ASMLIB - Adicionando discos

--para linux com asmlib
--dentro do asm, verifique os paths e discos que compoem os seus DGs

------------------------------ ------------------------------ ---------- ---------- ---------- ----------
MANVOL1 ORCL:MANVOL1 272383 89385 182998 67.18
MANVOL2 ORCL:MANVOL2 272383 89403 182980 67.18


--segundo passo é identificar os discos atuais, execute os comando abaixo com root
[oracle@bdMANprd01:MANprd disks]$/etc/init.d/oracleasm listdisks
MANVOL1
MANVOL2

/etc/init.d/oracleasm querydisk /dev/*, alguns discos virão marcados como ASM disk, os demais são de so e não nos interessa --*/

ex:
[root@bdMANprd01 ~]# /etc/init.d/oracleasm querydisk /dev/* --*/

Disk "/dev/sdb1" is marked an ASM disk with the label "MANVOL2"
Disk "/dev/sdc" is not marked an ASM disk
Disk "/dev/sdc1" is not marked an ASM disk
Disk "/dev/sdd" is not marked an ASM disk
Disk "/dev/sdd1" is marked an ASM disk with the label "MANVOL1"
Disk "/dev/sde" is not marked an ASM disk
Disk "/dev/sde1" is marked an ASM disk with the label "MANVOL2"
Disk "/dev/sdf" is not marked an ASM disk
Disk "/dev/sdf1" is not marked an ASM disk

--apos o reboot, que é necessário para apresentar os novos discos e validar a criação das novas partições, como root, crie os novos discos:
/etc/init.d/oracleasm createdisk MANVOL1001 /dev/mapper/mpath0p1
/etc/init.d/oracleasm createdisk MANVOL1002 /dev/mapper/mpath1p1

No asm esses novos discos irão aparecer como candidatos, basta adiciona-los ao DG e está pronto.
