Assigning or Unassigning Dedicated Hot Spares

A dedicated hot spare is an unused backup disk that is assigned to a virtual disk. When a physical disk in the virtual disk fails, the hot spare is activated to replace the failed physical disk without interrupting the system or requiring your intervention.

You must have Login and Server Control privilege to run this operation.

Only T10 PI (DIF) capable physical disks can be assigned as a hot spare to T10 PI (DIF) enabled virtual disks. Any non T10 PI (DIF) drives that are assigned as dedicated hot spare will not be a hot spare if T10 PI (DIF) is enabled on a virtual disk later on.

You can assign only 4K drives as hot spare to 4K virtual disks.

If you have assigned a virtual disk as a dedicated hot spare in Add to Pending Operation mode, the pending operation is created but a job is not created. Then, if you try to unassign the dedicated hot spare, the assign dedicated hot spare pending operation is cleared.

If you have unassigned a virtual disk as a dedicated hot spare in Add to Pending Operation mode, the pending operation is created but a job is not created. Then, if you try to assign the dedicated hot spare, the unassign dedicated hot spare pending operation is cleared.
