1.23 SMART Error Log Reporting

IDE type disk drives, whether they use serial ATA (SATA) or parallel ATA (PATA or just ATA) interfaces, offer an

abundance of diagnostic and reporting capability. They are part of the SMART command set which is supported in all

but the earliest generation of ATA disk drives. The error logging contains volatile and non-volatile information and you

can somewhat equate that to the log page reporting found in SCSI family disk drives.

This feature was released in version 1.23.

Usage:

smartmon-ux -O [options] [device_list]

Sample Output:

[root@morph smartmon]# ./smartmon-ux -O

Discovered Maxtor 6Y080M0 S/N "Y3JRAGXE" on /dev/hda (SMART Enabled)

Cumulative errors recorded by disk: 0

Discovered SEAGATE ST39102LC S/N "LJT22233" on /dev/sda (SMART enabled)(8683 MB)

Discovered SEAGATE ST39102LC S/N "ZJ904241" on /dev/sdb (SMART enabled)(8683 MB)

Program Ended.

Analysis: Note that this command was issued on a system that had two SCSI disks and an ATA disk. The

ATA disk at /dev/hda reported no errors, and the two SCSI Seagate disks ignored the command entirely since

the SMART Error Log Reporting is a feature that is unique to SATA and PATA disks.
