Hi all and first and for most thank you for all the good work you all do. 

We have 2 VNX5400 and an EMC UNITY that we retired back in 2018 and now trying to get it back in life for learning and practicing purposes. Warranty and service contracts are expired so trying to get this done on our own and help of our service provider. We powered the VNX up and one of the SP A was not getting power so we took the power supply from the other DR VNX and got the SP A to power up. We are able to get in to CLI and Unisphere and get a bunch of 0x126083021b Critical Errors Enclosure 0 CPU module B DIMM 0 - 5 Faults and also 0x1260830218 Enclosure 0 Fault occurred errors. also Data Mover B is offline and PS for that has a blinking triangle. We are looking to clear all the errors using spare parts from our DR VNX and also default everything to scratch as we are not using our ESXi environment any more we most likely will use this as a NVR storage for our corporate cameras or as a storage for our inhouse IT cloud or smth more as a leraning curve. Any suggestions, ideas or pointers on where to start and so would be appreciated. 

Thank You
