Real installation is endless pain and won't work (for me).
dpavlin@klin:/opt$ wget ftp://ftp.supermicro.com/utility/IPMIView/Jar/IPMIView2-Class_v2.8.0_Build110802.zip

dpavlin@klin:/opt$ unzip IPMIView20-Class_v2.8.0_Build110802.zip -d IPMIView

dpavlin@klin:/opt$ cd IPMIView/

dpavlin@klin:/opt/IPMIView$ chmod 755 IPMIView20.sh

According to http://www.mcgill.org.za/stuff/archives/340  you should be able to run KVM stand alone:
java -cp .:::::$PWD/iKVM.jar:$PWD/IPMIView20.jar:$PWD/TrapView.jar:::::: \
        -Djava.library.path=. \
        -D tw.com.aten.ikvm.KVMMain \
        $IP $USERNAME $PASSWORD null 5900 623 2 0

java -Djava.library.path=. -jar iKVM.jar \
  $IP $USERNAME $PASSWORD null 5900 623 2 0

ZFS
disks seem to move from boot to boot so we need to specify disks for pool using persistant IDs:
zpool create -f test raidz3 `ls /dev/disk/by-id/ata-Hitachi_HDS723030ALA640_MK03* | grep -v part`

Drive LEDs
http://groups.google.com/a/zfsonlinux.org/group/zfs‑discuss/browse_thread/thread/2a822bb27a1cdce5 
hdparm I, specifically, will give you the serial number and 
 lsscsi/lsblk would probably be helpful here with topology. Lighting a 
 bay LED without relying on guessing which drive you're doing i/o is 
 doable, but more dependent on your specific adapter's tools available. 
 See also: smp_utilshttp://sg.danny.cz/sg/smp_utils.html .
Setting the fault or identify leds can be done with the sg3_utils 
 package and a carefully crafted SES command. Alternately, if you load 
 the SES kernel module you can set them via the fault and locate sysfs 
 entries.
