Smart Attributes

Process Overview

Introduction

SMART attributes is a monitoring system for hard disk drives to detect and report on various reliability indicators. LabTech scans for SMART information, if enabled on the computer, when hard drive information is gathered on the agents. This information is displayed on the Drives tab within the Computer Management screen.

NOTE: SMART must be enabled on the motherboard, hard drive and in the operating system.

To access the SMART attributes in LabTech:

From the Control Center, select Dashboard > Config > Configurations > Smart Attributes.
Figure 1: Smart Attributes

Adding Smart Attributes

If there are attributes that are not in the current list of attributes, you can add additional attributes. To add attributes, follow the instructions below:

From the Smart Attributes tab, select Clear to clear the fields and enable the Add button.
Enter the Name of the attribute.
Enter the AttributeID.
Enter a Description for the attribute.
Click Add. The new attribute will be immediately added to the list.

Deleting Smart Attributes

If an attribute is not valid, you can delete it from the list. To delete a smart attribute, follow the instructions listed below:

From the Smart Attributes tab, right-click on the attribute to delete and select Delete. You will be prompted to confirm.

TIP: You can select multiple attributes by holding down the [Shift] key or using the [Ctrl] key.
Select Yes to delete or No to cancel. The attribute will be immediately deleted from the list.

Editing Smart Attributes

From the Smart Attributes tab, highlight the attribute to edit. The Add button will change to a Save button.
Make the desired changes. Click Save.

Exporting Selected Attributes

These attributes can be imported into other systems. To export as a .SQL file or LabTech expansion, follow the steps listed below:

From the Smart Attributes tab, highlight the attribute(s) to export. You can select multiple attributes by holding down the [Shift] key or using the [Ctrl] key.
Click the Export Selected button. You will be prompted to select the location to export the file to.
Navigate to the location you want to save the file.
Enter the File name.
Select 'SQL File' or 'LabTech Expansion' from the Save as type: drop-down.

170	Reserved Block Count	Indicates the number of reserved bad block handling.
171	Program Fail Count	Indicates a number of flash program failures.
172	Erase Fail Count	Four bytes used to show the number of block erase failures since the drive was deployed.
173	Wear Leveling Count	Indicates the worst case erase count.
174	Unexpected Power Loss	Indicates a number of unexpected power loss events.

182	Erase Fail Count	Four bytes used to show the number of block erase failures since the drive was deployed.
183	SATA Downshift Error Count	Western Digital and Samsung attribute.
184	End-to-End Error	This attribute is a part of HP's SMART IV technology and it means that after transferring through the cache RAM data buffer the parity data between the host and the hard drive did not match.
185	Head Stability	Western Digital attribute.
186	Induced Op-Vibration Detection	Western Digital attribute.
187	Reported Uncorrectable Errors
188	Command Timeout	The count of aborted operations due to HDD timeout. Normally this attribute value should be equal to zero and if the value is far above zero, then most likely there will be some serious problems with power supply or an oxidized data cable.
189	High Fly Writes	HDD producers implement a Fly Height Monitor that attempts to provide additional protections for write operations by detecting when a recording head is flying outside its normal operating range. If an unsafe fly height condition is encountered, the write process is stopped, and the information is rewritten or reallocated to a safe region of the hard drive. This attribute indicates the count of these errors detected over the lifetime of the drive.
