D.11 sdxroot - Root file system mirroring definition and
cancellation [PRIMEQUEST]
SYNOPSIS
sdxroot -M -c class -d disk[,disk,...]
sdxroot -R -c class -d disk[,disk,...]
DESCRIPTION
Use sdxroot to complete or cancel mirroring definition of system disks including root file systems. The "sdxroot" command can be executed
with superuser access privileges only.
System disk means the physical disk on which the running Linux operating system is installed. Specifically, it means the entire disk that
includes a slice currently running as any one of the following file systems (or a swap area).
/, /usr, /var, /boot, /boot/efi, or swap
PRIMARY OPTIONS
You can use one of the following options.
-M
Make
Checks that one or more system disks specified by disk are ready for mirroring (registered with a class and connected to a group) and
creates remaining mirroring definitions*. After returning from this command, reboot the system immediately. After the system is
rebooted, system disk mirroring will commence.
*) Update the following system files and so on.
For RHEL4 and RHEL5: fstab and elilo.conf
For RHEL6
: fstab, grub.conf, and dracut.conf
Specify a disk that includes a slice currently running as / (root), /usr, /var, /boot, /boot/efi, or a swap area for disk. Among / (root), /
usr, /var, /boot, /boot/efi, and swap areas, although it is not required to specify disks with swap areas only, be sure to specify disks
with / (root), /usr, /var, /boot, and /boot/efi. Additionally, the disk specified by disk must be ready for mirroring (registered with a class
and connected to a group).
When synchronization copying is being performed in groups to which the system disks are connected, the sdxroot command results
in an error. In this situation, cancel the synchronization copying using the sdxcopy -C command, or execute this command after the
synchronization copying is completed.
