How Tivoli Storage Manager handles long user and group names
Tivoli® Storage Manager can handle user and group names that are up to 64 characters without any issues. However, names longer than 64 characters require special handling.
Restriction: Do not exceed the 64-character limit for
user and group names. Tivoli Storage
Manager shortens the name to fall within this limit by using the following
algorithm: Use the first 53 characters, append a forward slash (/),
and then use the numeric ID as a character string.
An error message is logged that contains both the long name and the resulting shortened string. For most functions, you do not need to be aware of the shortened name. The exceptions are:
- The set access command
- The fromowner option
- The users and groups (authorization) options
In each of these cases, when you need to enter a name, you either have to find the error message containing the transformation, or construct the name using the rule outlined here.
