c0t0d0s2 represents the first system disk (boot)c0t1d0s2 represents the second disk (mirror)Duplicate the label's content from the boot disk to the mirror disk:
# prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t1d0s2
Create replicas of the metadevice state database:
# metadb -a -c3 -f c0t0d0s4 c0t1d0s4
# metadb
Option -f is needed because it is the first invocation/creation of
metadb(1m).
Creation of metadevices:
# metainit -f d10 1 1 c0t0d0s0
# metainit -f d11 1 1 c0t0d0s1
# metainit -f d13 1 1 c0t0d0s3
# metainit -f d16 1 1 c0t0d0s6
#
# metainit d20 1 1 c0t1d0s0
# metainit d21 1 1 c0t1d0s1
# metainit d23 1 1 c0t1d0s3
# metainit d26 1 1 c0t1d0s6
Option -f is needed because the file systems created on the slice we
want to initialize a new metadevice are already mounted.
Create the first part of the mirror:
# metainit d0 -m d10
# metainit d1 -m d11
# metainit d3 -m d13
# metainit d6 -m d16
#
# cp /etc/vfstab /etc/vfstab.beforesvm
# metaroot d0
Don't forget to edit /etc/vfstab in order to reflect the other
metadevices:
s@/dev/dsk/cXtYdZsN@/dev/md/dsk/dN@s@/dev/rdsk/cXtYdZsN@/dev/md/rdsk/dN@Install the boot block code on the alternate boot disk and set it in the OpenBoot Prom (OBP):
# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t1d0s0
# eeprom boot-device="disk disk1 net" /* Or just "disk disk1". */
Reboot on the new metadevices (the operating system will now boot encapsulated):
# shutdown -y -g 0 -i 6
Attach the second part of the mirror:
# metattach d0 d20
# metattach d1 d21
# metattach d3 d23
# metattach d6 d26
Verify all:
# metastat -p
# metastat | grep \%
Modify the system dump configuration:
# mkdir /var/crash/`hostname`
# chmod 700 /var/crash/`hostname`
# dumpadm -s /var/crash/`hostname`
# dumpadm -d /dev/md/dsk/d1
