PERC 6 / I foreign config disk / how do I erase a disc

Hello

I replaced a RAID-5 disk with a hot spare that already has a foreign Config on that. I want to delete the config to the hand, I can scratch the disc so it will be detected as empty? (DD if = / dev/null of = / dev/sda)

Best regards

Eddy

is this drive or the drives part of a raid configuration or drive tottaly does not work in the raid 5 or raid 1?

Neither.  He is not currently a member of an array, but foreigners does not mean that it is totally "does not work".  The controller detected a configuration on the drive that does not match the other (s) in the table, so he scored like aliens until the admin can determine the best course of action for this.  It's absolutely a dangerous thing to (leave the admin to know the right thing to do with it), but this prevents the controller having to make decisions about the data, which makes it the responsibility of the admin to learn the skills needed to manage this live/die.

You have two options with foreign configurations:

IMPORT - must never be used when multiple disks are marked strangers simultaneously, including moving leads to a new controller/system, etc. and must be used when an array is offline.

CLAIRE - should be used whenever the table is online and only one drive is marked foreign (or several disks in case it's a RAID 10/50/60, but the picture is still online). It is usually the case when a disk fails (or is a failure) or simply disconnects due to a timeout, etc. and is often the case when replacing a failed drive in an array.  Only after the cancellation of the foreign configuration the drive is possible a hot spare for the table in order to rebuild the disk in the array.
