SVM (Solaris Volume Manager) to mirror the disk

    The following is an example to install our application and informix database  on the same 72G disk on Sun V210, then mirror the rootdisk with the second . Also I listed the procedure to create the raw devices for informix data, which has taken me lots of time to mirror it. (although the soft partition and submirror are metadevice , they can't be as a unit the valid unit to setup)

#Partition the rootdisk

Slice    mountpoint    size    start-cyl    end-cyl
0        /            5120
1        swap        8193
2        overlap        entire-disk
3                    258
4                    Free
5        /opt        8193
6        /var        9899
7        /app_log        12288

#Set the same Partition layout for the second disk with the first disk

fmthard -s boot-vtoc.tab /dev/rdsk/c1t1d0s2
