scrub disks (how to)

we are retiring 14 shelves and would like to scrub the disks, before
giving them up.

anybody got any pointers ?

(begin rant)
on a side note, i think its not fair that netapp does not give a credit
when returning disk shelves. (ok rant over)

if you have an older machine, you can initialize them during setup.

If your ontap is recent enough (dont' remember the version) you can use
disk sanitize from the command line.

Hello Chaim:

There is a few things you can do. If you are retiring an entire system, after moving production data to the new system, you could bring the system to the boot menu and choose 4, to re-initialize all disks.

Assuming that you don't want to wipe out all the disks associated with the sytem, then you will probably want to use the "disk" command with the "sanitize" option. The saniztize option requires a license. I have no idea how pricing for sanitize works but the command is very effective for wiping out data.

You could place the disks in the spares pool and issue
"disk zero spares"

Hi,
Sanitize is a free license.
You can get a license key from your Sales Rep.

Re: scrub disks (how to) [In reply to]

Re-initializing the system will only write zeroes to all disk then
create a new root volume.

Disk Sanitizer (free license available from your NetApp rep) is
configurable as to how many passes and patterns you use on the list of
disks you provide to it. Expect this option to be very lengthy, but
much more thorough than simply re-inializing the entire system or
zero-ing your spares.

fyi -- the disk sanitization license is not removable so be careful
if you want to use it. It was aimed at gov/military sanitization
requirements so you can't remove it mid stream and then look at the data
thats left.

Re: scrub disks (how to) [In reply to]

When I use the license, I remove all essential disks (i.e. keep the ones I
want to sanitize in the system)
I then boot to main menu, choose #4 to zero and install.
After it is done, I install the OS as normal and then add the DISK_SANITIZE
license.
I then sanitize all the disks that are left. I am still left with two right.

I create a new root volume on two of the sanitized disks and then delete the
old root volume
and sanitize those disks.

Re: scrub disks (how to) [In reply to]

No need to remove any disks. When you run the command, you pass it a
list of the disks you wish to sanitize.

e.g. disk sanitize start 0a.16 0b.23

This will sanitize disks 0a.16 and 0b.23 using the default hex pattern
of 0x55 0xAA 0x3c. This will result in those disks being overwritten 3
times, once for each pattern. To be in compliance with DoD and DoE
requirments, you have to overwrite at least 6 times.

http://now.netapp.com/NOW/knowledge/docs/ontap/rel707_vs/html/ontap/mgmtsag/3disk17.htm has detailed information.

Re: scrub disks (how to) [In reply to]

Let me finish what I wanted to say ;)

If you do not want the DISK_SANITIZE license on your system when you are
done....

follow what I do...once you license it, you cannot remove it. I for one, do
not like it sticking around
so I sanitize in an isolated environment.
