This CucsLstorageConfigIssues bitmask enumeration flags any configuration problems UCS Manager detected while trying to create this specific LUN. A nonzero value here is the first thing an admin checks when a specific LUN in an otherwise-healthy storage profile fails to deploy, since it names the exact problem, such as insufficient disk space in the disk group, rather than a generic failure. A value flagging insufficient available capacity tells the admin the underlying disk group doesn't have room for this LUN's requested size.
