Hi Haroon,
A disk marked as FORMER can be safely added to a new diskgroup, as this status
means that the disk was cleanly removed from an old diskgroup. As per the 11.2
documentation:
"From the perspective of the installation, candidate disks are those that have
the CANDIDATE, PROVISIONED, or FORMER header status. These disks with a
CANDIDATE, PROVISIONED, or FORMER status can be added to Oracle ASM disk groups
without using the FORCE flag."

Kind Regards,
Lucas Pimentel Lellis

thanks for the replies. I did drop the diskgroup and the header status is
marked as FORMER (v$asm_disk). I know that it means that the disk was formerly
part of a disk group but not sure if it means it is a candidate for a adding to
a diskgroup and if anything else needs to be done to the disk before using it.

you probably want to drop the diskgroups first though.

I believe the command is /etc/init.d/oracleasm deletedisk <disk name> to clear
and drop a disk, then just re-run the createdisk command to re-initialize it.

Hello,
i need to recreate my database (test database) running 11.2.0.3 on RHEL 6.4
with ASMLIB. I want to reuse the same LUNS that I had before and recreate the
diskgroups. How can I tell ASM to reuse the same disks? Do I need to do
something to the disks first in order to be able to reuse them? I do want to
clear out the disks as well so that there is nothing on them.
Thanks in advance,
Haroon
