We have created a ASM diskgroup with normal redudancy, (MAINGP) with two
failure groups (DATA1,DATA2).

We are bit confused with two different answers from two different people
about writing behavior.

Our question was, "when DBWR wants to write the data to the disk, does it
waits until it complete the writing process on the both groups? OR DBWR
completes one write and return, then, ASM replicates the to the failure
