QuestionQ10

Storage management tools

A drive in a VSP One B24 system is configured in a Dynamic Drive Protection (DDP) group.

If this drive becomes blocked because of a failure, which process automatically begins to keep the DDP redundant?

  • A Correction Copy with spare drive
  • B Correction Copy with spare areas on drives
  • C Dynamic Sparing with spare areas on drives
  • D Dynamic Sparing with spare drive
Explanation

Dynamic Drive Protection reserves spare areas on the drives in the group, so no dedicated spare drive is required. When a drive fails and is blocked, Correction Copy reconstructs the protected data into the distributed spare areas, restoring DDP redundancy. Hitachi’s VSP One Block documentation distinguishes drive-failure-triggered Correction Copy from Dynamic Sparing and identifies spare-area use within DDP configurations.
