Unable to use same disk for creating two metadevicse
Hi ,
I tried creating two metadevices from same disk , but using different slices
it gave me an error saying that the new device overlaps with the earlier metadevice.
is there any rule that we cannot use same disk for two metadevices.
first i tried creating a concatenated volume from a slice having database replica on the other slice of same disk...it dint work, later i took other disk and repeated the process but this time it was not database replica but a volume.
help!!
Regards,
Laxxi

metaroot
metaroot(1M) metaroot(1M)
NAME
metaroot - setup system files for root (/) metadevice
SYNOPSIS
/usr/sbin/metaroot -h
/usr/sbin/metaroot [-n] [-k system-name] [-v vfstab-name] [-c mddb.cf-name] [-m md.conf-name] [-R root-path] device
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.
Root privileges are required for all of the following options except -h.
The following options are supported:
-c mddb.cf-name Use mddb.cf-name instead of the default /etc/lvm/mddb.cf 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.
The following operands are supported:
device Specifies either the metadevice or the conventional disk device (slice) used for the root file system (/).
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
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
/etc/system System configuration information file. See system(4).
/etc/vfstab File system defaults.
/etc/lvm/mddb.cf Metadevice state database locations.
/kernel/drv/md.conf Configuration file for the metadevice driver, md.
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
