SmartCTL, Hardware Raid, Errors in Syslog?

[Nefariousparity]

Hello, we have two Dell R720XD (12Bay) servers 2x Drives for 10x drives for datastore. This is hardware raid 1 and hardware raid 10. In syslog on both servers I see this. These numbers seem pretty static like they don't change often, however I do have replacement drives for both of these servers. I just don't know how potentially critical this is and if I should start replacing drives immediately. Thank you for looking!

Hey

smartctl error are never good x'D

But, maybe check HW raid doc for better enderstanding ?

there is nothing to worry about
it is the temperature on the Fahrenheit scale
for example:
75F = 24C
85F = 30C
115F = 46C
Worry about the SSD when the temperature reaches:
149F - 65C = attention - check cooling
158F - 70C = critical - replace the drive
