     282==== Configure coercion (limit disk size to maximize compatibility with different vendors) ====
     283
     284All 4 Tb drives do not have the exact same size so it's recommend to use coercion feature to floor the actual size a bit to maximize compatibiliy.
     285
     286Get current value:
     287{{{
     288server:~# megacli -AdpGetProp CoercionMode -a0
     289
     290Adapter 0: Coercion Mode : Disabled
     291}}}
     292
     293Available values are 0 for disabled, 1 to floor at 128Mb, 2 to floor at 1Gb, I personnally recommend going for 1G:
     294{{{
     295server:~# megacli -AdpSetProp CoercionMode 2 -a0
     296
     297Adapter 0: Set Coercion Mode to 2 success.
     298
     299server:~# megacli -AdpGetProp CoercionMode -a0
     300
     301Adapter 0: Coercion Mode : 1GB
     302}}}
