>From the 5.1 Unix client manual, Summary of Changes, Technical Changes for
version 5.1.5

Support for a globally unique identifier (GUID)
The globally unique identifier (GUID) associates a client node with a host
system. When you install the Tivoli software, the tivguid program is run to
generate a GUID which is stored in the /etc/tivoli directory on a UNIX
system. The GUID for a client node on the server can change if the host
system machine is corrupted, if the file entry is lost, or if a user uses
the
same node name from different host systems. You can perform the
following functions from the command line:
v Create a new GUID
v View the current GUID
v Write a specific value
v Create another GUID even if one exists.
See "Associating your client node with a host system" on page 36 for more
information.

I don't know what it is actually used for.  I can tell you that, the 5.1.5.2
client on AIX updates the new GUID column in the NODES table.  If I change
the GUID on the client, then if I do something as small as a "dsmc query
filespace" it updates the GUID column in the NODES table.  That's about all
I know about it.

Hope this helps.

Subject: GUID in TSM


Anyone have any experience with or know anything about the GUID stuff in the
version 5 clients?

According to the docs, it's a pre-req for installation, however,
installations work and the client *seems* to function without it.

Not much in the way of information about what it is or what it does, either.
