Minimal OpenSolaris SPARC install

Using previous instructions I've successfully installed opensolaris 2009.06 on my TestFarm (thanks, Jim) T2000 from existing Nevada b98.
Steps are identical: my machine have 4 disks, so I've prepared third disk (c0t2d0) for installation (I take 4gb):

Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 824 4.00GB (825/0/0) 8395200
1 unassigned wm 0 0 (0/0/0) 0
2 backup wu 0 - 14086 68.35GB (14087/0/0) 143349312
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0

Next steps (it's fast):

zpool create opensolaris c0t2d0s0
zfs create opensolaris/rootfs
zfs set compression=on opensolaris/rootfs
zfs set mountpoint=legacy opensolaris/rootfs
mkdir /zfsroot
mount -f zfs opensolaris/rootfs /zfsroot

Here's minimal list of packages for my T2000 (sun4v):

I already have pkg built and installed from sources on my Nevada. Now network installation:

pkg image-create -F -f -a opensolaris.org=http://pkg.opensolaris.org /zfsroot

cd /zfsroot

for pkg in `cat pkg.lst`; do pkg install --no-refresh --no-index $pkg; done

echo "etc/zfs/zpool.cache" >> /zfsroot/boot/solaris/filelist.ramdisk

zpool set bootfs=opensolaris/rootfs opensolaris

echo "opensolaris/rootfs - / zfs - no -" >> /zfsroot/etc/vfstab

mkdir -p /opensolaris/platform/sun4v

cp /zfsroot/platform/sun4v/bootlst /opensolaris/platform/sun4v/

cp /zfsroot/lib/svc/seed/global.db /zfsroot/etc/svc/repository.db

devfsadm -R /zfsroot

bootadm update-archive -R /zfsroot

installboot -F zfs /platform/sun4v/lib/fs/zfs/bootblk /dev/rdsk/c0t2d0s0

This install take only 630 mb. Now I can adjust my network settings and install additional packages.

Get detailed disk info with Caiman libraries

Using Caiman libraries you can write small programs which can be very useful in sysadmin's daily work or can help making your own installer. For example, using libtd (Target Discovery) library you can get info about system disks and partitions very fast. Here's an example of using libtd test program (test_td):

# ./test_td -d
Disk discovery
Total number of disks: 3
---------------------------------
num | name| ctype|size [MB]|
---------------------------------
1 | c2t0d0| usb| 976|
2 | c0d0| ata| 76350|
3 | c1d0| ata| 38166|
---------------------------------

# ./test_td -p all
Partition discovery for all disks
-------------------------------------
num | name| active| ID| lswp|
-------------------------------------
1 | c2t0d0p1| Yes| BF| No|
2 | c0d0p1| Yes| BF| No|
3 | c1d0p3| No| 83| No|
4 | c1d0p2| Yes| 83| No|
5 | c1d0p1| No| 82| Yes|
-------------------------------------

Now verbose output:

# ./test_td -d -v
Disk discovery
Total number of disks: 3
-------------------------------------------------------------------------------
num | name| vendor| ctype| mtype| rem| lbl| bsize|#of blocks|size [MB]|
-------------------------------------------------------------------------------
1 | c2t0d0| Multi| usb| FIXED| Yes| VF| 512| 1999872| 976|
2 | c0d0| unknown| ata| FIXED| No| VF| 512| 156364992| 76350|
3 | c1d0| unknown| ata| FIXED| No| VF| 512| 78164352| 38166|
-------------------------------------------------------------------------------

# ./test_td -p all -v
Partition discovery for all disks
---------------------------------------------------------------------
num | name| active| ID| lswp| 1st block|#of blocks|size [MB]|
---------------------------------------------------------------------
1 | c2t0d0p1| Yes| BF| No| 2048| 1996800| 975|
2 | c0d0p1| Yes| BF| No| 16065| 156344580| 76340|
3 | c1d0p3| No| 83| No| 20547135| 57609090| 28129|
4 | c1d0p2| Yes| 83| No| 1012095| 19535040| 9538|
