I just went through several iterations of this, and like you the last time I
had done it was long ago. The following is based on 2021.04.05.
Large disks require an EFI or GPT label. The gparted program creates 128 slices
which is a bit much. format(1m) will also write an EFI label which is usable
with large disks.

You should now have a Sun EFI label with 9 slices. 8 is set by format(1m) and
can't be changed. The other two should be the ones you created.
In the first text installer screen chose F5, in the 2nd screen select the slice
you want to use. Continue with the install. When It completes reboot to single
user.
zfs create -V <size> rpool/dump rpool
zfs create -V <size> rpool/swap rpool
dumpadm -d /dev/zvol/dsk/rpool/dump
swap -a /dev/zvol/dsk/rpool/swap
touch /reconfigure
init 6
You should now come up with rpool in the 100 GB slice.
That said, we can boot from RAIDZ now. The text-install on the Desktop live
image will let you create a mirror, RAIDZ1 or RAIDZ2 and will take care of all
the label stuff. Despite the statement that it will only use 2 TB, it in fact
uses the entire disk.
It creates a 250 MB s0 slice and the rest of the disk in s1. The 250 MB slice
is labeled "System", but I've not seen any explanation of it. I've also created
RAIDZ2 pools by hand and used F5 to install into them. F5 appears to be
intended to install into a new BE in an existing pool, hence the need to set up
dump and swap by hand.
Ultimately I decided I didn't care about 1 GB of unused space in 16 TB of
space. So I just went with the text-install created RAIDZ2 pool. The
reconfigure on the first boot after the install is critical to getting
2021.04.05 up properly.

OK - I appear to be well out of touch.
I booted the installer and went into prompt.
Used format (only 1 x 6TB drive in the machine at this point) to create
a new Solaris 2 partition table and then fdisk'd an all free hog to
partition 1, giving partition 0 100gig.
I noticed that it must have gone on for 40 odd partitions, and also
there was none of the usual backup and reserved partitions for 2, 8 and
9 as I saw before.
On installation of OI, I selected the drive and got the warning...
"you have chosen a gpt labelled disk. installing onto a gpt labelled
disk will cause the loss of all existing data"
Out of interest I continued through and got the options for whole disk
or partition (MBR) ... the second of which gave me a 2Tb Solaris 2
partition in the list.
I did try F5 to change partition, but it just took me straight back to
the installation menu at the start again.
Things have obviously moved on and I haven't kept pace.
I now have to work out how to do this on a gpt drive.
If anyone has any notes, I'd be grateful.
Michelle.
