Four days in Irkutsk
I will be away for the next four days due to a trip to Irkutsk where I’m going to work with Sun 9990 and SF6900.
A bigger four and a smaller one
Yeah, it sounds awkward an at very least unusual but I don’t know how to express in other words that today is my son’s birthday – he has just turned four years young. Not old but young – it’s we who are getting old. What a day! But at the same time just two days […]
Solaris Live Upgrade
In the following post I’d like to go through in a step-by-step manner an upgrade process of Solaris OS.

Brooding about upcoming Oracle hardware service changes
Just read this on the opensolaris mailing list yesterday and if you don’t follow it then this information could be of big interest.

EIS-DVD, where are you?
Hope that’s just a temporal mess which will be successfully resolved soon. Frankly speaking, I could hardly imagine a Sun field engineer without EIS. The EIS team regrets that EIS-DVD 23FEB10 has been cancelled. This is due to purchase order approval changes for manufacturing and distribution as a result of the transfer of control to […]
Runlevels in HP-UX and Solaris
In the following post I’d like to dwell upon differences between the run levels in Solaris and HP-UX. So first, lets take a quick look at the description (man init(1M)) of the run levels which are supported in these two operating systems: HP-UX Solaris Apart from obvious distinctions between run levels with the same numbers, […]
