Turning off S.M.A.R.T.
The easiest way to disable S.M.A.R.T. is to use the command-line option, -p. This command option searches for all SCSI / FC / SAS disks, and disables S.M.A.R.T. on those disks that currently have it enabled. The change will affect only the current setting, and a power cycle will revert the disk to the default setting where S.M.A.R.T. is disabled.
Examples
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)
If you wish to enable S.M.A.R.T. so that the change is non-volatile, then substitute -pp for -p in the examples above. This function has not currently been translated to a widget.
Notes:
| • | Enabling S.M.A.R.T. for SCSI, FC, and SAS 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 currentmode 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. |
| • | S.M.A.R.T. has several configurable parameters beyond just turning it on and off. These parameters may make a difference to your host operating system (or a RAID controller), so you should contact your hardware vendor before modifying the settings. |
| • | You can use several methods to modify these other settings, like using command-line options, -mpimport, -B, or the Mode Page Editor. |
As always, never make changes to mode pages unless you know what you are doing. We suggest that if you want to disable S.M.A.R.T., use the new -p command described in this section. If you want to disable S.M.A.R.T., so it stays disabled, even after power cycles, then use the -pp command.
You should also look at the Mode Page 1C settings which provide more information on these and related topics.
