how to use the readzila ssd on partner controller with cluster (vdi) after takeover occurred ?

Hi, All;

We have configured the VDI environment with ZS3-2 Cluster.
There are two READZILA SSD. and one pool (mirrored profile).
Each controller has one READZILA.

I create the pool-0 with one cache (readzila ssd) on controller #1.
there is installed on slot3 of controller #1.

I would like to use the readzila on controller#2, when takeover was occurred for cache.

  I would like to set as following description. Is it possible ?

       1. controller #1 has pool-0 (active/standby cluster). cache ssd is installed on slot3 of controller#1.
       2. If takeover be occurred. cache (reazila is unavailable status).
          So I would like to use the readzila of controller#2, to keep the performance during takeover status.
