ASM DG with external redundancy - Metric question

in Database - RAC/Scalability (MOSC) 2 commentsAnswered

Hi,
we have LUNs in our Diskgroups with external redundancy (SAN) and 500G size.
My question: If the diskgroup has lower then 500G free an EM Metric will alert us that no disk can safely removed from that diskgroup. Ok, this reproducable for me regarding diskgroups with normal redundancy (failure groups) but not for DG with external reduncay disks.

I've not checked this yet: But hopefully an defined error occurs if I try to remove a disk from a diskgroup, if the other disk in DG won't take over the blocks from that disk during rebalancing because the space is to low.
