SYSMULTI
----------------
A security label that is equivalent to all other defined security labels. It should be assigned only to servers that can properly isolate users and data based on security labels or UNIX directories that contain subdirectories and files at different security levels. This security label is usually not assigned to users, but there are some exceptions.
SYSMULTI gives you all SECLABELs.
The documentation recommends it be given to servers and not regular users, but you can if you want too.
Since you will only be using only one SECLABELs, there is no reason not to use it. Give your SECLABEL or SYSMULTI to access your datasets.
