KVM fujitsu-siemens S2-0801, HP 336044-B21

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!
mpt-status
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.
loop
mptctl

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