Education day

Morning started with founding out how to rebuild a hard disk in one of the new IBM xSeries 330 servers. Everything went nice and good. Funny thing though is that IBM uses Windows for Installation disk operating system, and Linux for Support and Repair disk :) The first one gave me a blue screen while I was trying to use for the rescue. :) I also have the impression that Compaq machines are able to rebuild disk from the healthy one without booting from the rescue CD, though I am not sure. It was also strange to find out about dead disk from LEDs on the front panel of the server and not from the logs. cpqarray driver is giving me hard times with logs and console every time there is a problem with the device.

Working on netsaint2mrtg taught me to put “1;” at the end of the files that I will “require” later on. Easy thing to put it, hard to remember though, but perl errors are very descriptive. :) Both the config converter and plugin wrapper are ready now and are running in test environment with about 30 servers and 400 services monitoring. Looks nice.

Then, someone kind enough provided me with some links on Active Directory and Linux and Linux Authentication Using OpenLDAP.

To finish the day, couple of sales peopel tried to convince me that using antivirus from one vendor is way better then using programs from several vendors. Failed though.
