It is allowed for the storage cluster to be at an earlier version than IBM Storage Scale container native client cluster. CSI functions are highly dependent upon the release, file system level, and version of IBM Storage Scale installed on the storage cluster. If the storage cluster is at an earlier version, some functions may not be available. For more information about the minimum levels required for specific CSI functions, see Hardware and Software Requirements in the IBM Storage Scale CSI documentation. For more information about compatibility and software matrix, see Section 17.3 in the IBM Storage Scale FAQ documentation.

IBM Storage Scale container native doesn't support secure boot, the secure boot feature needs to be disabled for Red Hat OpenShift Container Platform nodes

IBM Storage Scale Container Storage Interface (CSI)

IBM Storage Scale Container Storage Interface (CSI) will be installed along with IBM Storage Scale container native.
