In CA Common Services r14.0 and above, a feature is available which allows an LMP Key to be bypassed. To do this, you can add the DELETE or REMOVE keyword after the valid LMP Key in the KEYS member and load the keys again with the following command:
The DELETE and REMOVE Parms are synonymous, and do not actually delete the LMP Key from storage, but cause it to be bypassed. Details can be found on the CA Common Services Product Execution Key Control Statements DocOps page. Otherwise, the LMP Key can be removed from the Keys member and an IPL done.
