Abstract
A method and apparatus to dynamically order features and manage features, especially aggregators, during creation of a logical volume is provided. The method and apparatus make use of a partition/aggregate list to identify partitions and/or aggregates that make up a logical volume that is to be created. In addition, the partition/aggregate list identifies features to be applied to the partitions and/or aggregates as well as the order in which these features are to be applied. The order in which these features are to be applied is designated by a current feature indicator (CFI). Based on a current CFI count of an entry in the partition/aggregate list, application of a feature corresponding to the current CFI count is attempted. If successful, the current CFI count is incremented and the process returns to a first entry in the partition/aggregate list. If unsuccessful, the current CFI count is not incremented and the process continues on to the next entry in the partition/aggregate list.
