Because of a lack of user equivalence for the root user, most CVU commands cannot be run as root to perform any remote node operations, except for the following:
However, using privilege delegation, you can specify the -method parameter and choose one of two methods (sudo or root) to enable the checks and run the fixup scripts that require root privileges to be performed on remote nodes. You will be prompted for a password but the password is used dynamically while the CVU commands run, rather than being stored on a storage device.
Specifying the -method parameter is advantageous in the context of fixup scripts. If you choose privilege delegation, then all the fixup scripts can be run at one time from the local node. If you do not choose privilege delegation, then you must log onto each relevant node as root and run the fixup script.
