Samesame, but different software. Same functions.
I Got two of them but one was DOA, so I quickly swapped the internal powersupply DSO-142L and that was the error.

Some of the capacitors on the low-voltage side looks suspicious and I replaced them,
The original was
CapXon LZ vent c422 2200uf,10V
CapXon LZ vent c422 470uf,10V
and two
CapXon LZ vent c420 470uf,10V
I did not have exactly same so I used:
United 2200uF,16V and 3xUnited 470uF,25V
They are thicker but I raised them a little and it fits Ok.
And now my powersupply is working again.

smartmontools is a very informative tool!
smartctl -a /dev/sg2 will show lots of information from my harddrive
/dev/sg3 is the other drive.
for instance Current Drive Temperature reads 37 C
and 40 degrees C for the other.
And has been working for 34258 hours

hddtemp is a other useful too which as you probably figure out, show you harddrivetemperature: also an debian package ready to apt-get install.

hddtemp /dev/sg2 /dev/sg3
/dev/sg2: IBM-ESXSST373453LC FN: 37°C
/dev/sg3: IBM-ESXSST373453LC FN: 40°C

SCSI status MPT-Status

The two scsi-discs is connected (SCSI 80 pin) to a LSI53C1030 raid1 interface .
As I run debian etch,I installed a debian-package “mtp-status
apt-get install mpt-status, fetch and install mpt-status  1.1.6-13

Some tweaking will be necessary to get in to work automatic.

First run mpt-status –autoload and se if it complains. Mine did:
open /dev/mptctl: No such file or directory
Try: mknod /dev/mptctl c 10 220
Also make sure mptctl is loaded into the kernel

So then you cat test what it suggest and try again
or you can try modprobe mptctl.
And bingo!
ioc0 vol_id 0 type IM, 2 phy, 68 GB, state OPTIMAL, flags ENABLED
ioc0 phy 0 scsi_id 0 IBM-ESXS ST373453LC    FN B85E, 68 GB, state ONLINE, flags NONE
ioc0 phy 1 scsi_id 1 IBM-ESXS ST373453LC    FN B85E, 68 GB, state ONLINE, flags NONE

I don´t want to do this after each boot,
Just add mptctl into /etc/modules so it reads:
# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with “#” are ignored.

And it will work after boot.
mail is to root by default,  /etc/init.d/mpt-statusd
