I think what Torsten is saying is that the 2 new disks you added probably came from another server, and those 2 drives had been part of an array with ADG or something else that the E200i doesn't support.
The E200i will see those new drives and recognize the old array info that's on them, it's just warning you that you can't do anything with them.
If you're inserting used drives, do them with the power on (hot plug them) so the system sees just one at a time. If you insert a pair of drives that were part of an old array while the machine is turned off, when it turns on it'll read the info from them and assume you're migrating the array to a new system. Unless that's what you mean to do, try and avoid confusion.
Or delete the array info on any old drives from the original system before removing the drives, so they appear "new" even if you install them all at once somewhere else.
