Start storage array controller health image

09/10/2024 Contributors

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 E4000, E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.

Roles

To execute this command on an E4000, E2800, E5700, EF600, or EF300 storage array, you must have the Storage Admin role.

Context

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.

Syntax
