The B<xcatsetup> command is intended as a quick way to fill out the database for a cluster that has very regular
naming patterns. The only thing is done is fill in database attributes. If your cluster does not follow consistent
naming patterns. The only thing it does is fill in database attributes. If your cluster does not follow consistent
naming patterns, or has some other special configuration, you should define attribute values manually instead of using
B<xcatsetup>.
B<xcatsetup>. The cluster config file is meant to be an easy way to prime the database; it is not meant to be a
long living file that you update as the cluster changes. If you do want to run xcatsetup again at a later time,
because, for example, you added a lot of nodes, you should put the total list of nodes in the config file, not just
the new ones. This is because xcatsetup uses some regular expressions for groups (e.g. frame, cec, compute) that would
be calculated incorrectly if the config file told xcatsetup about only the new nodes.
Speaking of regular expressions, xcatsetup creates some pretty complicated regular expressions in the database.
These are useful because they keep most of the tables small, even for large clusters. But if you want to
tweak them, they may be hard to understand. If after running xcatsetup, you want to convert your database to
use individual rows for every node, you can do the following:
lsdef -z all >tmp.stanza
cat tmp.stanza | chdef -z
Note: currently the B<xcatsetup> command has only been implemented and tested for system p servers.
