Cache Module Satus failed, at second controller P420

[MiguelC]

Hello all! 
I´ve one DL 380 G8 with two cages with 8 disks, first one connected directly to P420i original controller, and second cage connected to a P420 controller connected at riser Slot 3 PCIe. O.S. is Vmware ESXi 6.0.0, a few days ago all virtual machines using Datastore of cage two, was without contact, after one reboot with error reporting cache module, and other second boot hardware starts disks at cage two. They have enought time to migrate VM´s.
Now at ILO views System Information->Storage Information, as picture shows the controller at slot 3 P420 is ok at Status, but it is red at Cache Module Status as "Failed", my first action was change the battery capacitator, they change it at yesterday afternoon but status is the same at report !

Obs.- Raid is also degraded for this cage, for sure because cache error!

Can anybody help me to solve this error? I also noticed something about PSU´s generating this situation, this DL380 G8 have P420i dor first cage and P420 for second cage and works fine near one yar and half without any error, PSU´s are reporting normal condiction.
Thank you for the help

Hi there, 

I know that will sound very obvious but did you try to re-seat cache module?

I came across few times that sometimes simple re-seat cache can solve error or selt-test error on RAID controller.

Thanks
