Object naming

All objects in a system have names that are user-defined or system-generated.

Choose a meaningful name when you create an object. If you do not choose a name for the object, the system generates one for you. A well-chosen name serves not only as a label for an object, but also as a tool for tracking and managing the object. Choosing a meaningful name is important if you decide to use configuration backup and restore.

Naming rules

The following rules apply when you choose a name for an object:
  • Do not start names by using an underscore even though it is possible. The use of the underscore as the first character of a name is a reserved naming convention that is used by the system configuration restore process.
  • The first character of a file volume name cannot be numeric.
  • The name can be a maximum of 63 characters, with one exception. The lsfabric command displays long object names that are truncated to 15 characters for nodes and systems.
  • Valid characters are uppercase letters (A - Z), lowercase letters (a - z), digits (0 - 9), underscore (_), period (.), hyphen (-), and space.
  • Names must not begin or end with a space.
  • Object names must be unique within the object type. For example, a volume and an MDisk can each be called ABC; however, two volumes cannot be called ABC.
  • The default object name is valid (object prefix with an integer).
  • Objects can be renamed to their current names.
