The S.M.A.R.T monitoring feature supports SATA hard drives enabled with SATA in AHCI mode and RAID mode. It has integrated capability to monitor S.M.A.R.T alerts through iDRAC supported auditing methods for hard drives under SATA chipset controller. Previously alerts were monitored by any open-source utility to monitor the hard drives set in RAID mode.
Table 1. Attribute values and descriptionThis feature is controlled by an attribute registry
iDRAC.Embedded.1#ServiceModule.1#ChipsetSATA with the following values:
Attribute Values
Description
Enabled
The chipset SATA controllers are monitored for S.M.A.R.T events in real time.
Disabled
S.M.A.R.T monitoring is disabled.
NA
Chipset SATA controller is not available.
NOTE By default, the S.M.A.R.T attribute is set to
Enabled or
NA when the configuration does not support chipset SATA.
S.M.A.R.T monitoring is a feature that is installed through the iSM installer. You can install or modify the iSM installer package to disable the S.M.A.R.T monitoring feature. This feature is available on a Dell EMC on supported SATA disk with S.M.A.R.T capabilities.
If the disk is S.M.A.R.T capable and the feature is enabled, iSM monitors the disks and generates events accordingly. The default monitoring period is 24 hrs and cannot be manually configured. Only PDR16 (predictive failure) and PDR22 (temperature threshold exceeded) events are monitored.
If there is an operating system error due to a S.M.A.R.T error of the drive, then the event is not detected by the operating system. If hard drives are part of a storage pool, then iSM does not monitor the drives for S.M.A.R.T failures.
On PowerEdge yx3x servers, S.M.A.R.T monitoring using software RAID is applicable only for the PDR22 event.
NOTE S.M.A.R.T also requires iDRAC9 firmware 4.00.00.00 or later to be installed.
