But I don't think it would erase disks in parallel. So I might want to do 1
disk at a time maybe?

Thanks for the heads up.
My main question is regarding running them in parallel. Sorry, if it
wasn't very clear.
Do you know what size your disks were?
We have a time constraint. Need to get off the gear ASAP! 😐
I can push it to the limit and don't even mind of the system blows 😂
It would be great if you could recollect the commands from your notes.
I am planning to do a 7 pass on flash disks and 3 pass on physical disks.

Planning on running

CellCLI> DROP CELL ERASE=3pass
Kind regards,

Hi
I have done a 7 pass erase on a half rack V2 which took about 8 hours.
1 hour for the flash disks and 7 for the cell disks. I am unsure why
resource usage is a concern when you are decommissioning the kit.(you
obviously do not have any apps running on the kit)
Please note that any grid disks which are inactive/offline will not be
scrubbed
Thanks

Howdy Guys!
We got to returned our leased old exadata boxes and need to destroy all
time.
Oracle says they don't want us to erase more than 2 disks at the same
Their recommendation would take us forever to get out of the box.parallel.
Has anyone got any experience with this? Especially wiping disks in
The guy from Oracle says it consumes a LOT of CPU.
I think it should be IO bound. Why does he say that?
Thanks!
