metaroot - setup system files for root (/) metadevice SYNOPSIS
/usr/sbin/metaroot -h /usr/sbin/metaroot [-n] [-k system-name] [-v vfstab-name] [-c] [-m md.conf-name] [-R root-path] device DESCRIPTION
The metaroot command edits the /etc/vfstab and /etc/system files so that the system may be booted with the root file system (/) on an appropriate metadevice. The only metadevices that support the root file system are a stripe with only a single slice or a mirror on a sin- gle-slice stripe. If necessary, the metaroot command can reset a system that has been configured to boot the root file system (/) on a metadevice so that it uses a physical slice. OPTIONS
Root privileges are required for all of the following options except -h. The following options are supported: -c Use instead of the default /etc/lvm/ file as a source of metadevice database locations. -h Display a usage message. -k system-name Edit a user-supplied system-name instead of the default /etc/system system configuration information file. -m md.conf-name Edit the configuration file specified by md.conf-name rather than the default, /kernel/drv/md.conf. -n Print what would be done without actually doing it. -R root-path When metaroot modifies system files, it accesses them in their relative location under root-path. The -R option cannot be used in combination with the -c, -k,-m, or -v options. Note - The root file system of any non-global zones must not be referenced with the -R option. Doing so might damage the global zone's file system, might compromise the security of the global zone, and might damage the non-global zone's file system. See zones(5). -v vfstab-name Edit vfstab-name instead of the default /etc/vfstab table of file system defaults. OPERANDS
The following operands are supported: device Specifies either the metadevice or the conventional disk device (slice) used for the root file system (/). EXAMPLES
Example 1 Specifying Root File System on Metadevice The following command edits /etc/system and /etc/vfstab to specify that the root file system is now on metadevice d0. # metaroot d0 The following example shows the same command using a desriptive name for the metadevice. # metaroot newrootfilesystem Example 2 Specifying Root File System on SCSI Disk The following command edits /etc/system and /etc/vfstab to specify that the root file system is now on the SCSI disk device /dev/dsk/c0t3d0s0. # metaroot /dev/dsk/c0t3d0s0 FILES
/etc/system System configuration information file. See system(4). /etc/vfstab File system defaults. /etc/lvm/ Metadevice state database locations. /kernel/drv/md.conf Configuration file for the metadevice driver, md. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. ATTRIBUTES
