=head1 DESCRIPTION
|
|
|
|
This command is used to change xCAT object definitions which are stored in the xCAT database. The default is to replace any existing attribute value with the one specified on the command line. The command will also create a new definition if one doesn't exist.
|
|
|
|
This command also can be used to change the xCAT object name to a new name. Note: the site,monitoring types can NOT be supported.
|
|
|
|

|
|
|
=over 10
|
|
|
|
=item I<attr=val [attr=val ...]>
|
|
|
|
Specifies one or more "attribute equals value" pairs, separated by spaces. Attr=val pairs must be specified last on the command line. Use the help option to get a list of valid attributes for each object type.
|
|
|
|
=item B<-d|--dynamic>
|
|
|
|
Use the dynamic option to change dynamic node groups definition. This option must be used with -w option.
|
|
|
|
=item B<-h|--help>
|
|
|
|
Display usage message.
|
|
|
|
=item B<-m|--minus>
|
|
|
|
If the value of the attribute is a list then this option may be used to remove one or more items from the list.
|
|
|
|
=item B<-n> I<new-name>
|
|
|
|
Change the current object name to the new-name which is specified by the -n option.
|
|
The object of site, monitoring types cannot be supported.
|
|
Note: For the B<-n> option, only one node can be handled.
|
|
|
|
=item I<noderange>
|
|
|
|
A set of comma delimited node names and/or group names. (must be the first parameter) See the "noderange" man page for details on supported formats.
|
|
|
|
=item B<-o> I<object-names>
|
|
|
|
A set of comma delimited object names.
|
|
|
|
=item B<-p|--plus>
|
|
|
|
This option will add the specified values to the existing value of the attribute. It will create a comma-separated list of values.
|
|
|
|
=item B<-t> I<object-types>
|
|
|
|
A set of comma delimited object types. Use the help option to get a list of valid object types.
|
|
|
|
=item B<-V|--verbose>
|
|
|
|
Verbose mode.
|
|
|
|
=item B<-w> I<attr==val> B<-w> I<attr=~val> ...
|
|
|
|
Use one or multiple -w flags to specify the selection string that can be used to select objects. The operators ==, !=, =~ and !~ are available. Use the help option to get a list of valid attributes for each object type.
|
|
|
|
Operator descriptions:
|
|
== Select nodes where the attribute value is exactly this value.
|
|
!= Select nodes where the attribute value is not this specific value.
|
|
=~ Select nodes where the attribute value matches this regular expression.
|
|
!~ Select nodes where the attribute value does not match this regular expression.
|
|
|
|
Note: the operator !~ will be parsed by shell, if you want to use !~ in the selection string, use single quote instead. For example:-w 'mgt!~ipmi'.
|
|
|
|
=item B<-z|--stanza>
|
|
|
|
Indicates that the file being piped to the command is in stanza format. See the xcatstanzafile man page for details on using xCAT stanza files.
