Troubleshooting Server Consolidations 83
Trustee Rights Restored to Wrong User in Tree-to-Tree Copy
Problem: In a tree-to-tree consolidation scenario, it is possible to have users with the
same Common Name (CN) that exist in multiple contexts in the destination
tree (for example, jdoe.users.novell, jdoe.mktg.novell, and jdoe.sales.novell).
If you do not match up the user in the source tree with the desired user in the
destination tree, SMS automatically copies trustee rights to the first user match
it finds.
Action: Before running the consolidation, be sure to match up the users in the source
tree with the correct users in the destination tree.
Server Consolidation Performance Problems
Explanation: The performance of a project can be determined by looking at the success log
after a project completes. The success log gives the amount of time the project
took to complete and the amount of data copied.
There are several factors that determine the performance of the file copy. It is
also important that each server be updated to the latest Support Pack to ensure
you have the latest performance enhancements for SMS
TM
.
Possible Cause: Heavy traffic on the network.
Action: Speeds can be increased by connecting servers and the workstation to a
dedicated switch.
Possible Cause: A mismatch in duplexing among servers, switches, and the workstation.
Action: Make sure all hardware is set to either full duplex or half duplex. Setting all
hardware to half duplex might result in greater performance than full
duplexing.
Possible Cause: Virus scan software running on the source or destination servers.
Action: Turn off any virus scanning software on the source or destination servers to
increase the speed of the consolidation. Turn the virus scanning software back
on after the consolidation completes.
Possible Cause: An incorrect version of
smdr.nlm
is loaded on a NetWare server.
Action: At the NetWare server, unload
smdr.nlm
, then load the version of the
smdr.nlm
file that comes with the newest Support Pack.
Possible Cause: Small file sizes.
In general, the larger the file sizes, the better the performance. Copying a
single 500 MB file will be significantly faster than copying five thousand 100
KB files.
Possible Cause: Hardware configuration.
The performance of the Server Consolidation Utility varies according to the
environment. Using a 100 MB LAN, tests have measured speeds ranging from
3 to 15 GB per hour, with the most common speed being between 5 and 8 GB
per hour. You should check the performance of your LAN before copying very
large amounts of data.
