The sdxsystem command is used to forcibly cancel the settings for system disk mirroring in a UFS boot environment.
You can use this command when a system error occurs and you cannot cancel the system disk mirroring by the usual method.
The sdxsystem command deletes the configuration information of system disk mirroring from the files below and deletes the private slice from the system disk:
/etc/system file
/etc/vfstab file
/kernel/drv/sfdsk.conf file
You must be superuser to use this command.
Note
Usually, the mirroring cancellation of the system disk is performed according to "5.1.9 Unmirroring the System Disk" or "Chapter 7 How to Set and Cancel System Disk Mirroring Using Commands." If you can cancel the system disk mirroring by the usual method, do not use the sdxsystem command.
When one of the following conditions is met, the sdxsystem Remove command cannot be used:
When the environment is a ZFS boot environment.
When the physical disk name (cXtYdZ) is different from the one when the system is started from the system disk
Example: When the system was started from a CD-ROM device in SPARC M12/M10.
For use of sdxsystem, see the following:
"(4) System cannot be booted (Failure in all boot disk devices)." in "F.1.5 System Disk Abnormality"
