Introductory Notes

This section contains information about various mpadmin topics that you will find useful when reading about cluster administration tasks in later sections.

Naming Partitions and Custom Attributes

You can assign names to partitions and to custom attributes. Custom attributes are attributes that are not part of the default CRE database; they are discussed in "Setting Custom Attributes".

Names must start with a letter and are case sensitive. The following characters can be used:

ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz 0123456789-_.

The only limit to name length is the limit imposed by Solaris on host names--it is ordinarily set at 256 characters.

Do not begin an attribute name with the characters mp_. This starting sequence is reserved by the CRE.

Separate Name Spaces

Nodes and partitions have separate name spaces. Thus, you can have a partition named Parallel that contains a node named Parallel.
