=head1 DESCRIPTION
|
|
|
|
This command is used to remove xCAT object definitions that are stored in the xCAT database.
|
|
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 10
|
|
|
|
=item B<-a|--all>
|
|
|
|
Clear the whole xCAT database. A backup of the xCAT definitions should be saved before using this option. Once all the data is removed the xCAT daemon will no longer work. Most xCAT commands will fail.
|
|
In order to use xCAT commands again, you have two options. You can restore your database from your backup by switching to bypass mode, and running the restorexCATdb command.
|
|
You switch to bypass mode by setting the XCATBYPASS environmant variable. (ex. "export XCATBYPASS=yes")
|
|
A second option is to run xcatconfig -d. This will restore the initial setup of the database as when xCAT was initially installed.
|
|
You can then restart xcatd and run xCAT commands.
|
|
|
|
=item B<-f|--force>
|
|
|
|
Use this with the all option as an extra indicator that ALL definitions are to be removed.
|
|
|
|
=item B<-h|--help>
|
|
|
|
Display a usage message.
|
|
|
|
=item I<noderange>
|
|
|
|
