I found during my last code update with a VNX 5300 that after the upgrade to the latest code, all the wizards upper the File System Configuration were grayed out.

Troubleshooting looked like the code upgrade went bad, but in actuality, it was just the user permissions were corrupted on the sysadmin user.  To fix the issue, simply create a new user that has the administrator role assigned to them, log in with that user, and then delete and recreate the sysadmin user.

This fixes the issues and brings you back to using the sysadmin user.
