parity group
selection rule
This is the rule specified when you want to select a migration target after
considering the usage status of parity groups. This rule has the following three
options:
- BalanceCapacity: Selects migration target volumes so that the parity groups
that are selected as the migration destination have the same amount of remaining
capacity.
- MaximumCoverage: Selects migration target volumes from as many parity
groups as possible.
- MinimumCoverage: Selects migration target volumes from as few parity groups
as possible.
