Security Run Output Email

[Clinderw]

I got this email this morning but upon searching for SCSI i didnt get much back...

freenas.local kernel log messages:
> (da1:mps0:0:1:0): WRITE(16). CDB: 8a 00 00 00 00 01 50 45 62 f8 00 00 00 08 00 00

-- End of security output --

Any thoughts what it means?

Thanks,
