What Do I Do If I Get an Alert 223

2 What Do I Do If I Get an Alert

2.1 What Does an Alert Look Like?

Disk-Related Messages

In the event a S.M.A.R.T. alert is generated by your disk drive, it will be detected by SMARTMon-UX the next time the

program polls the disk. If you have the email option (-M) invoked, your system will send out an email similar to: "

Device on /dev/hd1 SMART Status:FAILED - Failure imminent".

The message header will be "SMARTMon Alert from computer.domain." (i.e., SMARTMon Alert from

system.mydomain.com).

You should take some immediate actions to minimize possibility of data loss.

In addition, this information will be recorded in the Windows Event log or smartmon-ux.log if running Windows family

operating systems or the standard UNIX/LINUX syslog file. See use of the -L and -LRemote command to

control the names of the log files for your particular operating system. The example below shows what the software

reports on a failing SAS disk

# tail /var/log/smartmon-ux

Enclosure-Related Messages (SES)

If you have a component fail in your SES enclosure, the message text might contain something like:

PSU #0 Critical DC failure [LED ON] XYRATEX SS-1202-FCAL 50-05-0C-C0-00-00-3D-DD

The SES code within SMARTMon-UX returns status text messages for all SES pages defined within the specification.

Note that not all SES enclosures monitor all components defined in the spec. You should contact your storage vendor

to learn which SES Components monitor their hardware. Below is a list of components that SMARTMon-UX

monitors and reports

· SES Device Status Element (i.e., disk drive status)

· SES Array Element (i.e., is the device a hot spare, part of a critical array, rebuilding, etc...)

· SES Cooling Element (fans, and fan speed)

· SES Temperature Element (returns temperature and thermal overtemp/undertemp warnings)

· SES Power Element (includes over/under voltage and AC/DC power loss)

· SES Door Lock Element (for each device bay)

· SES Audible Alarm Status Element (muted, enabled, sounding, etc...)

· SES Electronics Status Element

· SCC Electronics Status Element

· SES Volatile Cache Status Element

· SES UPS Status Element (includes battery status, and AC/DC power status)

· SES SCSI Port Status Element

· SES Language Element Status Element

· SES Communication Port Status Element

· SES Voltage Sensor Status Element (displays input voltage)

· SES Current Sensor Status Element (displays current drawn)

· SES SCSI Initiator Port Status Element
