How do I uninstall a hotfix

I refered to this document http://www.symantec.com/business/support/index?page=content&id=TECH73443 but when I run the vxhf.exe /uninstall I get a error. When I check /help that command isnt there.

Usage:
-------
VxHFBatchInstaller.exe /CP:<CPName> [/Exclude:<HF1.exe>,<HF2.exe>...] [/PreInstallScript:<PreInstallScript.pl>] [ /silent [/forcerestart] ]
VxHFBatchInstaller.exe /list
VxHFBatchInstaller.exe /help
Where CP represents Cumulative Patch.

C:\Program Files (x86)\Common Files\Veritas Shared\WxRTPrivates\CP13_SFWHA_51SP2
>vxhfbatchinstaller.exe /uninstall:HF50
The syntax of the command is incorrect.
