Label erase 7.54 is the command if I recall.
My recommendation is to call NetApp support and have them walk you
through it. The BEST course of action is to have the drive with the
'bad' label replaced via RMA.

Subject: RE: downgrading the firmware on NetApp drives
I wish the old machine still existed so that I could zero the old drive
on that machine. That would sure help!
Even in priv set diag I don't see the disk_erase_label command. The bad
drive is 7.54. What would be the syntax for the command and what priv
would I have to use to execute it? I hope I don't do something horrible
and erase all the disklabels or something.
Am I looking in the wrong place? How do I use the "ok" at the boot
prompt?

Hi,
Thats not a firmware problem thats the disk label.
Essentially the disk was removed from a filer running a later version of
OnTap so the version of OnTap in the filer thats trying to read it can't
understand it.
Theres two possible ways of fixing it (that I know of, one of the gurus
might no a better way)
1) Put the disk back in the old system (or a system running a later
version of OnTap) and then zero the disk
2) Reboot the filer and use the label erase command (I might be
rmisrmembering the actual command..it's documented on Now) which is a
command from the Ok prompt
Andrew

Subject: downgrading the firmware on NetApp drives
I found a 36GB NetApp drive for my f740 with FC9 shelves and when I put
it in the machine, it said:
Tue May 23 19:14:07 EDT [raid.assim.disk.badlabelversion:error]: The
label on disk 7.54 (S/N 3CD0FN3X000021098HUD) is a newer version than
that supported by this software. Either remove the disk or upgrade the
system software.
Of course, the disk_fw_update command didn't work because the versio of
the firmware is NEWER than what's supported by my OS (Data Ontap
6.4.4p7). How does one go aboot DOWNGRADING the firmware on a NetApp
drive?
