Thank you for sharing the log file. I see you had issue with drive at location Enc 1 Slot 4 with Serial number: 6SL0XMBK0000N141GHSE and drive model: ST3600057SS. This drive was failed on 24th Feb 2018 and later replaced by another drive with Serial number: J9VB0XZL and drive model: EF0600FATFF
As Shawn mentioned I have same opinion that drive model EF0600FATFF not part of MSA drive matrix so shouldn't be used. I see in this system you are using same drive at location Enc 1 slot 4 as well as Enc 1 Slot 6
From the logs I see the moment new drive used as Global spare and vdisk reconstruction started. New drive started logging medium errors and other errors. So 1st impression this drive itself looks bad to me. 2nd thing this drive not supported with P2000 box. Attached is the screenshot of drive error counter for your reference
Now coming to major portion, this system running with expired or unsupported version of Controller firmware TS201R015 whereas latest available firmware TS252P005. So any abnormal behavior expected. Please follow the customer advisory which was released sometime back which covers this. This is not latest document but contains useful information about firmware,
My suggestion would be to use HUS156060VLS600 or ST3600057SS or EH0600JDYTL like you are already using in other slots. These are supported models for MSA. Then consider upgrading Controller firmware and drive firmware by planning downtime as you are running with expired version now.
