Analysis: Both of these drives have been used in a system for a significantly longer time, and you see they
have all recorded errors. In the case of the Maxtor disk, you will see that there are also extended error bytes
which are vendor-unique.
Notes:
· The -O option may be added to the command-line with other options. If the -O option is used, however, the
program will automatically terminate after reporting all relevant information. The program will not launch and run in
the background after discovering the devices.
· The -O option will only report information if the selected device is capable of reporting such information. Disks that
do not support the SMART Report Error Log will ignore the command.
· The -O option reports really advanced stuff. Many of the "errors" it reports may be perfectly normal. SANtools does
not interpret this information for you, but your hardware and/or disk drive vendor or supplier should be able to
analyze the information for you, provided you are having some sort of problem. If you are a storage engineer,
however, you will find this feature invaluable.
· The -O option can be combined with other reporting options such as -I or -S .
· This function works with SPARC Solaris, Windows family operating system, LINUX, and OS X.
1.24 Enabling, Disabling, Controlling S.M.A.R.T
Enabling S.M.A.R.T. Polling
SMARTMon-UX enables S.M.A.R.T. polling by default. If you invoke the program with no options at all, the program
will scan for all disk drives, enable S.M.A.R.T. as each disk is discovered, and relaunch into the background after
information has been reported. Details for each operating system is described with additional details in the Principles
of Operation section.
If you are running a Windows-family O/S, the MS-DOS box will stay open and the program will continue to run in that
window. That is because the O/S does not provide a convenient method to run a command-line program as a
background job.
Turning off S.M.A.R.T.
With version 1.23, we added a new command option, -p. This command option searches for all SCSI & fibre channel
disks, checks to see if S.M.A.R.T. is turned on, and disables it. When all of the devices have been scanned, it exists
the program. The -p option also reports what state that S.M.A.R.T. was in for the selected disks as they are
discovered.
Example: ./smartmon-ux -p /dev/sga /dev/sgb (Disables S.M.A.R.T. for these two disks)
./smartmon-ux -p (Disables S.M.A.R.T. for all disks)
(Substitute -pp for -p in commands above to make the change non-volatile, so S.M.A.R.T. stays off
even after recycling power).
Notes:
Enabling S.M.A.R.T. for SCSI and Fibre Channel disks requires making a change to mode page 1C. Per the
S.M.A.R.T. specification, we do not make the change permanent by programming the device using the saved
mode page. We only modify the current mode page . That means once you recycle power on your disk drives,
the disk will revert to whatever state it was in before invoking SMARTMon-UX.
If you wish to permanently configure your disk so that S.M.A.R.T. is always enabled (or disabled) at power-on, you will
need to make appropriate changes to the disk's mode page using the mode page editor function. This can be done by
