-=head2 node_status
-
- Parameters : $computer_node_name (optional)
- Returns : string
- Description : Checks the status of an xCAT-provisioned machine. If no
- arguments are supplied, the node and image for the current
- reservation will be used. The return value will be one of the
- following:
-
- READY
- If $self->data contains image information:
- - The computer is responding to SSH
- - nodetype.profile is set to the image defined in $self->data
- - Current image retrieved from computer's OS matches $self->data
- If $self->data does not contain image:
- - The computer is responding to SSH
- - Current image retrieved from computer's OS matches
- nodetype.profile
-
- RELOAD
- - Only returned if $self->data contains image information
- - Either nodetype.profile does not match $self->data or the
- current image retrieved from computer's OS does not match
- $self->data
-
- UNRESPONSIVE
- - The computer is not responding to SSH
-
- INCONSISTENT
- - nodetype.profile does not match the current image retrieved
- from computer's OS
