but when I try to create ldcache I get the following error:

=> ctrl slot=0 create type=ldcache drives=5C:2:5 datald=2

Error: This operation is not supported with the current configuration. Use the
       "show" command on devices to show additional details about the
       configuration.
Reason: Not supported

What am I doing wrong?

Are there any other restrictions besides the ldcaсhe array?

Hi Montana,

The smart cache using SSD is not available with P410i controller. 

This feature is introduced from Gen8 series servers and supported controllers.
