SRM 5.0 U2/Device cannot be matched to a remote peer device

In our environment, I installed VC 5.02 with SRM 5.02 on the same server. And installed IBM SRA (05.00.3550.0021) in vCenter server on Production site and DR site.

After I installed IBM SRA, I have configured to add Array Manger to add DS5020 SAN storage in Production Site and DR Site.

Then I enabled array pair in Production Site. SRM will automatically enable corresponding array pair (remote array in DR site) as well.

After a while, the status of Array Pair become "enable" in  Production site and DR site.

SRM can detect all remote pairs (Remote mirror Copy relationship defined bewteen LUN in Production site and LUN in DR site).

But it also show the error "Device cannot be matched to a remote peer device" for non-array pair. How to solve this error? How to ignore SRM to scan these devices?
