3PAR support engineers use "touch files" like that to enable work arounds or diagnostic features on a temporary basis. The intent is they should eventually be removed by support once the issue was resolved.
You should contact HPe support, but I don't recommend calling unless its an emergency. If you're not setup with web access to support, its worth the time to get it setup. If you have your service processor set to phone home, you can open your case online... and support will fix it remotely.
You will need to create an HPe passport account, and link your SN#, and contracts (SAID numbers) here:
