The start storageArray controllerHealthImage controller command produces a storage array controller health image on storage arrays that support the controller health image feature.
This command applies to an individual DE2000H, DE4000H, DE4000F, DE6000H, or DE6000F storage array.
To execute this command on an storage array, you must have the Storage Admin role.
If the storage array does not support the controller health image feature, the command returns an error.
