S.M.A.R.T. data on RAID configurations.

Hardware RAID

Most RAID controllers today do not support accessing the S.M.A.R.T. data of the various hard disk drives attached to them. This includes separate RAID controller PCI or PCIExpress cards as well as integrated RAID controller chips on the mainboard. Examples for these are Promise, Adaptec, Intel, JMicron and Silicon Image RAID controllers.

These controllers or the drivers required to use them are blocking any software from reading the values of the SMART attributes. Unfortunately, there is no way for Argus Monitor to access S.M.A.R.T. data on these RAID configurations.

There are however exceptions to this. Some RAID controller families from 3ware / AMCC and Areca can provide the S.M.A.R.T. data with proprietary pass-through commands. Currently Argus Monitor does not support these commands either. In case there is a growing number of users using these controllers, support for these controllers could be added in the future.

 

Software RAID

If you are running a RAID array using the software RAID functionality of your Microsoft Windows operating system, S.M.A.R.T. data can be accessed as with any other hard disk drive running in standard AHCI oder IDE mode.
