下面的示例显示创建镜像 d4 以镜 像 /home,/home 驻留 在 c0t0d0s4中。镜像 d4 由 分区 c0t0d0s4 中的子镜像 d14 和分 区 c2t2d0s4 中的子镜像 d24 组成。/home 的 /etc/vfstab 文件条目更新为使用镜像名称 d4。磁盘 c2t2d0 是一个多端口连接的磁盘,因而启用了 localonly 特性。
(Create the mirror:)
# metainit -f d14 1 1 c0t0d0s4
d14: Concat/Stripe is setup
# metainit -f d24 1 1 c2t2d0s4
d24: Concat/Stripe is setup
# metainit d4 -m d14
d4: Mirror is setup
(Edit the /etc/vfstab file:)
# vi /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
/dev/md/dsk/d4 /dev/md/rdsk/d4 /home ufs 2 no global
(Attach the second submirror:)
# metattach d4 d24
d4: Submirror d24 is attached
(View the sync status:)
# metastat d4
d4: Mirror
Submirror 0: d14
State: Okay
Submirror 1: d24
State: Resyncing
Resync in progress: 15 % done
...
(Identify the DID name of the mirrored disk's raw disk device group:)
# scdidadm -L
...
1 phys-schost-3:/dev/rdsk/c2t2d0 /dev/did/rdsk/d2
(Enable the localonly property of the mirrored disk's raw disk device group:)
# scconf -c -D name=dsk/d2,localonly=true
