As the result of running exachk tool, one of WARNING messages I got is " Cache is disabled on Local SSD".
details of this message:
DATA FROM EL01CN01 - ENABLED CACHE ON LOCAL SSD
Adapter 0-VD 0(target id: 0): Cache Policy:WriteThrough, ReadAheadNone, Direct, No Write Cache if bad BBU
Exit Code: 0x00
What this message is all about, and how to clear it up?
To fix this issue, turn the cache on by running the following commands:
/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp Cached -L0 -a0/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp WB L0 -a0
Hope this helps.
