SMART
Self-Monitoring, Analysis and Reporting Technology (SMART) is a technology built into modern hard drives to monitor the health of the drive and anticipate failures. The two classes of failures are: predictable and unpredictable. Examples of predicable failures are increased number of bad sectors and increased temperature from wear; they typically occur from slow processes. Unpredictable failures occur without warning and suddenly; for example, a hard drive dropped may report more than a normalized number of read errors.
The hard drives within Luna Network HSM 7 appliances implements SMART. A background process called the SMART control daemon (smartd) starts automatically at power up and is responsible for monitoring the hard drive via the SMART technology in it. The daemon records its findings via syslog.

SMART Attributes
From LunaSH, you can query the SMART attributes. The example below shows the SMART attributes reported from the shell command lunash:>status disk:
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 0 3 Spin_Up_Time 0x0027 154 152 021 Pre-fail Always - 1300 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 601 5 Reallocated_Sector_Ct 0x0033 200 200 140 Pre-fail Always - 0 7 Seek_Error_Rate 0x002e 200 200 000 Old_age Always - 0 9 Power_On_Hours 0x0032 099 099 000 Old_age Always - 1383 10 Spin_Retry_Count 0x0032 100 100 000 Old_age Always - 0 11 Calibration_Retry_Count 0x0032 100 100 000 Old_age Always - 0 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 601 192 Power-Off_Retract_Count 0x0032 200 200 000 Old_age Always - 138 193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 462 194 Temperature_Celsius 0x0022 115 092 000 Old_age Always - 28 196 Reallocated_Event_Count 0x0032 200 200 000 Old_age Always - 0 197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0030 200 200 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 1 200 Multi_Zone_Error_Rate 0x0008 200 200 000 Old_age Offline - 0
The ID# and ATTRIBUTE NAME columns are the SMART attribute defined by the drive vendor. Note that vendors have generally standardized on the attributes and their meaning. The FLAG column indicates the main purpose of each attribute; correlating to the text in the TYPE and UPDATED columns. Only the last two bits are of any significance. Bit 0 identifies whether the attribute is an advisory (0) or a pre-fail notification (1). An advisory means that the disk has exceeded its intended design life while a pre-fail notification means that the disk is predicated to fail within 24 hours. Bit 1 indicates whether attribute monitoring occurs strictly offline (0) or during offline and normal operations (1).
The RAW_VALUE, VALUE, WORST and THRESH columns report on the specific attribute. The drive controller reports the RAW_VALUE. VALUE is normalized where a higher value is better. As VALUE drops (i.e., becomes worse), it approaches a threshold. THRESH is the value at which SMART reports a ‘threshold exceeded’ event. WORST is the most extreme reading recorded for the attribute. A VALUE of 100 is an initial default value. Consider attribute #174 (Temperature) as an example to put these four values in context. The example shows the current temperature reading of the drive as 28 degrees Celsius. Normalized, this reading is 115. A value of 100 therefore is 43 degrees Celsius. The worst reading recorded is a normalized value of 092 which translates to 51 degrees Celsius. This attribute has no threshold as it represents an advisory.
Assume that the SMART control daemon generated the following log message:
2012 Feb 29 12:05:01 myLuna daemon info smartd[1234]: Device: /dev/sda, SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 200 to 92
The next query of the SMART attributes might report the following information for attribute #1:
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 092 092 051 Pre-fail Always - 37767785
If the drive controller reads a value that, once normalized, is less than or equal to the THRESH value, the daemon generates a critical log message and a query of the SMART attributes reports a VALUE less than or equal to THRESH as the following example shows.
2012 Feb 29 12:05:01 myLuna daemon crit smartd[1234]: Device: /dev/sda, SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 92 to 51 ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 051 051 051 Pre-fail Always FAILING_NOW 4528445
The WHEN_FAILED column indicates that the attribute has reached the THRESH value.

Adding to "monitor" list. 2012 Feb 29 12:05:01 myLuna daemon info smartd[1234]: Monitoring 0 ATA and 1 SCSI devices
These messages indicate that the SMART control daemon was successful in starting up and identifies the type and number of each device the daemon is monitoring. For Luna Network HSM 7 appliances, only one serial ATA device applies. The daemon opens the device to query its capabilities [the first message in the examples above]. The daemon uses SCSI/ATA Translation (SAT) to enable communication with the drive [the second message]. In SAT mode, the daemon reopens the device [third message] and looks for it in an internal database [fourth message] but does not find an entry for the device. The smart.conf file sets the directives for the daemon and these directives include attribute autosave (-S on) and automatic offline testing (-o on) [fifth and sixth messages]. Turning on attribute autosave instructs the disk drive to use non-volatile storage for attributes such as error counters, power-up hours and other useful data so that these values do not get reset to zero the next time the device is power-cycled. Turning on automatic offline testing instructs the drive to update certain SMART attributes every four hours. The disk used in the Luna Network HSM 7 appliance is SMART-capable [seventh message] so the daemon monitors it [eighth message].
In preparing this document, Thales reviewed the source code of a newer version of the smart control daemon. Thales plans to update the daemon at some future date. The next set of messages show the messages this new daemon outputs at start up.
