Hi Jordan !
In order to get my 2nd disk labeled properly I tried to fiddle around
with sysinstall a bit.
First thing that might be done better:
sysinstall is located in /stand and won't be touched by
'make worlds'. So I had on my -current system the one
from the FreeBSD Release 2.0.5. ;-)
Since between releases many things might change in
installation/maintenance area, /stand should be upgraded
during make world's...
So I had to checkout the newest -current and to build it.
To get sysinstall compiled I had to make the following
changes:
Index: release/sysinstall/Makefile

rm -f makedevs.tmp
And to get it linked properly, I had to change the directory
to ../libdisk manually to make libdisk.
Final remark on adding a 2nd harddisk properly:
Installing a 2nd harddisk with sysinstall isn't possible, because
of the many extra sanity checks in the "Label" submenu. All you
get is a "basic" disklabel in the "PARTITION" menu.
But adding filesystems into the disklabel fails. You get error
messages, that a / or /usr filesystem couldn't be found. And
even if you do so, then an error messages tells you, that the
disk couldn't be labeled.
So everything that sysinstall gives to you, is a disk, that is
"partially labeled" ;-)
Another thing is, I had to manually change the disk geometry
to 255/63 scheme. My first disk is so large (4GB) so that
64/32 head/sector mapping isn't sufficiant.
If I don't change the geometry to 131/255/63, then the
SCSI hostadapter BIOS complaints about it, that a drive
with another geometry then the default boot disk was found.
This prevents further booting, you have to press return,
so ... it's deadly required, to change the geometry manually
this time ...
The nice part within sysinstall is, that it produces a basic
disklabel, that allows you (in case you need it) to label the
disk in a way, to be compatible with other OS's partitions,
if you need it. So it reserves some extra space (53 sectors)
at the beginning of the disk.
BTW, best is, you write down the starting points and sizes
in the PARTITION submenue. You need them later, if you write
an entry for your disk in /etc/disktab.
And, a disktab entry for my fujitsu now looks the following.
The first entry was based on my first hacking without sysinstall,
the 2nd with basic help of sysinstall... The other partitions
I added here manually.
# (ahc0:1:0): "FUJITSU M2694ES-512 8139" type 0 fixed SCSI 1
# sd1(ahc0:1:0): Direct-Access 1033MB (2117025 512 byte sectors)
# sd1(ahc0:1:0): with 1819 cyls, 15 heads, and an average 77 sectors/track
# 1819cyls * 15heads * 77sectors/track = 2100945 sectors
# 1819cyls * 15heads * 78sectors/track = 2128230 sectors

What makes me wonder is, that disklabel complains, if you
choose the total sector size for the ":pc#" entry, which
- - in theory - should reflect the total sector size of the
disk. Choosing FreeBSD's slice size cures this, but it looks
strange for me. BTW: One has to be carefull with the sector
sizes for FreeBSD partitions, since the offset for the
partition sizes starts with 0, where 0 is in fact "0 + 63",
the offset of the FreeBSD slice.
It's damn work to add a 2nd Harddisk :-)
And for all of you who said "buh baeh", disklabel is outdated stuff,
when I tried to help the user, who first asked ... HOW do YOU get
a perfect disklabel for a 2nd disk, without using a proper disktab
entry ???? Which hacked up -current are you using ?! :-((
Best would be, to make parts of sysinstall to a standalone
program in /usr/sbin, where expert mode allows you to choose
a partitioning in the "LABEL" submenu, as you like, without
complaining about missing root and such ... But this seems
to be a little extra work ...
Since I already tried this and commented out three sanity
checkings in the proper places ... The warning messages
vanished, but ... the sysinstall core dumped during the
"W"rite action :-( *sigh* ;-)
What do you think about the following: don't remove the sanity
checks in "LABEL" menue ("warning, you need a / filesystem, /usr
filesystem), but make them only as WARNING's, so that one can
ignore the WARNING's and skip them.
Ok, this was a little long, but believe me, adding a 2nd disk
was a bit long, too ;-))
