[OpenIndiana-discuss] Anything special todo to used discs on fresh install

[Harry Putnam]

Setup: running oi-151_9 on:
 Hardware: HP xw8600 - 2x Xeon  CPU X5450 @ 3.00GHz - 32 GB ram

I'm about to try installing hipster from the 161030 gui iso on the
above hardware that has been running build 151_9 for something like 2
yrs maybe more.

I've had some good helpful posts on how to get this done.  But as I
get nearer to actually doing it... I began to worry about the discs.
I'm running.  I've had the rpool on a mirrored pair of ide discs
probably a bit long in the tooth, but trouble free. And expect to
continue running them as mirrored rpool.

Nilolas M tried to explain to me, how to handle the new grub / new
boot loader kind of problem but some of it flew right over my head.

So the IDE discs I'll use for rpool currently have grub in the MBR.

Are there steps I need to take to rid them of grub? Something I can do
once the machine is shutdown and booted with a livecd or something.

And what about the data on them... does it need removed in some way?
I mean beyond deleting.

That last bit also goes for the other 4 discs but they are all sata.

Is there something beyond deleting data that needs to be done?
