Information in this document applies to any platform.
This procedure describes how to resize ASM disk groups to shrink one with excess free space and grow another that is near capacity. Typically, the RECO disk group will be shrunk down and the DATA disk group will grow. This procedure works particularly well in cases where the DATA disk group is almost full and the RECO disk group has enough free space to permit rebalancing at least a single cell’s worth of data.
If your grid disks have sufficient free space to expand your disk group, then you may be able to use the simpler procedure in note 1684112.1.
