Description edit

This command is used to see DMD options and status

Run “disk walk 10” to display side by side: ManagementDiscipline, DesiredManagementDiscipline, OperStatus, OperMode

When to Use edit

Raid – Desired Management Discipline This attribute, available on disk objects, was put in to eliminate the need for temporary disk folders and to try and automate the tasks that involved them. There are four valid values that you can set for a DesiredManagementDiscipline:

  1. Unassigned a. Used to migrate off a managed disk b. Disk set <index> DesiredManagementDiscipline Unassigned
  2. ManagedSpare a. Used to reclaim a spare. b. Disk set <index> DesiredManagementDiscipline ManagedSpare
  3. Failed:
    • Used to restripe off a disk that you want brought down for replacement
    • This is actually the safest way to fail a disk that isn’t causing loop or performance problems, because hidden medium errors on disks in the same stripe shouldn’t cause problems
    • Disk set <index> DesiredManagementDiscipline Failed
  4. Managed:
    • Used to undo one of the previous values
    • Disk set <index> DesiredManagementDiscipline Managed
