Stork-scheduler pods don't come up because of ImagePullBackoff error

Portworx Install

Hello.
I’ve just installed Portworx 2.9.1.3 (for CP4D) on our internal Baremetal OCP4.10 cluster with the file “CP4D_ENT_ED_Portworx_2.9.1.3.tgz”. “pxctl status” command says that it’s operational,but all of stork scheduler pods fail to start up due to “ImagePullBackoff” error as below:

The result of “oc describe pod” command shows that it’s requesting the image “kube-scheduler-amd64:v1.21.4”, but the zip file doesn’t contain the image (instead kube-scheduler-amd64:v1.21.1 is included in it).
How can I get v1.21.4 image?

Hello. I succeeded downloading “stork-scheduler v1.21.4” image and pushed it to our private registry.
However it doesn’t seem to work with the other images and all the new pods failed due to “CreatingContainerError”.
So I editted “stork-scheduler” deployment definition and replaced the image tag with “v1.21.1” that is included in the installation zip file.
One of the three pods started running, but since it is controlled by its operator pod, the definition was updated just after that and the other pods failed to start up.
How can we change the image tag used by portworx?
