ABSTRACT:
A technique forecasts the behavior of a RAID subsystem when processing a proposed configuration management request that modifies a topology or attribute configuration, e.g., RAID groups and volume layout, of a storage array managed by the subsystem. In response to the proposed request, the RAID subsystem returns a set of projected result data instead of committing the request to the storage array configuration. An operator issues the proposed request in accordance with a novel view-only mode of a configuration management command. The view-only mode is manifested as an “-n” option that instructs a configuration thread of the RAID subsystem to return pre-committed results without actually committing the modification.
