How to destroy corrupt zpool without importing it?

UNIX Solaris
1

A couple of spare disks have been added to a Solaris 10 system, and one of them has a corrupt zpool on it.
I don't care about the data: I want to destroy it and re-use the disk, but it's corrupt so I can't import it. The corrupt pool is called "rpool" so I don't want to destroy it by name (obviously), but I can't destroy it by ID either.
Can anyone suggest anything?
Many thanks

I'd be likely to try running 'format' in expert mode:

 # format -e

and be VERY CAREFUL to select the correct disk, and then nuke the data on the drive (perhaps by reformatting and in the extreme using 'analyze' to write zeros to every sector). That ought to do it.

However, be very careful. Expert mode gives you extra options and doesn't ask for much confirmation. You've told Solaris that you're an expert so you'd better be one!

Create a zpool over that disk using force option.

zpool create -f newpool c0t5000CCA0129E0BE0d0s1

Hope that helps
