Daily Security Run Output / READ_DMA / Command Timeout

[PaddyNo]

Hi Community

I'm getting the following security output all the days, but honestly, I couldn't find any reference if this could be an issue or not. The latest stable updates of v9.3 are installed.

my_freenas.local kernel log messages:
> (ada4:ata0:0:1:0): READ_DMA. ACB: c8 00 a6 e0 b0 40 00 00 00 00 01 00

Very appreciated if anyone could give me a hint how to interpret these messages.

Post the output of:

sas2flash -listall
smartctl -a /dev/ada4

Hint: If you've searched the forums for "command timeout" you'd probably have found 20+ threads that would tell you how to identify the problem for yourself... ;)
