conferences, that are worth visiting. This was still before I have been to conference itself and I was just relying on experience of a friend and was actually just on a way to the conference itself. Now I am back and I am still trying to grasp it all, since I was literally “Blown away”. E2EVC is much more as I expected or could even hoped for. Most of other conferences, I have been till now, are only a pale imitation. Continue reading “E2EVC is what I was looking for!”
It is not so long time ago, when I was asked how do I manage to stay up to date with so many technologies and how am I able to follow so many streams of news that are available each day.
The answer is simple. I DO NOT MANAGE IT, but I do the best I can. I do not think, that there is simple solution or single way to walk. I also doubt, that the path I am walking will work for you, but I hope you might find a thing or 2 useful and maybe you can try it out. Please let me know if it worked for you as well.

I was not actively involved in managing our production Storage Spaces Direct (S2D) infrastructure for few weeks now, but this weekend I was asked to help with an issue and through this I again learned a lot new. Some of my findings I want to share here with you.
Story leading to error…
This weekend was reserved for patching production S2D servers (Windows server 2016 RTM – core) with several patches out of 2018-04 bundle (KB4093119, KB4093120 and KB4093137; ##update# Error is not bound to this April CU only and has been seen earlier.##). Prior doing this, we also updated Firmware versions on our Cisco UCS servers. YES, this are the same servers I had trouble connecting to few days ago and I blogged about solution here.
It all started easy and first (out of 6) server was updated without a glitch. There was also no troubles for StorageJobs to complete and all S2D volumes were up and healthy. OK. Time to go to second server… Here all updates also had no trouble to install.
Trouble with Physical drives…
After completed patching, we were faced with surprise. Continue reading “Some of S2D physical disk drives in Transient error”
It happened to me already several times, that Cisco IMC console was unavailable after several days of not using it. It cannot be accessed via Web Browser (as if page would not exist) or via CIMC supervisor, as you can see it in screenshot below.
The simplest solution to this is, to power server off, pull all the plugs, wait for some seconds and give server a chance for a new start.
…but there is also a better and less destructive way
As you might already know, I put more focus into IT security in last couple of months. So besides looking for IT technology conferences and gatherings, I have also started to look around for conferences with emphasis on IT security. So I had opportunity to visit 2 of the in this month. First one was BSides Ljubljana, which is prepared by community enthusiasts, while second one Risk Conference 2018 is commercial conference prepared by Real Security. Despite obvious differences in budget, I cannot stop myself comparing them.
