Introduction to Validating xCAT Configuration
This document describes a series of steps to validate xCAT configuration prior to configuring Moab to manage hardware via xCAT. It is assumed the reader is familiar with xCAT and the xCAT configuration on the target site. This document does not provide xCAT configuration documentation or troubleshooting information; please refer to the xCAT documentation for such information.
Verifying Node List
Verify that all nodes that Moab will manage are known to xCAT with the xCAT nodels command. Ensure that all expected (and no unexpected) nodes are listed. You may find it useful to create new group names to identify Moab managed nodes.
Reporting Node Status
Verify that all nodes report their status correctly using the xCAT nodestat command. Ensure that all nodes show the correct status (sshd, installing, noping, and so forth); there should not be any timeouts or error messages.
Verifying Hardware Management Configuration
Verify that all nodes that Moab will manage have hardware management interfaces correctly configured using the xCAT nodels and rpower commands. After each of the rpower commands, verify the requested state was achieved with rpower stat.
Verifying Provisioning Images
Verify that all operating system images that Moab uses are configured correctly in xCAT. For stateful images, test that all combinations of operating system, architecture, and profile install correctly.
For stateless images, test that nodes are able to network boot the images.
Verifying VM Migration
If you use VM migration, verify that xCAT can successfully perform migrations using the rmigrate command.
