The NetApp Flash Pool Design and Implementation Guide (TR-4070, attached) states on page 9. Flash Pool(s) can be configured on a volume-by-volume basis.
Ok, so with that being said I disabled read and write cache using the commands straight out of the doc. I am performing these steps on SnapMirror destinations.
priority hybrid-cache set sm_vol_pcinscl1_data_dest read-cache=none
priority hybrid-cache set sm_vol_pcinscl1_data_dest write-cache=none
So then I wanted to check and see if the commands had in fact taken. But I wasn't exactly sure how and so I was poking around a little bit. I ran the command below and received the following results.
ppnrdnetapp1*> priority show
Priority scheduler is stopped.
Priority scheduler system settings:
My question is this. In order for my cache policies to apply, does the Priority scheduler need to be running? Or are they enabled simply by running the first command I mentioned? I couldn't really find anything in the TR which states otherwise.
I noticed that if I ran the command below I can see that a policy has been applied to a volume.
priority hybrid-cache show sm_vol_pcinscl1_data_dest
Read Cache Policy: none
Write Cache Policy: none
So I just want to make sure I'm good here. Any assistance is greatly appreciated.

Just to close the loop on this. I did some digging and the answer to my question is no.

No, you don't need priority scheduler to be running inorder for your policies to take effect.
