Description: This object indicates previous OpCommand value. It will be updated after new OpCommand is set and delivered to upgrade process. 'none' if this object is read without performing any operation listed above, 'none' would be returned. Also 'none' would be returned for a read operation if a cleanup of the previous upgrade operation is completed either through the issue of 'done' command or the maximum timeout of 5 minutes is elapsed. Setting this object to 'none', agent would return a success without any upgrade operation being performed.

'done' if this object returns any value other than 'none', then setting this to 'done' would do the required cleanup of previous upgrade operation and make the system ready for any new upgrade operation. This is needed because the system maintains the status of the previous upgrade operation for a maximum time of 5 minutes before it does the cleanup. During this period no new upgrade operation is allowed.

'install' perform the required upgrade operation listed in ciuUpgradeTargetTable table. However the upgrade operation for a module would not be done if the current running image and the image to be upgraded given as an input through the ciuImageLocInputTable are the same.

'check' check the version compatibility for the given set of image files against the current system configuration.
