Data Guard question

I just started playing around with Data Guard for the first time this
week. For reasons I won't go into that MAY be related to age, I am
using DGMGRL instead of OEM to manage the broker. The primary is called
daffy and the physical standby is called daffysby. It seems OK in that
I can see transactions get applied to daffysby but DGMGRL gives me a
warning. It has to do with missing standby redo logs (SRLs) on the
primary. I have SRLs in both the primary and the standby. The High
Availability Best Practice guide alludes to putting SRLs in the flash
recovery area (which I have not done at this point) but I am not
convinced that is the issue. I've searched Metalink and the web for
"missing SRLs" with not a whole lot of luck. All the redo logs are the
same size.
My question is does anyone know to get rid of this warning? Can it be
safely ignored? I would think not.
Any/all pointers/links/advice welcome. This is a test environment so I
can try anything.
Thanks,

(hope this formats ok)
