Mirror boot con Solaris Volume Manager

El equipo tiene 2 discos internos de 72 gb.
Vamos a usar el disco c1t0d0 como disco primario y el c1t1d0 como disco de mirror
[SKOL] /etc/init.d # format
AVAILABLE DISK SELECTIONS:
0. c1t0d0
/pci@1c,600000/scsi@2/sd@0,0
1. c1t1d0
/pci@1c,600000/scsi@2/sd@1,0
Specify disk (enter its number): ^D

El disco c1t0d0, tiene 3 particiones usadas, el slice 0 para el fs /, el slice 1 para el swap y el slice 3 para el fs /u00.
Se necesita como minimo 2 State Database REplicas por disco. que es donde DiskSuite va a almacenar los datos de
configuracion e informacion de Disksuite.
Por eso voy a usar el slice 4 y 5 del disco, con 15 mb para cada slice. Para esta tarea uso el comando format.

Posteriormente, voy a copiar toda la informacion contenida en el disco c1t0d0 (slices,tamanio,etc) en el disco que se
usara como mirror, en este caso el c1t1d0
prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
Chequeo que lo haya hecho con el comando format.

Luego de eso, creo los state databse replicas, de la siguiente manera

[SKOL] / # metadb -a -f -c 2 /dev/dsk/c1t0d0s4 /dev/dsk/c1t1d0s4
[SKOL] / # metadb -a -f -c 2 /dev/dsk/c1t0d0s5 /dev/dsk/c1t1d0s5

donde -a significa adding
-f significa force, porque es la primera vez que se esta creando las bases.
-c 2 ( con espacio entre la c y el 2), significa que crea 2 databases en cada slices.
