the service’s directories and files.
