Hi,

I use dd and write zeros on top of the signature.   That data is stored at the end of the drive, so it takes a hours get it done.

dd if=/dev/zero of=/dev/sd{whatever} bs=64k

How are you supposed to clear the configuration on a disk previously
used on a PERC 5/i?


# omconfig storage controller action=clearforeignconfig controller=0
Command successful!

# omconfig storage pdisk action=clear controller=0 pdisk=0:0:1
Operation disabled. Read, action=clear

# omreport storage pdisk controller=0
