Crear por lo menos 3 dbreplicas en un slice que no este usado, en cada drive. #metadb -a -f -c 3 c0t0d0s7 c0t1d0s7 2. Para cada slice hay que crear 3 nuevos metadevices: - uno para el slice existente - uno para el slice en el disk espejeado - uno para el mirror. Almacena esta inf en el file /etc/lvm/md.tab sin espacios entre lineas d10 1 1 /dev/dsk/c0t0d0s0 d20 1 1 /dev/dsk/c0t1d0s0 d0 -m d10 d11 1 1 /dev/dsk/c0t0d0s1 d21 1 1 /dev/dsk/c0t1d0s1 d1 -m d11 d12 1 1 /dev/dsk/c0t0d0s3 d22 1 1 /dev/dsk/c0t1d0s3 d2 -m d12 d13 1 1 /dev/dsk/c0t0d0s4 d23 1 1 /dev/dsk/c0t1d0s4 d3 -m d13 d14 1 1 /dev/dsk/c0t0d0s5 d24 1 1 /dev/dsk/c0t1d0s5 d4 -m d14 d15 1 1 /dev/dsk/c0t0d0s6 d25 1 1 /dev/dsk/c0t1d0s6 d5 -m d15 -------End File -------- Ejecutar el metainit comando para crear los metadevices definidos en el file md.tab usando la opcion -a, se crean todos los metadevices definidos previamente. # metainit -a -f # La opcion -f es necesaria pq los slices estan montados. 3. Modificar el file /etc/vfstab para reflejar los metadevices, hacer antes backup del file. # cp /etc/vfstab /etc/vfstab.orig # metaroot d0 # vi vfstab #Se muestra como hacerlo con swap, hacer para cada slice al correspondiente # mirror.Para el slice root se hace con el comando metaroot que actualiza # este file automaticamente. /dev/dsk/c0t0d0s1 - - swap ; - no - a /dev/md/dsk/d1 - - swap ; - no - # Para no confundirse Veamoos como # como se asigno esto a c/slice. --------------- EJEMPLO: d0 c0t0d0s0 3 GB / d1 c0t0d0s1 6 GB /tmp (SWAP) d2 c0t0d0s3 8 GB /usr d3 c0t0d0s4 10 GB /var d4 c0t0d0s5 20 GB /export/home d5 c0t0d0s6 21.24 GB /intercia c0t0d0s7 104.34 MB Disk Suite --------------- 5. Bloquear los filesystems antes de rebootear. #lockfs -fa 6. #Necesario reboot sino se pueden corromper datos. 7. Verificar la nva configuracion, como salida veremos metadevices no slices. # df -k # swap -l 8. Asignar el dump device al correcto device. # dumpadm -d swap Verificamos el dump device si fue setado correctamente. #dumpadm 9. Por Ultimo attachar el segundo submirro a el metamirror device, para cada particion del disk # metattach d1 d21 d1: submirror d21 is attached # metattach d2 d22 d2: submirror d22 is attached # metattach d3 d23 d3: submirror d23 is attached # metattach d4 d24 d4: submirror d24 is attached # metattach d5 d25 d5: submirror d25 is attached Verificamos la syncronizacion de datos de un disk al otro.

Removing "Drive Not Available" from Solaris
These are steps I followed to remove the LUNS which were unmasked from the system.
Removing the Unused/Unmasked LUNS from Solaris.
1. First Step is identifying the
2. Remove them from Volume Manager. In my case, they are veritas. so I used vxdisk rm
3. look at the cfgadm -al o/p to find the disks which are failing. they are failing because they are unmasked from this system and still OS sees them.
c3::50060482d53135b8,84 disk connected configured failing
c3::50060482d53135b8,86 disk connected configured failing
c3::50060482d53135b8,87 disk connected configured failing
3. luxadm -e offline /dev/rdsk/
4. cfgadm -o unusable_FCP_dev -c unconfigure c3::50060482d53135b8
# This will remove all unusable LUNS from system for particular controller and target id. don't worry there might be some
working devices on that target. This command won't affect them. they'll be in working state only.
5. clean the device files using devfsadm -Cv
6. You should be clear now in both format and cfgadm -al.
