|
|
B<nodech> - Changes nodes' attributes in the xCAT cluster database.
|
|
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<nodech> I<noderange> I<table.column=value> [I<...>]
|
|
|
|
B<nodech> {B<-d> | B<--delete>} I<noderange> I<table> [I<...>]
|
|
|
|
B<nodech> {B<-v> | B<--version>}

|
=head1 DESCRIPTION
|
|
|
|
The nodech command changes the specified attributes for the given nodes. Normally, the given
|
|
value will completely replace the current attribute value. But if ",=" is used instead of "=",
|
|
the specified value will be added to the attribute's comma separated list, if it is not already
|
|
there. If "^=" is used, the specified value will be removed from the attribute's comma separated list,
|
|
if it is there. You can also use "^=" and ",=" in the same command to essentially replace one item
|
|
in the list with another. (See the Examples section.)
|
|
|
|
See the B<xcatdb> man page for an overview of each table.
|
|
|
|
The nodech command also supports some short cut names as aliases to common attributes. See the
|
|
B<nodels> man page for details.
