Start storage array controller health image

Contributors netapp-driley

The start storageArray controllerHealthImage controller command produces a storage array controller health image on storage arrays that support the controller health image feature.

Supported Arrays

This command applies to any individual storage array, including the E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.


To execute this command on an E2800, E5700, EF600, or EF300 storage array, you must have the Storage Admin role.



With firmware version 8.20 the coreDump parameter is replaced with the controllerHealthImage parameter.


Use this command only under the direction of technical support.

If the storage array does not support the controller health image feature, the command returns an error.


start storageArray controllerHealthImage controller [(a|b)]


Parameter Description


This parameter specifies the controller from which to produce the controller health image. Valid controller identifiers are a or b, where a is the controller in slot A, and b is the controller in slot B. Enclose the controller identifier in square brackets ([ ]). If you do not specify a controller, the storage management software returns a syntax error.


This command forces the selected controller to dump its core data to cache. Use the save storageArray controllerHealthImage command to save a copy of the cache data to a host file.

Minimum firmware level


8.20 replaces the coreDump parameter with the controllerHealthImage parameter.
